- Category: Dessert
- Cuisine: American
Ingredients
- 4 tablespoons (30 g) all-purpose flour
- 3 tablespoons (38 g) granulated sugar
- 2 tablespoons (10 g) unsweetened cocoa powder
- Pinch of salt
- 1/8 teaspoon baking powder
- 3 tablespoons (45 ml) milk (whole milk preferred, or any dairy-free alternative)
- 2 tablespoons (30 ml) vegetable oil (or melted coconut oil)
- 1/4 teaspoon vanilla extract
- 1 tablespoon (16 g) peanut butter (room temperature, creamy or chunky)
Instructions
- In a microwave-safe mug, whisk together the flour, sugar, cocoa powder, salt, and baking powder until evenly combined with no lumps.
- Add the milk, vegetable oil, and vanilla extract to the mug and stir gently until smooth and thick but pourable.
- Spoon the peanut butter into the center of the batter without stirring it in.
- Microwave on high for 45 to 60 seconds, starting to check at 45 seconds. The edges should be set but the center slightly wet.
- Let the mug brownie rest for one minute to finish cooking and allow the peanut butter center to stay gooey.
- Enjoy directly from the mug, optionally topped with vanilla ice cream or powdered sugar.
Notes
Use a larger mug to prevent overflow and microwave in short bursts to avoid overcooking. For a gooey peanut butter center, do not stir the peanut butter into the batter. Let the brownie rest after microwaving to firm up the edges while keeping the center molten. Chilling peanut butter slightly before adding can help prevent it from sinking too much. Variations include swapping peanut butter for other nut butters or using dairy-free milk and coconut oil for vegan adaptation.
