Apple-Gouda Muffin

Preheat the oven to 160°C (fan) and grease a muffin tin (without paper liners).

Coarsely grate the Gouda and cut the apple into small cubes.

Mix flour, baking powder, baking soda, oats, allspice and salt in a bowl.

Add the grated Gouda and apple cubes to the dry ingredients and mix well.

In a second bowl, whisk the egg, oil, quark and buttermilk until frothy.

Fold the flour mixture into the quark–buttermilk mixture only briefly until just combined into a batter.

Spoon the batter into the greased wells and bake for 20–25 minutes.

Let the muffins rest in the tin for 5 minutes, then carefully remove and serve while still warm.
