Ricotta and Chocolate Crumble Cake

Method

1. In a blender, combine flour, cold butter, sugar, baking powder, a pinch of salt, and orange zest. Blend until the mixture resembles sandy crumbs.
2. Add the eggs and blend again until larger crumbs form.
3. Transfer the crumbs to a bowl and mix in the chocolate chips by hand, further breaking up the dough.
4. Set the crumb mixture aside.
5. Without cleaning the blender, add ricotta, icing sugar, cinnamon, and orange juice. Blend until smooth.
6. Line a baking pan with parchment paper. Place about two-thirds of the crumb mixture into the pan, pressing it into the bottom and up the sides to form a crust.
7. Pour the ricotta cream over the crust and spread evenly.
8. Cover with the remaining crumb mixture.
9. Bake at 200°C (400°F) on the middle rack for 25 minutes. Then move the pan to the bottom rack and bake for another 10–15 minutes.
10. Let cool slightly, then serve.
