Instructions

Step 1: In a microwave-safe 12 oz mug, whisk together 4 tbsp all-purpose flour, 4 tbsp granulated sugar, and 1/4 tsp baking powder until well combined.
Step 2: Add 3 tbsp whole milk, 2 tbsp vegetable oil, and 1/4 tsp vanilla extract to the mug and whisk until smooth and free of lumps.

Step 4: In a small bowl, mix 3 tbsp evaporated milk, 3 tbsp sweetened condensed milk, and 3 tbsp heavy cream until smooth.
Step 5: Using a fork or skewer, poke several holes in the top of the cake in the mug, then pour the milk mixture evenly over the cake, allowing it to soak in.
