Directions

1. Combine the brown sugar, flour, cocoa powder, egg, oil, baking powder, vanilla, and a pinch of salt. Mix until the dough is thick but crumbly.
2. Preheat the oven to 170 degrees Celsius.
3. Butter and flour a 22-centimeter springform pan.
4. Divide the dough into two parts.
5. Place one part of the dough in the springform pan and press it to even it out.
6. Add a layer of orange jam, spreading it even all across the dough, but keeping it 1 centimeter from the sides of the pan.
7. Cover with the remaining dough and bake for 30 minutes.
8. Serve cold or at room temperature, sprinkled with powdered sugar.
