Three Chocolate and Yogurt Muffins

Preheat the oven to 180°C (170°C if fan-assisted).

In a bowl, mix the flour, cocoa, sugar, baking powder, and salt.

In another bowl, combine the yogurt, oil, eggs, and milk, mixing well.

Incorporate the liquid ingredients into the dry ones, stirring until you get a smooth mixture.

Add the chocolate chips and mix gently.

Pour the mixture into muffin molds, filling them 3/4 full.

Distribute the dark, milk, and white chocolate pieces on the surface of each muffin.

Bake for 25 minutes or until a toothpick inserted in the center comes out clean.

Let cool before serving.
