Vanilla mug cake is a light and moist vanilla cake made in a mug. This vanilla microwave cake can be made in a fewminutes. Top this cake mug cake with frosting and sprinkles.
Stir in the flour until smooth and well combined. If you would like to add sprinkles or any other mix in, do so now. I like to mix a few sprinkles in and also top the vanilla cake batter with a few more.
Make the buttercream while the cake cools. Just like with regular cake, the vanilla cake in a mug needs time to cool if you’re going to top with frosting. Mix room temperature butter in a bowl until smooth. Mix in the powdered sugar and milk until smooth and well combined.
