This brownie in a mug recipe makes one generous brownie. Adam and I often split one and enjoy it with a big scoop of ice cream. The egg gives the brownie more structure and lift, but leave it out if you prefer a fudgy, super moist brownie. Chocolate chips are optional but delicious.
2 tablespoons (28g) coconut oil or butter, melted
1/4 cup (32g) all-purpose flour
2 tablespoons (16g) unsweetened cocoa powder
1/4 cup (50g) brown sugar
1 ½ tablespoons coffee or milk
1/2 teaspoon vanilla extract
1 large egg
Pinch fine sea salt
1 tablespoon chocolate chips, optional
Whisk the melted coconut oil, brown sugar, coffee, egg, vanilla, and a small pinch of salt in a small bowl until blended.
Sift in the flour and cocoa powder and whisk until combined. Stir in chocolate chips (optional).
Carefully pour the batter into the mug. Clean any drips around the edges of the mug, then microwave for 1 minute and 30 seconds to 1 minute and 45 seconds.
Serve with a sprinkle of salt on top, if you like. Top with your favorite brownie toppings (ice cream is always a good choice).
