Just a quick one, adapted to use up stuff in my fridge!

220g flour
2 tbsp. cocoa powder
½ tsp. baking soda
2 tsps. baking powder
200g white sugar
50g chopped hazelnuts
200ml fresh milk
100g margarine
1 egg
1 tsp. pure vanilla essence

Sift dry ingredients into a bowl. Melt marg (just) and wait to cool but still liquid. Beat egg and add to marg with milk and vanilla. Stir into dry ingredients. Put in muffin cases, bake for 20mins (ish – check!) at 200 degrees centigrade. They came out delicious!
