Ingredients
Scale
- 3 tablespoons creamy peanut butter
- 2 tablespoons granulated sugar
- 4 tablespoons all-purpose flour
- 1/4 teaspoon baking powder
- 1 large egg
Instructions
- In a microwave-safe mug, add 4 tablespoons (32 g) of all-purpose flour, 2 tablespoons (25 g) of granulated sugar, and 1/4 teaspoon (1 g) of baking powder. Mix evenly with a fork or small whisk.
- Add 3 tablespoons (48 g) of creamy peanut butter to the mug. Stir well to combine with the dry ingredients, ensuring no large clumps remain.
- Crack 1 large egg (about 50 g) into the mug and mix thoroughly until smooth and well incorporated.
- Optional: Add a splash of vanilla extract (1/4 teaspoon) or a pinch of salt to enhance flavor and stir again.
- Microwave on high for 70-90 seconds. Start checking at 70 seconds to avoid overcooking. The cake should rise and look set but remain soft in the center.
- Check doneness by inserting a toothpick or fork in the center; if it comes out mostly clean with a few moist crumbs, it is done. If wet batter remains, microwave in 10-second bursts.
- Let the mug cake cool for 1-2 minutes before eating. Optionally top with honey, chocolate chips, or whipped cream.
Notes
Use natural creamy peanut butter for best flavor and texture. Avoid overcooking to prevent a rubbery texture. Stir well before microwaving to ensure even rising and avoid dense flour pockets. For gluten-free, substitute almond flour. For vegan, use a flax egg and vegan peanut butter.
