Blueberry & Custard Brioche Bun with Crumble

Ingredients List

  • 500g brioche dough (store-bought or homemade)
  • 200g fresh or frozen blueberries (thawed if using frozen)
  • 250ml custard (prepared and cooled)
  • 100g unsalted butter (softened for crumble)
  • 100g all-purpose flour (for crumble topping)
  • 50g granulated sugar (for crumble topping)
  • 1 egg (beaten, for egg wash on buns)

How to Prepare the Blueberry & Custard Brioche Bun with Crumble

Alright, let’s dive into the wonderful world of making these Blueberry & Custard Brioche Buns with Crumble! It’s a delightful process that fills your kitchen with the sweetest aromas. Follow these steps, and you’ll have a batch of buns that will impress everyone!

Prepping the Dough

First things first, you want to get that brioche dough ready. If you’re using store-bought dough, just let it come to room temperature for about 15 minutes. This makes it easier to work with. Roll it out on a lightly floured surface until it’s about half an inch thick. Then, grab a round cutter or a glass and cut out circles—around 10 cm in diameter works perfectly. Don’t worry if the dough sticks a bit; just sprinkle a little more flour and keep rolling. It’s all about being gentle with it!

Filling the Buns

Now for the fun part—filling those dough circles! Take a spoonful of cooled custard and a few blueberries, and place them in the center of each circle. Be careful not to overfill them; about a tablespoon of custard and a couple of berries should do the trick. When you fold the dough over the filling, pinch the edges tightly to seal them up. This is crucial to keep that delicious filling from spilling out while baking—trust me, you don’t want to miss out on any of that custardy goodness!

Making the Crumble Topping

Let’s whip up that crumble topping! In a mixing bowl, combine the softened butter, flour, and sugar. Use your fingers to mix them together until you get a crumbly texture that resembles small pebbles. It should feel a bit sandy but still hold together when pressed. This crumble is what brings that extra crunch to your buns, and it’s oh-so-delicious!

Baking the Buns

Time to bake these beauties! Place your filled buns on a baking sheet lined with parchment paper, giving them a little space to rise. Brush the tops with the egg wash for that golden, glossy finish. Now, sprinkle the crumble generously over each bun. Pop them in a preheated oven at 180°C (350°F) and bake for about 20-25 minutes. You’ll know they’re done when they’re golden brown and your kitchen smells like a bakery! Let them cool for a few minutes before serving. Enjoy every bite of this delightful treat!

Tips for Success

Lastly, keep an eye on the baking time; every oven is different, so check for that golden brown color. Trust me, taking these little steps will elevate your buns to bakery-level perfection!
