Walnut Streusel Coffee Cake Draft

How I make it

Topping and filling

1. Preheat the oven to 340°F (170°C) and grease a baking pan.

2. Pulse the walnuts, cinnamon and brown sugar in a food processor.

3. Set aside 3/4 cup of the mixture for the filling.

4. Add the flour and butter to the rest and process until clumpy. Cover and refrigerate.

Batter and assembly

1. In a bowl, mix the egg yolks and cream.

2. In a stand mixer, mix the flour, sugar, salt and baking powder.

3. Add the crème fraîche and melted butter and mix on low speed until smooth.

4. Add the yolk-cream mixture and keep mixing.

5. Spread a third of the batter in the pan and sprinkle the filling over it.

6. Cover with the rest of the batter, smooth the top and scatter the walnut crumbs over it.

7. Bake for about 50 minutes, until golden.
