Instructions

  1. Step 1: In a microwave-safe mug, add 4 tbsp all-purpose flour, 3 tbsp granulated sugar, 1 tbsp unsweetened cocoa powder, and 1/4 tsp baking powder. Stir to combine dry ingredients.
  2. Step 2: Add 3 tbsp milk, 2 tbsp vegetable oil, and 1/4 tsp vanilla extract to the mug. Stir well until the batter is smooth and free of lumps.
  3. Step 3: Microwave on high for 90 seconds. Check the cake’s doneness by inserting a toothpick into the center; it should come out clean.
  4. Step 4: Allow the mug cake to cool for 2 minutes before eating straight from the mug or turning out onto a plate.
