How to make
The eggs are whisked, add sugar and yoghurt. Gradually add the flour with the baking powder and cocoa. Blend well with a mixer, add the oil.
The pears are pureed separately and mixed with the mixture, then add the ground walnuts. Add finely crushed chocolate bits to the blend. Distribute into muffin forms, covered with greased baking paper.
Bake in a moderate oven until they rise and crack.
