What You Need to Make the Perfect Brownie in a Mug
Before you start, gather the following ingredients and tools:
Ingredients:
- 3 tbsp all-purpose flour
- 2 tbsp unsweetened cocoa powder
- 3 tbsp granulated sugar
- 1/8 tsp baking powder
- Pinch of salt
- 3 tbsp milk
- 2 tbsp vegetable oil (or melted butter)
- 1/4 tsp vanilla extract
- 2 tbsp chocolate chips (optional, for extra gooeyness)
Tools:
- Microwave-safe mug
- Spoon or small whisk
- Microwave
This recipe is perfect for anyone who loves chocolate and wants a quick, single-serving dessert without all the hassle of baking a full batch of brownies.
Step-by-Step Instructions to Make Your Brownie in a Mug
Step 1: Mix the Dry Ingredients
In your microwave-safe mug, add 3 tbsp of all-purpose flour, 2 tbsp of unsweetened cocoa powder, 3 tbsp of granulated sugar, 1/8 tsp of baking powder, and a pinch of salt. Use a spoon or small whisk to mix these dry ingredients together until they are well-combined.
Step 2: Add the Wet Ingredients
To the dry mixture, add 3 tbsp of milk, 2 tbsp of vegetable oil (or melted butter), and 1/4 tsp of vanilla extract. Stir everything together until the batter is smooth and free of lumps.
Step 3: Optional – Add Chocolate Chips
For an extra indulgent treat, mix in 2 tbsp of chocolate chips. This will give your brownie a gooey, melt-in-your-mouth texture.
Step 4: Microwave and Enjoy
Place the mug in the microwave and cook on high for 1 minute and 30 seconds. You’ll see the brownie rise and firm up, but it should still be soft and fudgy in the middle. If you prefer a more cooked texture, microwave it for an additional 10-15 seconds, but be careful not to overcook.
Step 5: Cool and Serve
Let the brownie cool for a minute before diving in. You can enjoy it as-is, or top it with a scoop of ice cream, a dollop of whipped cream, or even some extra chocolate syrup. For a rich and decadent treat, make my White Chocolate Raspberry Cupcakes Recipe.

Tips for Making the Best Mug Brownie
Avoid Overcooking
Microwaves vary in power, so cooking times may differ. If your mug brownie seems a little too wet after 1 minute and 30 seconds, give it another 10-15 seconds. Be careful not to overcook it, as this will make the brownie dry and less enjoyable.
Use the Right Mug
Make sure to use a microwave-safe mug with a wide enough surface area to allow the brownie to rise without spilling over. A 12 oz mug works best for this recipe.
Top It Off
For a decadent finish, top your brownie with a scoop of vanilla ice cream or a dollop of whipped cream. You can also drizzle extra chocolate sauce or add a sprinkle of powdered sugar for extra sweetness.
Customize Your Flavor
Try adding different mix-ins like nuts (walnuts, pecans, or almonds), or a tablespoon of peanut butter for a unique twist on this classic recipe.
