- 1 tablespoon coconut oil (melted)
- 2 tablespoons unsweetened coconut milk or low-fat milk

How to Make a Microwave Mug Brownie
Making this mug brownie is as easy as mixing, microwaving, and enjoying—all in the same mug!
- Melt the Coconut Oil: Add the coconut oil to a small, microwave-safe coffee mug and microwave on high for 15–20 seconds until melted. Let cool for 1 minute to avoid cooking any other ingredients too quickly.
- Mix the Wet Ingredients: Whisk in the coconut milk (or low-fat milk) and vanilla extract until well combined.
- Add the Dry Ingredients: Stir in the flour, sugar, cocoa powder, and salt. Whisk until the mixture is smooth and free of lumps.
- Optional Add-Ins: Fold in the mini chocolate chips if you’d like an extra chocolatey surprise.
- Microwave: Place the mug back in the microwave and cook on high for 30–40 seconds. The brownie should look firm to the touch and no longer glossy. Be cautious not to overcook, as it continues to set while cooling.
- Let It Cool: Allow the mug brownie to stand for 8–10 minutes before digging in—this ensures the perfect texture!
Test Kitchen Tips for the Perfect Microwave Mug Brownie
- Don’t Skip the Cooling Time: It might be tempting to dive right in, but resting the brownie gives it time to firm up and develop its ideal texture.
- Mug Size Matters: Use a standard-sized coffee mug to prevent overflow while cooking.
- Customize Your Flavor: Swap vanilla extract for peppermint or almond extract for a fun twist.
- Make It Vegan: Use plant-based milk like almond or soy milk and dairy-free chocolate chips.
