Cannelés
Preheat oven to 180°C.
Mix flour, parmesan and baking powder in a bowl. Reserve.
In a second bowl, mix yogurt, pesto and egg.
Pour the preparation in the first recipient on top of flour and mix until you get a homogeneous paste. This mix will be quite thick but this is normal.
Butter and half fill your mini-cannelé molds.
Bake for 17 minutes.
If you are using silicone mould, unmold straight away.
