Tips & Variations
- Underbaking slightly keeps the brownie soft and gooey; adjust timing based on your microwave’s power.
- Swap brown sugar for white sugar if desired, but brown sugar adds a richer flavor.
- Add a pinch of cinnamon or a splash of vanilla extract to enhance the flavor profile.
- For a nutty twist, sprinkle chopped walnuts or pecans on top before microwaving.
Storage
This mug brownie is best enjoyed fresh and warm. If you have leftovers, cover and refrigerate for up to 2 days. Reheat in the microwave for 15–20 seconds before serving, though the texture may be firmer than freshly made.

FAQs
Can I use regular vinegar in this recipe?
Yes, white vinegar or apple cider vinegar works well. It helps react with the baking soda to create a light texture.
What if I don’t have a microwave?
This recipe is designed for the microwave. To bake it in a conventional oven, transfer the batter to a small oven-safe dish and bake at 350°F (175°C) for about 15-20 minutes, checking doneness regularly.

Ingredients
Dry Ingredients
- 2 tbsp cocoa powder
- 1/4 cup all-purpose flour
- 1/2 tsp baking soda
- Pinch of salt
- 3 tbsp brown sugar
Wet Ingredients
- 3 tbsp melted butter
- 3 tbsp milk
- 1/2 tsp vinegar
Add-ins
- 1 tbsp chocolate chips
To Serve
- Vanilla ice cream (optional)
Instructions
- Mix Dry Ingredients: In the microwave-safe mug you will use for baking, combine the cocoa powder, flour, baking soda, salt, and brown sugar. Stir well to evenly distribute all dry ingredients.
- Add Wet Ingredients: Pour in the melted butter, milk, and vinegar to the dry ingredients in the mug. Mix thoroughly until the batter is smooth and fully combined.
- Add Chocolate Chips: Stir in the chocolate chips evenly into the batter to add extra gooey chocolate pockets in your brownie.
- Microwave Bake: Place the mug in the microwave and cook on the regular heating setting for 1 minute. Carefully check the brownie’s doneness; it should be slightly underbaked inside.
- Continue Baking: If needed, continue microwaving in 30-second intervals up to two more times (totalling about 2 minutes) until the brownie is just cooked but still moist and fudgy.
- Serve: It’s best to serve the brownie hot and slightly underbaked for a soft center. Top with vanilla ice cream or whipped cream to elevate the dessert.
Notes
- Microwave wattages vary. Adjust cooking time accordingly to avoid overcooking.
- Underbaking slightly gives the best fudgy texture for the mug cake.
- Serve immediately for the best taste and texture as microwaved brownies can become dense when cooled.
- You can substitute brown sugar with white sugar or coconut sugar.
- For a dairy-free option, use a plant-based milk and vegan butter.
