This classic Easy Vanilla Mug Cake recipe is easy to make, full of vanilla flavor, and is great served warm with whipped cream or ice cream over the top.
In a small bowl, whisk the flour, baking powder, and salt together.
In a 2 cup measuring cup, whisk the sugar, butter, milk, egg, and vanilla together until well combined.
Add the butter mixture to the flour mixture and whisk until the batter is smooth.
Pour batter into a 10-ounce coffee mug.
Microwave, one at a time, on high for 90 seconds. (Every microwave is different. If the cake hasn't set, microwave in 10-second intervals until cooked through.) Let the cakes stand for 2 minutes.
Top with whipped cream and berries or other desired topping. Enjoy!
Notes
Because this cake is "baked" in the microwave, you're not going to get exactly the same results as a cake baked in the oven. This mug cake is slightly spongy.
