5-Minute Chocolate Mug Cake
This 5-Minute Chocolate Mug Cake is a rich, gooey dessert made with real dark chocolate, butter, and minimal flour. It's quick, simple, and delivers deep chocolate flavor with a soft, fudgy center—all without turning on the oven.
Ingredients
Main
- 42 g dark chocolate chopped, or 1/4 cup chocolate chips
- 3 tbsp unsalted butter
- 3 tbsp granulated sugar
- 1 large egg
- 2 tbsp all-purpose flour
Instructions
- Step 1: Place the chocolate and butter in a small heat-safe bowl. Microwave for 30 seconds, then stir. Continue heating in 20-second bursts, stirring each time, until smooth.
- Step 2: Mix in the sugar while the chocolate is still warm. The batter should look shiny and thick.
- Step 3: Add the egg and whisk quickly until the mixture is smooth and slightly thickened.
- Step 4: Stir in the flour just until smooth. Stop mixing once there are no dry spots.
- Step 5: Pour the batter into a 12 oz mug to allow room for rising.
- Step 6: Microwave for 1 minute at 700–750 watts. If the top looks wet, add 5–10 seconds. Let rest for 2 minutes before eating.
Notes
For extra flavor, consider adding 1 tsp peanut butter to the center before cooking, a pinch of espresso powder to boost the chocolate flavor, or a sprinkle of sea salt on top after cooking. Top with ice cream or whipped cream for an indulgent finish. This cake is best enjoyed fresh and warm.
