Variations
To truly make these Rhubarb Sticky Buns your own, consider these delightful variations that cater to different tastes and dietary preferences. Each adaptation offers a unique twist while maintaining the comforting essence of the original recipe.
Berry Burst Delight: For a delightful departure from rhubarb, try substituting it with a generous cup of fresh blueberries or a mixed berry blend. The natural sweetness and vibrant colors of berries offer a wonderful contrast and complement the creamy frosting beautifully, making these buns a taste of summer any time of year.
Aromatic Spice Infusion: Elevate the brioche dough by incorporating a teaspoon of ground cinnamon or nutmeg. This simple addition introduces a warm, comforting aroma and flavor that pairs exceptionally well with the tangy rhubarb, creating a more complex and cozy pastry perfect for cooler days or festive occasions.
Nutty Texture Enhancement: For an added layer of satisfying crunch and rich flavor, consider folding in about half a cup of chopped pecans or walnuts into the rhubarb jam filling before spreading it on the dough. The nutty notes provide a wonderful textural contrast to the soft bun and smooth frosting.
Vegan Indulgence: To create a dairy-free and vegan-friendly version, substitute the whole milk with unsweetened almond or oat milk. For the mascarpone frosting, a rich, creamy cashew cream or a high-quality vegan cream cheese can be used, alongside a plant-based whipping cream alternative.
Citrus Zest Elevation: Brighten the mascarpone frosting with the addition of finely grated zest from one lemon or orange. This subtle hint of citrus cuts through the richness, adding a refreshing lift that harmonizes wonderfully with the rhubarb’s tanginess and makes the overall flavor profile even more dynamic.
Gluten-Free Adaptation: For those who need to avoid gluten, the brioche dough can be successfully made using a high-quality gluten-free all-purpose flour blend. Ensure the blend contains a binder like xanthan gum. You may need to slightly adjust the liquid content and kneading time for optimal results, as gluten-free dough behaves differently.
Chocolate Lover’s Dream: For an extra decadent touch, melt some dark chocolate and drizzle it generously over the frosted buns. This addition transforms the already delightful sticky buns into a truly indulgent dessert, perfect for satisfying any serious chocolate craving.
Tropical Escape: Introduce a taste of the tropics by finely dicing a small portion of fresh pineapple and adding it to the rhubarb jam mixture. The sweet and slightly tart pineapple, when cooked down, adds an exotic flair that makes these buns feel like a vacation in every bite.
How to Prepare Rhubarb Sticky Buns
Step 1: Crafting the Perfect Brioche Dough
Begin by gathering your ingredients for the brioche dough, which will form the soft, airy foundation of your sticky buns. In a large mixing bowl, combine 4 cups of all-purpose flour with 2 teaspoons of active dry yeast and 1 teaspoon of salt; this dry mixture provides the structure and lift. Next, gently warm 1 cup of whole milk to approximately 110°F, just warm enough to activate the yeast without killing it, and stir in 1/4 cup of granulated sugar until it dissolves completely. This sweet, milky liquid is crucial for hydrating the flour and feeding the yeast, setting the stage for a beautifully risen dough. Pour this activated milk mixture into the bowl with the dry ingredients, and then add 3 room-temperature eggs and 1/2 cup of softened unsalted butter. The eggs contribute richness and structure, while the softened butter ensures a tender crumb and luxurious mouthfeel.
Using a stand mixer with a dough hook attachment, or your hands, begin to mix the ingredients until they just come together to form a shaggy ball. Gradually increase the mixer speed or continue kneading by hand for about 5 to 7 minutes. The goal is to develop the gluten in the flour, which will give the dough its characteristic elasticity and airy texture. You’ll know the dough is ready when it’s smooth, supple, and pulls away cleanly from the sides of the bowl, feeling elastic and slightly tacky but not overly sticky.
Step 2: The First Rise – Letting the Dough Ascend
Once your brioche dough has been thoroughly kneaded and has achieved a smooth, elastic consistency, it’s time to let it rest and rise. Lightly grease a clean, large bowl with a little cooking oil or butter, and transfer the kneaded dough into it, turning it once to coat the entire surface. This prevents the dough from drying out as it proofs. Cover the bowl tightly with plastic wrap or a clean, damp kitchen towel, which helps maintain a humid environment conducive to yeast activity. Place the covered bowl in a warm, draft-free location in your kitchen; this could be on top of a slightly warm oven (turned off, of course), near a sunny window, or simply in a cozy corner of your countertop.
Allow the dough to rise undisturbed for approximately 1 to 1.5 hours, or until it has visibly doubled in size. The exact time will depend on the ambient temperature of your kitchen; warmer environments will speed up the process, while cooler ones will slow it down. You’ll know the dough is ready when it looks impressively puffed up and has expanded significantly beyond its original volume, appearing light and airy.
