Ingredients

It’s easy to make a chocolate mug cake.

Step 1: Combine the Dry Ingredients
In a microwave-safe mug, mix the flour, sugar, cocoa powder, baking powder and salt until evenly combined.

Step 2: Add the Wet Ingredients
Add the milk, vanilla essence and vegetable oil. Stir until the batter is smooth and no lumps remain. Fold in the chocolate chunks.
Step 3: Put the Cake in the microwave.
Microwave on high for approximately 60 seconds in a 900–1000 watt microwave. If the centre still looks very wet, continue in 10-second intervals. Avoid overcooking because the cake will continue setting briefly after removal.

Step 4: Serve the Chocolate Mug Cake
Allow the cake to cool for one minute before eating, as the mug and melted chocolate may be hot. Add chocolate syrup, ice cream or fresh berries, if desired, and serve it warm.
