Step 1
Mix flour, cocoa powder, sugar, and baking powder in a small bowl until no lumps remain.
Step 2
Stir in oil and milk until you have a smooth batter — no dry streaks.
Step 3
Divide batter between two microwave-safe mugs, filling each halfway.
Step 4
Microwave each mug for 60–90 seconds on high. The surface should look set but the center jiggles slightly when you move the mug.
Step 5
Let cool 1 minute, then top with a sprinkle of sugar or cocoa powder if desired.
Step 6
Serve warm with a spoon. The center will be gooey and the edges cakey.
