Instructions

1

Dissolve a spoonful of sugar in the lukewarm milk and sprinkle the yeast on top. Let it sit for 10 minutes until foamy.

Tip: Yeast feeds on sugar and produces carbon dioxide, creating the bubbles in the dough.
2

Sift the flour into a bowl, add salt, egg, remaining sugar, melted (not hot!) butter, and the foamy yeast mixture.

Tip: Fat coats the gluten strands, making the dough fluffy rather than bread-like.
3

Knead for 10 minutes until smooth and elastic. Cover and let rise in a warm place for 45-60 minutes (until doubled).

Tip: Kneading develops the gluten structure that traps the gas bubbles.
4

Roll out to a rectangle (approx. 1/4 inch thick). Brush generously with melted butter and dust with the cocoa powder mixed with powdered sugar.

Tip: The butter creates a barrier so the layers remain distinct.
5

Roll up tightly like a jelly roll and cut into 1-inch slices. Place on a baking sheet (leave space!) and let rest for another 15 minutes.

Tip: The second proofing is essential for them to be soft and not crack.
6

Bake at 350°F (180°C) for 20 minutes until golden. Dust with powdered sugar while hot.

Tip: Don't dry them out! Cocoa filling burns easily, check the bottoms.

Recipe FAQ

Why didn't the dough rise?
Either the milk was too hot (killed the yeast) or the room was too cold. Yeast loves 77-86°F (25-30°C).
The buns are dry. Why?
Don't overbake! Remove them as soon as they are golden. Also, the amount of butter spread under the filling matters.
