Description
A quick, 4-ingredient budget-friendly dessert that combines a fudgy chocolate brownie base with a creamy peanut butter swirl, ready in just 5 minutes.
Ingredients
Scale
- 4 tablespoons all-purpose flour
- 3 tablespoons granulated sugar
- 2 tablespoons unsweetened cocoa powder
- 3 tablespoons milk
- 2 tablespoons vegetable oil or melted butter
- 1/2 teaspoon vanilla extract
- 1 pinch salt
- 1 tablespoon creamy peanut butter
- 1 teaspoon powdered sugar (optional, if peanut butter is unsweetened)
Instructions
- In a small mixing bowl or directly in a large microwave-safe mug, whisk together the flour, sugar, cocoa powder, and salt until no lumps remain.
- Add the milk, oil (or melted butter), and vanilla extract to the dry ingredients. Stir vigorously until a smooth, thick batter forms resembling chocolate pudding.
- Microwave the mug on high for 1 minute. Check the top; it should look set but not wet. If still liquidy, microwave for another 30 seconds. Do not overcook.
- Remove the mug from the microwave. Immediately drop a spoonful of creamy peanut butter onto the center of the brownie.
- Using the tip of a knife or spoon, gently drag through the peanut butter and into the batter to create a swirl pattern.
- Microwave the mug again for 30 seconds to melt the peanut butter slightly and create a gooey swirl effect.
- Let the brownie sit for 2 minutes to cool and set before eating directly from the mug.
Notes
Use a large mug to prevent overflow. Microwaves vary in power, so start with 1 minute and check frequently. The brownie continues to cook slightly after removal due to residual heat. For extra fudginess, add a square of chocolate before the final microwave. Store leftovers in an airtight container for up to 2 days, though best served fresh.
