Add the egg, melted butter, and vanilla extract to the mug. Mix everything thoroughly until the batter is smooth with no lumps.
Microwave on high for 60 to 90 seconds. Keep an eye on the cake as microwave powers vary—stop cooking when the cake has risen and is set but still moist inside.
Let the mug cake cool for a minute or two before digging in. It can be enjoyed plain or topped with a dollop of whipped cream or fresh berries if desired.

Ingredient Swap Ideas

Adjusting ingredients helps fit this mug cake to different preferences or dietary needs while keeping its core appeal. Here are some manageable swaps to try:

Chocolate – Use cocoa powder and small chocolate chips instead of ready-made chocolate for a richer flavor.
Marshmallows – Choose vegan marshmallows or mini coconut marshmallows for a plant-based twist.
Sugar – Swap granulated sugar with maple syrup or honey for a natural sweetener option, adjusting liquid slightly.
Flour – Substitute all-purpose flour with almond flour to add a nutty note and make it gluten-free.
Milk – Use any plant-based milk like oat or almond milk without impacting overall texture much.

Ingredients

4 tablespoons all-purpose flour – The foundation of the cake’s structure.
4 tablespoons granulated sugar – Adds sweetness to balance the cocoa.
2 tablespoons unsweetened cocoa powder – Provides a deep chocolate flavor throughout.
1/8 teaspoon baking powder – Helps the cake rise lightly in the microwave.
3 tablespoons milk – Moistens the batter for a tender crumb.
2 tablespoons vegetable oil – Enhances moisture and richness.
1/4 teaspoon vanilla extract – Adds subtle warmth and enhances chocolate notes.
2 tablespoons mini marshmallows – Melts to form a melty topping.

Instructions

In a microwave-safe mug, combine the flour, sugar, cocoa powder, and baking powder. Stir well to distribute the dry ingredients evenly.
Add the milk, vegetable oil, and vanilla extract to the mug. Mix thoroughly until a smooth batter forms, making sure no lumps remain.
Sprinkle the mini marshmallows evenly over the surface of the batter. They will melt and create the gooey topping as it cooks.
Microwave the mug on high for 1 to 1½ minutes. Cooking time may vary based on your microwave, so watch for the cake to rise and set while the marshmallows melt.
Let the mug cake cool slightly before eating, as it will be very hot. Enjoy directly from the mug for a cozy, fuss-free dessert.
