Ingredients Needed
See the recipe card below for exact quantities and a printable version.
- All-purpose flour (maida): the base of the batter.
- Unsweetened cocoa powder: use good-quality cocoa for best chocolate flavor.
- Baking powder: helps the mug cake rise and become light.
- Powdered sugar: or powdered granulated sugar for a smooth batter.
- Vegetable oil: use a neutral oil to keep the cake moist.
- Milk: room-temperature milk; full-fat gives richer results.
- Dark chocolate or chocolate chips: a small piece placed in the center creates the molten core.
- Vanilla essence and optional instant coffee powder: enhance depth of flavor.
Substitutes and Variations
- Vegan option: replace regular milk with almond, soy, or coconut milk.
- Filling alternatives: swap the chocolate center for peanut butter, Nutella, or caramel for a different molten filling.
How to Make a Microwave Chocolate Mug Cake (Step-by-Step)
Step 1: In a microwave-safe mug, whisk together the dry ingredients.
Step 2: Add milk, oil, and vanilla and whisk until the batter is smooth.
Step 3: Press a small piece of chocolate into the center of the batter—do not stir.
Step 4: Microwave on high (700W) for about 80 seconds, adjusting time for your microwave. Alternatively, bake in a preheated convection oven at 180°C for 15 minutes. Let cool slightly before serving.
Allow the mug cake to rest for a minute to set, then dig in and enjoy the warm, gooey center.
Tips to Make the Best Microwave Mug Cake
- Use a microwave-safe mug that holds at least 1.5 cups to prevent overflow—mug cakes rise while cooking.
- Stir the batter until smooth to avoid dry pockets of flour; mix gently to prevent a tough texture.
- Place a microwave-safe plate under the mug to catch any spills and keep the microwave clean.
- Watch the cake closely after 1 minute of cooking; overcooking will dry it out and make it firm.
Recipe FAQs
Let it cool slightly, then serve. Popular options: a scoop of vanilla ice cream, whipped cream, marshmallows, fresh berries for brightness, or a light dusting of powdered sugar.
No preheating is required; the mug cake cooks directly in the microwave in about 80 seconds (depending on wattage).
Overcooking is the usual cause. Reduce the cooking time slightly and check the cake early to preserve a moist, soft texture.
Make sure you used the correct amount and a fresh baking powder. Too little baking powder prevents rise; too much can cause the cake to inflate then collapse.
