Ingredients
- 2 1/2 tbsp Dutch process cocoa powder
- 1 1/2 tbsp all-purpose flour
- 2 tbsp granulated white sugar
- 2 tbsp oil (canola, vegetable, or olive oil)
- 2 tbsp water
- 1 1/2 tbsp chopped dark chocolate
Instructions
- Step 1: In an 8 oz microwave-safe mug, combine the cocoa powder, flour, and sugar. Whisk them together using a mini whisk until evenly mixed.
- Step 2: Add the oil and water to the mug. Whisk briskly until the batter is smooth and free of lumps from the cocoa or flour.
- Step 3: Stir half the chopped dark chocolate into the batter. Then sprinkle the remaining chocolate pieces on top of the batter.
- Step 4: Microwave on full power for about 40 seconds (adjust time depending on your microwave wattage). The brownie top should no longer look wet but might still be slightly moist.
- Step 5: Let the brownie cool for a few minutes before digging in. Enjoy it warm for the best fudgy texture.
Tips & Variations
- Use bittersweet or milk chocolate depending on your preferred sweetness level.
- Try adding a pinch of instant coffee powder to intensify the chocolate flavor.
- Swap water for milk or a non-dairy alternative for a slightly creamier texture.
- For a nutty crunch, mix in chopped nuts before microwaving.
Storage
This mug brownie is best enjoyed immediately but can be stored in an airtight container in the refrigerator for up to two days. Reheat gently in the microwave for about 15 seconds to restore warmth and softness.

FAQs
Can I use regular cocoa powder instead of Dutch process?
Yes, but the flavor will be slightly different. Dutch process cocoa is smoother and less acidic, resulting in a richer taste.
What if my microwave is more or less powerful than 1000 watts?
Adjust the cooking time in 5-second increments. If your microwave is stronger, reduce the time slightly; if weaker, add a few seconds until the brownie sets but remains moist.

Ingredients
Dry Ingredients
- 2 1/2 tbsp Dutch process cocoa powder
- 1 1/2 tbsp all-purpose flour
- 2 tbsp granulated white sugar
Wet Ingredients
- 2 tbsp oil (canola, vegetable, or olive oil)
- 2 tbsp water
Add-ins
- 1 1/2 tbsp chopped dark chocolate
Instructions
- Mix Dry Ingredients: In an 8 oz microwave-safe mug, combine the cocoa powder, all-purpose flour, and sugar. Whisk these together with a mini whisk until evenly mixed.
- Add Wet Ingredients: Pour in the oil and water to the dry mixture. Whisk briskly and thoroughly to achieve a smooth batter, breaking up any lumps of cocoa powder or flour for a consistent texture.
- Incorporate Chocolate: Add half of the chopped dark chocolate into the batter and stir briefly to distribute, then sprinkle the remaining chocolate chunks evenly on top of the batter for a melty chocolate topping.
- Microwave Cooking: Cook the mug brownie on full power in the microwave for about 40 seconds (adjust timing based on the wattage of your microwave). The top should appear set and no longer wet, though it might remain a bit moist inside.
- Cooling and Serving: Let the brownie cool for a few minutes in the mug; this allows it to set up slightly and makes it easier to eat while warm and fudgy.
Notes
- Microwave wattage varies; if using a lower wattage microwave, increase cooking time slightly and vice versa.
- Use a microwave-safe mug of about 8 oz capacity to avoid overflow during cooking.
- You can substitute chopped chocolate with chocolate chips or chunks for a similar effect.
- For a richer taste, try using olive oil instead of neutral oil.
- Enjoy the brownie warm for the best fudgy texture; reheating may dry it out.
