Step‑by‑Step Instructions for Rhubarb Sticky Buns with Vanilla Bean Mascarpone
Step 1: Prepare the Brioche Dough
In a mixing bowl, combine 4 cups of all-purpose flour, 2 teaspoons of active dry yeast, and 1 teaspoon of salt. Warm 1 cup of whole milk to about 110°F, then stir in 1/4 cup of granulated sugar, allowing it to dissolve. Add this mixture to the flour along with 3 room-temperature eggs and 1/2 cup of softened unsalted butter. Mix until the dough forms a ball and knead for 5-7 minutes until smooth and elastic.
Step 2: Allow the Dough to Rise
Transfer the kneaded dough to a greased bowl, covering it with a damp cloth or plastic wrap. Place it in a warm spot, allowing it to rise until it doubles in size, about 1 to 1.5 hours. When ready, the dough should look puffy and expand beyond its original size, signaling it’s ready for the next step of making Rhubarb Sticky Buns.
Step 3: Make the Rhubarb Quick Jam
While your dough is rising, prepare the rhubarb quick jam. In a saucepan, combine 2 cups of diced fresh rhubarb, 1 cup of granulated sugar, and 1 tablespoon of lemon juice. Cook over medium heat, stirring occasionally until the mixture thickens, approximately 10-15 minutes. You’ll know it’s ready when the rhubarb breaks down and the jam holds a spoonful without dripping too quickly.
Step 4: Roll Out the Dough
Once the dough has risen, punch it down to release excess air, then turn it out onto a floured surface. Roll the dough into a large rectangle, about 1/4 inch thick. Use a rolling pin for even thickness, ensuring your work surface is well-floured to prevent sticking. The dough should be pliable and smooth, ready to embrace the tangy rhubarb jam.
Step 5: Spread the Jam and Roll
Evenly spread the cooled rhubarb quick jam over the rolled-out dough, making sure to cover it from edge to edge. Starting from one long side, carefully roll the dough into a tight log. Pinch the seam to seal it and use a sharp knife to slice the log into 12 equal pieces, each about 1.5 inches wide.
Step 6: Second Proofing in the Baking Dish
Place the cut pieces of sticky buns into a greased 9×13-inch baking dish, making sure they are evenly spaced and touching slightly. Cover them again with a damp cloth and let them proof for another 30-45 minutes until they puff up and slightly touch each other. You’ll see they will become fluffy and almost double in size again.
Step 7: Bake Until Golden Brown
Preheat your oven to 375°F. After the second proofing, place the baking dish in the oven and bake for 25-30 minutes or until the tops are golden brown. You’ll know they are done when the sticky buns have risen beautifully and the tops are a warm golden color, filling your kitchen with an irresistible aroma.
Step 8: Prepare the Vanilla Bean Mascarpone Frosting
While the Rhubarb Sticky Buns cool, prepare the frosting. In a mixing bowl, blend together 8 ounces of mascarpone cheese, 1/2 cup of powdered sugar, 1 tablespoon of vanilla bean paste, and 1/4 cup of heavy whipping cream. Whisk until smooth and creamy. The frosting should hold its shape yet remain spreadable, ready for luscious application on each warm bun.
Step 9: Frost and Serve
Once the buns have cooled for about 10 minutes, generously spread the vanilla bean mascarpone frosting over each sticky bun using a spatula or butter knife. The warm buns will help the frosting melt slightly, creating a delightful combination of creamy and tangy flavor. Serve your Rhubarb Sticky Buns warm for the best experience!

Storage Tips for Rhubarb Sticky Buns
Room Temperature: Keep your Rhubarb Sticky Buns in an airtight container for up to 3 days. Enjoy them fresh, warm, or at room temperature for a delightful treat!
Fridge: If you need to store them longer, place them in the fridge for up to a week. Just be aware that this may slightly change their texture.
Freezer: For longer storage, freeze the un-frosted buns in a single layer, then transfer to a freezer bag for up to 3 months. Thaw overnight in the fridge before frosting.
Reheating: To enjoy warm, simply reheat the buns in a microwave for about 15 seconds or in a preheated oven at 350°F for about 10 minutes.
Expert Tips for Rhubarb Sticky Buns
Well-Proofed Dough: Ensure your brioche dough doubles in size during each rise for maximum airiness and fluffy texture—don’t rush this step!
Fresh Ingredients: Use fresh rhubarb for the jam; it results in better flavor. If it’s too tart, adjust the sugar to balance out that tang!
Chill Your Butter: For the brioche, softened butter works best; if too warm, it can cause the dough to become greasy.
Watch the Baking Time: Keep an eye on the oven while baking—golden brown means they’re ready! Check a few minutes early to avoid overcooking.
Frosting Delight: Make the vanilla bean mascarpone frosting while the buns cool; it’s easier to spread when warm and enhances the flavors of the Rhubarb Sticky Buns.

The rhubarb quick jam can be made up to 3 days in advance and stored in the fridge, ensuring it retains its vibrant flavor.

Rhubarb Sticky Buns with Vanilla Bean Mascarpone Frosting Recipe FAQs
How do I choose ripe rhubarb for my sticky buns?
Absolutely! Look for rhubarb that is firm and brightly colored with no soft spots or dark spots all over. Fresh rhubarb should have vibrantly colored stalks—those are usually the best! Avoid any that appears wilted or has a dried-up appearance for the best flavor in your Rhubarb Sticky Buns.
What is the best way to store leftover sticky buns?
Very! Store your Rhubarb Sticky Buns in an airtight container at room temperature for up to 3 days. For longer storage, you can refrigerate them for up to a week—however, be alert that this might change their texture slightly. If you want some for later, freeze them without frosting up to 3 months.
Can I freeze my Rhubarb Sticky Buns?
Absolutely! After they have cooled, place the unfrosted buns in a single layer on a baking sheet to freeze them for about 1-2 hours. Once frozen solid, transfer them to a freezer bag, removing as much air as possible. They can be stored for up to 3 months. When you’re ready to enjoy, thaw overnight in the fridge and then frost!
What if my brioche dough doesn’t rise properly?
Lets troubleshoot! If your dough doesn’t rise, first ensure your yeast is fresh and active (it should puff up when mixed with warm milk). If the dough is too cold, let it rise in a warmer spot. Alternatively, if it rises too slowly, it could be due to too much flour; make sure to measure accurately! Kneading longer helps develop gluten for better structure, so don’t hesitate to knead for a bit more time if necessary!
Are these sticky buns safe for those with dietary allergies?
Great question! These Rhubarb Sticky Buns contain dairy and gluten, so if you’re preparing for anyone with milk or wheat allergies, it’s best to look for alternative recipes. You can try oat milk and a gluten-free flour blend if needed. However, keep a close watch on ingredients and cross-contamination based on individual dietary restrictions.
