Description

A quick and easy microwave mug brownie recipe that delivers a rich, fudgy texture in just 90 seconds, perfect for a personal-sized chocolate treat.

Ingredients

Scale

4 tablespoons (32 grams) all-purpose flour
4 tablespoons (50 grams) granulated sugar
2 tablespoons (15 grams) unsweetened cocoa powder (preferably Dutch-processed)
A pinch of salt
1/8 teaspoon baking powder
2 tablespoons (30 ml) vegetable oil or melted butter
3 tablespoons (45 ml) water
1/4 teaspoon vanilla extract
1/4 teaspoon instant coffee powder (optional)

Instructions

In a microwave-safe mug, combine 4 tablespoons all-purpose flour, 4 tablespoons granulated sugar, 2 tablespoons unsweetened cocoa powder, a pinch of salt, 1/8 teaspoon baking powder, and 1/4 teaspoon instant coffee powder if using. Stir well until evenly mixed (about 1-2 minutes).
Add 2 tablespoons vegetable oil or melted butter, 3 tablespoons water, and 1/4 teaspoon vanilla extract. Stir thoroughly until smooth and thick with no dry flour pockets (about 1 minute).
Microwave the mug on high for 90 seconds. Adjust time by 10-15 seconds if needed depending on microwave wattage. The top should look set but still moist.
Carefully remove the mug and let the brownie cool for about 2 minutes to set and avoid being too hot or gooey.
Optional: Before microwaving, sprinkle chocolate chips, chopped nuts, or a pinch of sea salt on top for added texture and flavor.

Notes

Use a ceramic mug with a wider base to prevent burnt spots and overflow. Adjust microwave time based on your microwave’s power. For dairy-free, substitute butter with coconut or almond oil. For gluten-free, use a 1:1 gluten-free baking flour blend. Coffee powder enhances chocolate flavor but is optional.
