Warm rhubarb buns topped with crunchy walnuts

 
Golden baked rhubarb crumble buns topped with chopped walnuts and melting butter pieces in a black baking tray.
 

Sweet, buttery, crumbly… and filled with cozy homemade flavor.

There’s something really comforting about recipes like this.
Soft bread rolls soaked in warm vanilla milk, layered with jam, tangy rhubarb filling, crunchy walnuts, and baked until golden with little melting pieces of butter on top. It’s the kind of dessert that feels old-fashioned in the best possible way — simple ingredients, warm kitchen smells, and a tray that disappears way too quickly.

The slightly tart rhubarb balances the sweetness perfectly, while the toasted walnut topping gives these buns a bakery-style finish without needing complicated steps. Perfect for breakfast, dessert, or a cozy afternoon coffee break.

📝Ingredients

  • 4 bread rolls (buns)
  • About 2 cups milk
  • 1 egg
  • 1 packet vanilla sugar
  • 4 tablespoons granulated sugar
  • 4 tablespoons apricot jam
  • 1 batch cooked rhubarb filling
  • 100g chopped walnuts
  • 30g butter

🥄 Instructions

1. Cut the bread rolls in half.
2. In a metal bowl or saucepan, whisk together the egg, vanilla sugar, and granulated sugar until smooth.
3. Pour in the milk and warm the mixture slightly. Do not boil it — just warm enough to help the sugar dissolve.
4. Dip the bottom halves of the buns into the warm milk mixture and let them soak briefly so they absorb some of the liquid.
5. Place the soaked halves onto a baking tray lined with parchment paper.
6. Spread apricot jam over each piece.
7. Sprinkle some of the chopped walnuts on top.
8. Spoon the cooked rhubarb filling over the buns.
9. Cover with the soaked top halves of the buns.
10. Brush the tops lightly with egg white.
11. Sprinkle with the remaining chopped walnuts and place small pieces of butter on top.
12. Bake in an air fryer oven or convection oven at 180°C (350°F) for about 15 minutes, until golden and slightly crisp on top.
Serve warm and enjoy 😊

⚠️ Troubleshooting (real fixes)

If something feels off the first time, this is usually why… 🛠️
Click a common problem to see how to fix it.

❌ My buns became too soggy
Most likely

The buns probably soaked too long in the milk mixture. A quick dip is enough — they should absorb flavor without falling apart.

Fix
  • Dip the buns only for a few seconds
  • Use slightly firmer or day-old buns
❌ The filling leaked out while baking
Most likely

Too much filling can make the buns slide apart in the oven.

Fix
  • Use a slightly thinner layer of rhubarb filling
  • Do not overfill the buns
  • Press the top bun gently before baking
