Step 1
Mix flour, cocoa, sugar, and espresso powder in a microwave-safe mug or small bowl.
Step 2
Stir in milk and 1 tbsp butter until just combined—batter should be thick and lumpy.
Step 3
Microwave on high for 90 seconds. Cake will rise and look barely set on top—that's right.
Step 4
While cake cools 30 seconds, heat remaining 1 tbsp butter and chopped chocolate together in a small bowl (microwave 20 seconds, stir until glossy).
Step 5
Pour warm fudge frosting over the warm cake. Let it settle and pool into the warm crumbs.
Step 6
Serve warm in the mug or turn out onto a plate. Eat with a spoon while fudge is still gooey.
