¼ cup all-purpose flour
2 tablespoon light brown sugar (packed)
¼ teaspoon baking powder
1 pinch salt
3 tablespoon milk
3 tablespoon butter (melted)
½ teaspoon vanilla extract
2 tablespoon chocolate chips (milk chocolate or semi-sweet chocolate morsels, mini chips are best)
Instructions
Whisk together your dry ingredients (¼ cup all-purpose flour, 2 tablespoon light brown sugar, ¼ teaspoon baking powder, and 1 pinch salt) either directly in your mug or in a small bowl.
Stir in the liquid ingredients (3 tablespoon milk, 3 tablespoon melted butter, and ½ teaspoon vanilla extract), mix until smooth, then fold in the 2 tablespoon chocolate chips. Transfer the batter into a mug if needed.
Microwave on high for 1-2 minutes. Continue heating in 15-30 second increments if needed until the cake is puffy, set, and springs back to the touch.
Allow your cooked microwave mug cake to sit in the microwave for 1 minute before serving.
