Vanilla Mug Cake in the Microwave
A single-serving vanilla cake cooks directly in a microwave-safe mug.
This single-serving vanilla mug cake mixes directly in a microwave-safe mug and cooks in about a minute. Measure the flour loosely, stir until no dry pockets remain and leave room for the batter to rise. Microwave power varies, so start with the shorter time and add brief bursts until the top looks set. Let it stand before eating because the mug will be hot. In a 350-ml (12-ounce) microwave-safe mug, stir flour, sugar, baking powder and salt. Add milk, oil and vanilla; stir until smooth, scraping the bottom and sides. Fold in chocolate chips if using; keep the mug no more than half full. Cook at 800 watts for 60 seconds; check the center and add 10-second bursts until just set.
