Brownie in a Mug
Step-by-Step Instructions
- Mix the Dry Ingredients: In a microwave-safe mug, whisk together the flour, cocoa powder, sugar, and salt until well combined. No lumps allowed!
- Add the Wet Ingredients: Pour in the oil, milk, and vanilla extract. Stir everything with a fork until smooth – about 30 seconds. If you’re adding chocolate chips, fold them in now.
- Microwave Magic: Pop the mug in the microwave and cook on high for 1 minute. Check the center; if it’s still too gooey, zap for another 10-20 seconds. Remember, it continues cooking a bit after you take it out.
- Let It Cool (A Little): Wait 1-2 minutes to avoid burning your tongue, then dig in straight from the mug.

Pro Tips for the Perfect Mug Brownie
- Mug Size Matters: Use a standard 8-12 oz mug to prevent overflow.
- Power Levels Vary: Microwaves differ, so start with less time and adjust.
- Texture Tweaks: For a cakier brownie, add a tiny pinch of baking powder.
- Top It Off: Vanilla ice cream, whipped cream, or a drizzle of peanut butter takes it to the next level.
Fun Variations to Try
- Nutty Delight: Stir in chopped walnuts or pecans.
- Minty Fresh: Add a drop of peppermint extract and top with crushed candy canes.
- Vegan Twist: Use plant-based milk and oil; skip the butter.
- Double Chocolate: Mix in white chocolate chips for contrast.
