Mug_Cake
4 tbsp flour
4 tbsp sugar
2 tbsp cocoa powder
1/8 tsp baking powder
1/8 tsp salt
4 tbsp milk
2 tbsp oil
1/4 tsp vanilla extract
Mix all the ingredients together in a coffee mug and microwave on high power for 2 minutes.
I often divide the batter into four ramekins (9 cm in diameter) and bake each one in the microwave for 40 seconds on high power.
