Oreo mini muffins

I made these for a girls night on Saturday and they were such a hit, they disappeared within minutes!  These are unbelievably moist, gooey, chocolatey and moreish!

Ingredients

8 oz self-raising flour

2 oz drinking chocolate powder

½ tsp salt

1 tsp baking powder

7 oz golden caster sugar

6 fl. oz milk

3 fl. oz sour cream

2 tsp vanilla essence

1 egg

2 oz margarine (plus extra for greasing)

15 Oreo cookies, smashed into small chunks

4 oz dark chocolate drops

For the icing

2 oz butter, at room temperature

10 oz icing sugar

4 oz cream cheese

2 tbsp sour cream

1 tsp vanilla essence

Method

1. Preheat the oven to 180°C. Melt the margarine and grease mini muffin tins (you’ll make about 36 mini muffins).
2. In large bowl, sift the flour, drinking chocolate, baking powder and salt, add the sugar and combine with a hand whisk.
3. In small bowl, combine the milk, sour cream, vanilla essence and egg.
4. Stir the egg mixture in to the flour mixture with the melted margarine until just combined.
5. Add the crushed cookies and chocolate drops, and gently stir into the cake batter.
6. Spoon the batter into the muffin tins, and bake for 15-20 mins or until cake-tester comes out clean. Leave to cool on a wire rack.
7. To make the icing, place the butter in an electric mixer and beat until smooth. 
8. Add the icing sugar and beat, then add the cream cheese, sour cream and vanilla and continue beating until light and fluffy.  Place in the fridge until ready to use.
9. Once the muffins are completely cool, spoon the icing into a piping bag with a medium-sized nozzle and pipe onto each muffin.
10. Crush the remaining Oreos to the size of fine breadcrumbs, and sprinkle over the top of the muffins.
