M&M Muffin

Preheat the oven to 160 °C (fan) and line a muffin tin with liners.

Mix the flour, baking powder and baking soda in a bowl, then fold in the M&M's and chopped peanuts.

In a second bowl, beat the egg, sugar, oil and buttermilk until frothy.

Add the flour mixture to the buttermilk mixture and fold in briefly until no dry flour remains.

Fill the batter into the liners and, if desired, sprinkle with the reserved M&M's and peanuts.

Bake for about 20–25 minutes, then let rest for 5 minutes, remove from the tin and cool completely on a wire rack.
