Ingredients for Vanilla Mug Cake

Dry Ingredients: All-purpose flour, cornstarch, and baking powder are added for the right texture, structure, and flavor.

Wet Ingredients: Sugar and butter bring a moist and sweet flavor and the milk adds creaminess. For the best vanilla flavor, use pure vanilla extract, Mexican vanilla extract, or vanilla paste.

Add-Ins: Anything can be mixed into a mug cake! We like chocolate chips or peanut butter chips, crushed cookies or toffee pieces, chopped nuts, and coconut as mix-ins.

Toppings: Top vanilla mug cakes with sprinkles, a scoop of ice cream, whipped cream, or even homemade granola. Or try a spoonful of frosting.

  2. Melt butter in the mug in the microwave and then stir in the remaining ingredients.
  3. Stir the dry ingredients into the wet ingredients until smooth.