Step 3: Preparing the Tangy Rhubarb Quick Jam
While your brioche dough is diligently rising, you can turn your attention to preparing the star of the filling: the rhubarb quick jam. This jam provides a delightful tartness that beautifully balances the sweetness of the buns and frosting. In a medium saucepan, combine 2 cups of freshly diced rhubarb with 1 cup of granulated sugar and 1 tablespoon of fresh lemon juice. The rhubarb is the main flavor component, bringing its signature tartness. The sugar not only sweetens but also helps to break down the rhubarb and thicken the jam, and you can adjust its amount slightly depending on how tart your rhubarb is. The lemon juice brightens the rhubarb’s natural flavor and adds a touch of acidity that complements the overall profile.
Place the saucepan over medium heat and cook the mixture, stirring occasionally, until the rhubarb has softened and broken down into a jam-like consistency. This typically takes about 10 to 15 minutes. You’ll achieve the perfect jam consistency when a spoonful dripped from the spoon holds its shape briefly before slowly running off. Avoid overcooking, which can make the jam too thick, or undercooking, which might leave the rhubarb too firm. Once prepared, remove the jam from the heat and allow it to cool completely before using it as a filling for your sticky buns. This cooling step is essential to prevent it from melting the dough prematurely.
Step 4: Shaping the Dough for Rolling
After your brioche dough has completed its first rise and has doubled in size, it’s time to gently deflate it and prepare it for rolling. Punch down the dough by pressing firmly into its center with your fist; this releases the trapped gases and makes the dough more manageable. Turn the dough out onto a lightly floured surface, such as your clean kitchen counter or a large cutting board. This floured surface will prevent the dough from sticking during the rolling process. You can use a bench scraper to help gather and shape the dough if needed.
Using a rolling pin, begin to roll the dough into a large, even rectangle. Aim for a thickness of about 1/4 inch. The exact dimensions will depend on your dough’s elasticity, but try to achieve a shape that is roughly 12×18 inches or similar. Ensure the thickness is consistent across the entire surface; uneven thickness can lead to uneven baking. This large, flat canvas is now perfectly prepared to receive the delicious rhubarb jam filling.
Step 5: Filling and Rolling the Log
With your brioche dough rolled out into a uniform rectangle, it’s time to introduce the sweet and tangy rhubarb filling. Take the completely cooled rhubarb quick jam and spread it evenly across the surface of the dough. Use an offset spatula or the back of a spoon to ensure an even layer, reaching almost to the edges of the dough but leaving a small border along one of the long sides to help seal the log. This layer of jam is what will create that irresistible sticky texture and burst of flavor in every bite of your buns.
Once the jam is spread, carefully begin to roll the dough up into a tight log. Start from the long edge opposite the one where you left a small border. Roll it as tightly as you can without tearing the dough; a tight roll ensures that when the buns bake, they will have a beautiful swirl pattern and a good ratio of dough to filling. Once the log is rolled, pinch the seam where the dough overlaps to seal it securely. This prevents the jam from leaking out during the baking process.
Using a very sharp knife or a piece of unflavored dental floss (for cleaner cuts), slice the log into 12 equal pieces. Each piece should be approximately 1.5 inches wide. To cut with floss, slide it under the log, bring the ends up and cross them over the top, then pull to slice through the dough. Evenly spaced cuts are key for uniform buns. This step transforms the long log into individual sticky bun portions, ready for their final proof.
Step 6: The Second Proofing – Allowing the Buns to Puff
Now that you have your beautifully sliced sticky buns, arrange them in a greased 9×13-inch baking dish. Place the cut pieces cut-side up, ensuring they are spaced slightly apart but still touching each other lightly. This close proximity during proofing helps them expand and bake into each other, creating that desirable “pull-apart” texture. The baking dish should be well-greased with butter or non-stick spray to prevent the buns from sticking once baked.
Once arranged in the dish, cover the baking dish again with a clean, damp kitchen towel or plastic wrap. Let the buns proof in a warm, draft-free place for another 30 to 45 minutes, or until they have visibly puffed up and are now touching each other on all sides. This second proofing is crucial for achieving an incredibly light and airy texture in the final baked buns, making them wonderfully soft and fluffy.
Step 7: Baking to Golden Perfection
Preheat your oven to 375°F (190°C) during the last 15 minutes of the second proofing period. This ensures the oven is at the correct temperature when the buns are ready to bake. Once the buns have completed their final proof and are nicely puffed, carefully place the baking dish into the preheated oven.
Bake for approximately 25 to 30 minutes, or until the tops of the sticky buns are a beautiful golden brown color. You’ll know they are done when they have risen significantly, are golden on top, and the edges appear nicely caramelized. The kitchen will be filled with an absolutely heavenly aroma as they bake. Keep an eye on them during the last few minutes of baking to prevent over-browning, as oven temperatures can vary.
Step 8: Creating the Creamy Vanilla Bean Mascarpone Frosting
While your Rhubarb Sticky Buns are cooling slightly from their oven time, it’s the perfect moment to whip up the luscious Vanilla Bean Mascarpone Frosting. In a medium mixing bowl, combine 8 ounces of mascarpone cheese, which provides a rich, creamy base. Add 1/2 cup of powdered sugar for sweetness; you can adjust this amount slightly based on your preference for sweetness. Then, incorporate 1 tablespoon of vanilla bean paste, which offers an intense, authentic vanilla flavor with beautiful flecks of vanilla bean – a true indulgence. Finally, add 1/4 cup of heavy whipping cream to achieve the perfect smooth and spreadable consistency.
