Blueberry Custard Crumble Buns Ingredients
For the Dough
• All-Purpose Flour – Provides structure and body to the buns; consider bread flour for a chewier texture.
• Whole Milk – Activates yeast and adds richness; be sure to warm it to 100–110°F for best results.
• Active Dry Yeast – Essential for dough rise, creating fluffy air pockets; always check the expiration date for optimal performance.
• Granulated Sugar – Aids yeast activation and sweetens the dough; substitution with coconut sugar can lower the glycemic index.
• Egg – Acts as a binder to enrich the dough and gives a glossy finish when used for egg wash.
• Unsalted Butter – Adds flavor and tenderness; keep at room temperature for the dough, and melt for the crumble.
For the Custard Filling
• Cream Cheese – Ensures richness in the custard; allow it to soften at room temperature for easier mixing.
• Heavy Cream – Enhances the custard’s velvety texture, making it irresistible.
• Vanilla Extract – Provides depth to the custard flavor; don’t skip this for the best results!
• Powdered Sugar – Ensures a smooth and creamy filling consistency.
For the Blueberry Layer
• Blueberry Jam + Fresh Blueberries – Double the blueberry action for juicy texture and tartness; using fresh berries is recommended for optimal taste.

Step‑by‑Step Instructions for Blueberry Custard Crumble Buns
Step 1: Activate Yeast
Begin by warming whole milk to 100–110°F—ideal for activating active dry yeast. In a mixing bowl, combine the warm milk with the yeast and a tablespoon of granulated sugar. Stir gently and let the mixture sit for 5-10 minutes until it’s frothy and bubbly, indicating that your yeast is ready to work its magic in the Blueberry Custard Crumble Buns.
Step 2: Mix Dough
Once your yeast is activated, whisk together the remaining sugar and an egg into the yeast mixture. Gradually stir in the all-purpose flour and a pinch of salt until the dough begins to form. Turn it out onto a lightly floured surface and knead for 3–5 minutes, ensuring it’s smooth and slightly tacky but not sticky, which will set the foundation for your delicious buns.
Step 3: Incorporate Butter
Next, add the softened unsalted butter to the kneaded dough, working it in gradually until fully incorporated. Continue kneading until the dough is smooth and elastic, about another 3 minutes. This process helps achieve that tender crumb texture in the Blueberry Custard Crumble Buns, promising delightful bites filled with creamy custard.
Step 4: First Rise
Transfer your dough into a greased bowl, cover it with a damp cloth or plastic wrap, and place it in a warm area. Allow the dough to rise for 1–2 hours until it has doubled in size—this is the yeast doing its job! Keep an eye on it, as the ideal time will vary depending on the room temperature.
Step 5: Shape Buns
After the dough has risen, gently punch it down to release the air. Divide it into six equal pieces and shape each piece into a round ball. Flatten each ball into a 6-inch round on a parchment-lined baking sheet. These rounds will be the base for your Blueberry Custard Crumble Buns, ready for their delicious fillings!
Step 6: Prepare Custard Filling
In a mixer, beat the softened cream cheese until smooth and creamy. Gradually mix in the heavy cream, vanilla extract, and powdered sugar until the mixture is fluffy and well-combined. This custard filling is what makes these buns special; transfer it to a piping bag for easy filling in the next step.
Step 7: Fill & Top Buns
Brush each bun round lightly with egg wash for a golden finish once baked. Create an indent in the center of each bun using your fingers, and fill it generously with the creamy custard. Next, add a spoonful of blueberry jam and a few fresh blueberries on top, ensuring these buns are packed with flavor and ready for baking.
Step 8: Crumble Topping
In a bowl, combine melted butter, flour, brown sugar, and cinnamon until you achieve a crumbly texture. This crunchy topping is key to the Blueberry Custard Crumble Buns, providing a delightful contrast to the soft dough and creamy filling. Sprinkle the crumble generously over each filled bun to create a sweet, satisfying layer.
Step 9: Bake
Preheat your oven to 375°F. Once the oven is ready, place the baking sheet in and bake the buns for 20–25 minutes, or until they are puffed up and golden brown. The fragrant aroma will fill your kitchen, making it hard to resist the temptation to dive in right away!
Step 10: Cool & Dust
After baking, allow the Blueberry Custard Crumble Buns to cool on the baking sheet for about 10 minutes. Once cooled slightly, dust them with powdered sugar for an extra touch of sweetness and presentation. These charming buns are now ready to be served, perfect for any brunch or delightful dessert!

Blueberry Custard Crumble Buns Recipe FAQs
What kind of blueberries should I use for the best flavor?
Absolutely, fresh blueberries will give your Blueberry Custard Crumble Buns the best flavor! Look for berries that are plump and firm, with a deep blue color. Avoid those with dark spots or wrinkles, which indicate overripeness. If fresh blueberries aren’t available, you can use frozen ones; just remember to add them directly from the freezer to prevent excess moisture in your custard.
How do I store the buns for freshness?
You can keep your Blueberry Custard Crumble Buns in an airtight container at room temperature for up to 2 days. If you want them to last longer, pop them in the fridge where they will stay fresh for up to 4 days—just make sure they’re wrapped tightly! For the best flavor and texture, I recommend consuming them fresh.
Can I freeze the buns? How?
Yes, you can freeze Blueberry Custard Crumble Buns for up to 2 months! To do this, let the buns cool completely and then wrap each one individually in plastic wrap. For extra protection, place them in a freezer-safe bag or container. When you’re ready to enjoy them, thaw in the fridge overnight and reheat in a preheated oven at 300°F for 5-7 minutes to regain their delicious fluffiness.
What should I do if my yeast doesn’t activate?
If your yeast doesn’t activate, it could be due to the milk being too hot or not warm enough—aim for 100–110°F. Mix the activated yeast with a small amount of sugar in warm milk and wait for 5-10 minutes; it should get bubbly and frothy. If it doesn’t, the yeast might be expired, and it’s best to start over with fresh yeast to ensure your buns will rise perfectly!
Are these buns suitable for those with gluten allergies?
You can make gluten-free Blueberry Custard Crumble Buns by using a 1:1 gluten-free flour blend! While the texture may be slightly denser than traditional buns, it will still be delicious. Be cautious of cross-contamination if you’re baking for someone with celiac disease, and always check packaging for gluten-free certification.
Can I make these buns ahead of time?
Absolutely! You can prepare the dough and let it rise overnight in the fridge for a convenient morning bake. Just divide and shape the buns after the first rise, then cover and refrigerate instead of baking. In the morning, let them come to room temperature for about 30 minutes before applying the filling and crumble, then bake as directed. Enjoy the time saved in the morning!
