A rich, fudgy chocolate cake made in a mug and baked in the oven for a perfectly even crumb, topped with a glossy chocolate glaze. This single-serving treat is ready in under 20 minutes and satisfies any chocolate craving with a deep cocoa flavor and a moist, tender texture.
Store leftover mug cakes (without glaze) wrapped in plastic wrap in the refrigerator for up to 3 days. To reheat, microwave on high for 15–20 seconds until warm. For longer storage, freeze the baked cakes in an airtight container for up to 2 months; thaw overnight in the fridge and reheat as above. The glaze is best applied fresh, so if freezing, prepare the glaze separately.