Using an electric mixer or a whisk, beat the ingredients together until the frosting is smooth, creamy, and well combined. The frosting should be thick enough to hold its shape but still easily spreadable. The warmth of the slightly cooled buns will allow the frosting to melt just slightly, creating a wonderfully decadent glaze that seeps into the crevices of the buns.
Step 9: The Grand Finale – Frosting and Serving
Once your Rhubarb Sticky Buns have cooled for about 10 minutes in the baking dish, they are ready for their final crowning glory: the vanilla bean mascarpone frosting. Using a spatula or a butter knife, generously spread the creamy frosting over the tops of each warm sticky bun. Don’t be shy – a good amount of frosting is key to this delightful treat! As the frosting meets the warmth of the buns, it will melt just enough to create a luscious, slightly drippy glaze that is utterly irresistible.
For the absolute best experience, serve these Rhubarb Sticky Buns warm, fresh from the oven and adorned with their creamy frosting. The combination of the soft, fluffy bun, the tangy rhubarb filling, and the rich, sweet frosting is truly a harmonious blend of flavors and textures. This is the moment to savor your homemade creation!
Pro Tips for Rhubarb Sticky Buns
To ensure your Rhubarb Sticky Buns turn out absolutely perfect every time, here are some expert tips that will elevate your baking experience and the final delicious result.
Ensure Dough is Well-Proofed: Patience is key for a fluffy brioche dough. Allow the dough to double in size during both the first and second proofing stages. Rushing this process can lead to dense, heavy buns, so give your dough ample time to rise in a warm environment.
Use Fresh, Quality Ingredients: The flavor of your sticky buns is directly related to the quality of your ingredients. Use fresh, vibrant rhubarb for the best tartness, and ensure your yeast is active by testing it in warm water before incorporating it into the dough. Freshness truly makes a difference in the final taste.
Manage Butter Temperature Carefully: For the brioche dough, softened, but not melted, butter is essential. If the butter is too warm, it can cause the dough to become greasy and difficult to handle, potentially affecting the gluten development and final texture. Aim for butter that yields easily to gentle pressure.
Monitor Baking Time Closely: Ovens can vary significantly, so keep a close watch on your sticky buns during the final stages of baking. They should be golden brown on top, indicating they are cooked through. Checking a few minutes earlier than the suggested time can prevent them from becoming overcooked and dry.
Frost While Warm for Best Results: Apply the mascarpone frosting to the buns while they are still warm (but not piping hot). The residual heat will slightly melt the frosting, allowing it to spread more easily and create a beautiful, slightly gooey glaze that complements the texture of the buns perfectly.
Don’t Overwork the Dough: While kneading is crucial for gluten development, over-kneading can make the dough tough. Aim for that smooth, elastic stage and then let the yeast do its work. Over-kneading can result in chewy, dense buns rather than light and fluffy ones.
Slice with Precision: For clean, even slices that result in uniform buns, use a sharp knife or unflavored dental floss. A serrated knife can also work well. Clean cuts help the buns maintain their shape during proofing and baking, leading to a more aesthetically pleasing final product.

Preparation & Storage
Proper preparation and storage are key to enjoying your Rhubarb Sticky Buns to their fullest, ensuring they remain delicious whether eaten immediately or saved for later.
Storing Leftovers
Room Temperature: Rhubarb Sticky Buns can be stored in an airtight container at room temperature for up to 3 days. They retain their softness and flavor well during this period, making them convenient for a few days of enjoyment. Ensure the container is sealed tightly to prevent them from drying out.
Refrigeration for Longer Storage: If you need to store them for longer than 3 days, transfer them to the refrigerator in an airtight container. They will keep for up to a week. However, be aware that refrigeration might slightly alter their texture, making them a bit firmer.
Freezing
Freezing Unfrosted Buns: For long-term storage, it’s best to freeze the Rhubarb Sticky Buns before frosting them. Arrange the cooled, unfrosted buns in a single layer on a baking sheet and place them in the freezer until solid, about 1-2 hours. Once frozen, transfer them to a freezer-safe bag or airtight container, removing as much air as possible, and freeze for up to 3 months.
Thawing Frozen Buns: When you’re ready to enjoy your frozen buns, the best method is to thaw them overnight in the refrigerator. This allows them to gradually return to room temperature. Once thawed, you can then apply the fresh frosting.
Reheating
Microwave Method: For a quick warm-up, place a sticky bun on a microwave-safe plate and heat for about 15-20 seconds. This is perfect for a single serving and will bring back some of that fresh-baked warmth and softness.
Oven Method: For a more even reheating, preheat your oven to 350°F (175°C). Place the desired number of buns on a baking sheet and bake for about 8-10 minutes, or until heated through and slightly warmed. This method helps to revive their texture more effectively than the microwave.
Reheating Frosted Buns: If reheating already frosted buns, use the microwave method with caution, heating for very short intervals to avoid melting the frosting too much. The oven method is generally preferable if the frosting is still intact.
Frequently Asked Questions
