Ingredients
Quantities are shown as originally provided.
- 2 tablespoons unsalted butter (melted (or vegetable oil))
- 1½ tablespoons milk (dairy or non-dairy)
- 1 large egg yolk
- ½ teaspoon pure vanilla extract
- 2 tablespoons granulated sugar
- 3 tablespoons super-fine blanched almond flour
- 2½ tablespoons gluten-free oat flour
- 3/8 teaspoon baking powder
- Optional: 1 tablespoon sprinkles
- Optional for serving: Powdered sugar, whipped cream, and/or ice cream
Instructions
- 1
In a 12-ounce or larger mug, whisk together all the wet ingredients: oil or melted butter, milk, egg yolk, and vanilla extract. For a cleaner appearance, you can whisk together the cake batter in a separate bowl and then pour it into the mug to cook, or for fewer dishes, whisk it directly in the mug.

Add the dry ingredients and whisk until completely smooth. If you mixed the batter up in a separate bowl, pour it into the mug. Fold in any mix-ins of your choice that you want to be dispersed throughout the batter: sprinkles, nuts, fruit, etc. For add-ins such as chopped chocolate, peanut butter, nutella, or edible cookie dough, dollop these on top without mixing.

Microwave on high. For each cake, start at 1 minute, then add 15 seconds at a time until fully baked. Microwave 1½-3 minutes (on my microwave, it takes exactly 2 minutes 30 seconds). Let cool 2-3 minutes and serve with your favorite toppings, such as whipped cream or ice cream!
