Coca-Cola Muffin 2

Preheat the oven to 160 °C (fan) and prepare a muffin tin lined with paper cases.

Grate the chocolate and mix it in a bowl with the flour, baking powder, cinnamon and the chopped walnuts.

In a second bowl, beat the egg, sugar, oil, Coca-Cola and buttermilk briefly until frothy.

Add the flour mixture to the wet ingredients and fold in only until no dry flour remains.

Divide the batter among the paper cases, filling them about two-thirds full.

Bake the muffins for about 20–25 minutes and remove them as soon as a skewer comes out clean.

Let the muffins rest for 5 minutes, then remove them from the tin and cool completely on a wire rack.

If desired, mix 60 g powdered sugar with 1–2 tbsp of cola to make a glaze, spread it over the muffins and decorate with a cola-bottle gummy.
