A decadent, single-serve chocolate cupcake baked in a mug with a molten hot fudge center that oozes out when you cut into it. This quick and easy dessert is perfect for a spontaneous chocolate craving and requires no special equipment.
Storage: This is best eaten immediately. Leftovers can be stored covered in the refrigerator for up to 1 day, but the fudge center will solidify. Reheat gently in the microwave for 15-20 seconds. Make-Ahead: The dry ingredients can be pre-mixed in a small container for a quicker assembly. Variations: Add 1 tbsp of chocolate chips to the batter for extra chocolatey texture. For a gluten-free version, use a 1:1 gluten-free flour blend. Serve with a dollop of whipped cream or a scoop of vanilla ice cream for an extra treat.
