Ingredients for 1 Minute Microwave Brownie In A Mug

- 4 tablespoons (1 ¼ oz/35g) all-purpose flour
- 3-4 tablespoons (1 oz/28g) unsweetened cocoa powder (adjust to taste)
- 3 tablespoons dark brown sugar (or substitute with granulated sugar)
- Pinch of salt
- 6 tablespoons (3 fl oz/90ml) milk (dairy or non-dairy alternatives work)
- 2 tablespoons flavorless oil (canola, vegetable, or sunflower oil)
- ½ teaspoon vanilla extract
- 1 tablespoon semi-sweet chocolate chips (optional, but recommended!)
Step-by-Step Instructions
- In a medium microwavable mug (about 1 cup capacity), combine the flour, cocoa powder, brown sugar, and salt. Mix well to ensure no lumps.
- Add the milk, oil, and vanilla extract to the dry ingredients. Stir until you have a smooth, consistent batter.
- Fold in the chocolate chips evenly throughout the batter. (If you’re not ready to cook immediately, refrigerate the batter for up to 24 hours.)
- Microwave on high for 1 minute 40 seconds to 1 minute 50 seconds, or until the brownie has risen and the surface no longer looks wet. (Timing is based on a 1200W microwave; adjust as needed for your appliance.)
- Let cool slightly, then serve warm with a scoop of vanilla ice cream for the ultimate treat. Enjoy!
Perfect Pairings: Toppings & Serving Ideas
Take your microwave brownie to the next level with delicious toppings! A scoop of vanilla ice cream is a classic choice, but you can also try whipped cream, caramel drizzle, or a sprinkle of sea salt for a gourmet touch. For a fruity twist, add fresh berries or a dollop of raspberry jam. Don’t forget a dusting of powdered sugar for a simple yet elegant finish!
Quick Storage & Reheating Tips
If you don’t devour your brownie right away, store it in the mug covered with plastic wrap or transfer it to an airtight container. It will stay fresh at room temperature for up to 24 hours.
To reheat, microwave for 15-20 seconds until warm and gooey again. Pro tip: Add a few extra chocolate chips before reheating for an extra indulgent treat!
Fun Variations to Mix It Up
Customize your mug brownie to suit your cravings! Swap the chocolate chips for white chocolate, peanut butter chips, or chopped nuts.
For a richer flavor, use dark cocoa powder or add a teaspoon of espresso powder. Feeling adventurous? Stir in a tablespoon of Nutella or peanut butter for a decadent twist. The possibilities are endless!
Microwave Mastery: Timing & Equipment Tips
Microwaves vary, so keep an eye on your brownie as it cooks. Start with 1 minute 40 seconds and check for doneness—it should rise and look set, not wet. If needed, add 10-second increments until perfect. Use a microwave-safe mug that’s at least 1 cup in size to prevent overflow. A wide, shallow mug works best for even cooking.
Common Questions Answered
Can I use a different sweetener? Yes, you can substitute the brown sugar with granulated sugar or coconut sugar, but the texture may vary slightly. Can I make it gluten-free? Absolutely! Swap the all-purpose flour for a gluten-free blend.
What if I don’t have chocolate chips? No problem—just skip them or use chopped chocolate or even a drizzle of chocolate syrup instead.
