Step-by-Step Instructions
Step 1: Choose the Right Mug

A slightly larger mug prevents the batter from overflowing during cooking.
Step 2: Mix the Dry Ingredients
Add the following to the mug:

Stir with a fork until the mixture looks evenly combined.
Tip: Breaking up cocoa powder lumps ensures a smooth brownie texture.
Step 3: Add the Wet Ingredients
Pour in:
- Milk
- Vegetable oil or melted butter
- Vanilla extract
Mix until the batter becomes smooth and glossy.
The consistency should resemble thick brownie batter.
Step 4: Add Optional Mix-Ins
Fold in your favorite add-ins such as:
- Chocolate chips
- Nuts
- Peanut butter swirl
These ingredients add texture and flavor complexity.
Step 5: Microwave the Brownie
Place the mug in the microwave and cook on high for 60–90 seconds.
Cooking times vary depending on microwave power.
The brownie is ready when:
- The top looks set
- The center remains slightly soft
Expert Tip: Slight undercooking keeps the brownie fudgy.
Step 6: Let It Cool Slightly
Allow the Microwave Brownie in a Mug to rest for 1–2 minutes.
This helps the brownie firm up and prevents burning your tongue.
Step 7: Add Toppings
Enhance your brownie with delicious toppings like:
