I made this Vegan Peanut Butter Mug Cake for my family’s Sunday brunch last month. The peanut butter stayed gooey in the middle, and my nephew loved it.
Quick Vegan Peanut Butter Mug Cake

This mug cake features a rich peanut butter flavor with a soft and gooey center. It cooks in the microwave in about a minute, making it an easy dessert option for one or two people who want something sweet without much effort.
Ingredients
- 3 tablespoons all-purpose flour
- 2 tablespoons peanut butter
- 2 tablespoons maple syrup or agave nectar
- 1/4 teaspoon baking powder
- 1/4 teaspoon vanilla extract
- 2 tablespoons almond milk or any plant-based milk
- Pinch of salt
- Optional: dark chocolate chips or chopped nuts for added texture
Instructions
- Combine Dry Ingredients: In a microwave-safe mug, whisk together the flour, baking powder, and salt.
- Mix in Peanut Butter: Add the peanut butter and maple syrup to the dry ingredients, mixing well until combined.
- Add Wet Ingredients: Stir in the almond milk and vanilla extract until smooth. For a richer texture, fold in chocolate chips or nuts if desired.
- Microwave: Place the mug in the microwave and cook on high for 60-90 seconds, or until the cake has risen and is set in the middle. Be cautious not to overcook, as it will continue to cook slightly after removal.
- Cool Slightly: Let the mug cake cool for a minute so the center can settle before enjoying.
