Why You’ll Love This Recipe
This quick and easy chocolate mug cake produces a tender, melt-in-your-mouth crumb and is ideal for date nights, celebrations, or anytime you want a single-serve chocolate dessert without the fuss of baking a full-size cake. The recipe is eggless and uses simple pantry ingredients. It can be cooked in an 8 oz. mug or a small ramekin in the microwave in about two minutes—no oven required.
The topping is effortless: sprinkle chopped chocolate or chocolate chips over the hot cake and loosely cover for a few minutes so the chocolate melts. Then spread it with a spoon and add sprinkles if you like.
Ingredients:
- all-purpose flour
- granulated sugar
- unsweetened cocoa powder
- baking soda
- salt
- apple cider vinegar
- vanilla extract
- oil (vegetable or canola)
- water
- chocolate chips or chunks

Instructions:
Making this mug cake is straightforward. Whisk the ingredients into a smooth batter, pour into a greased mug or ramekin, and microwave until set.
- Grease an 8 oz. microwave-safe mug or ramekin and set aside.
- In a one-cup measuring cup or small bowl, whisk together the dry ingredients: flour, sugar, cocoa powder, baking soda, and salt.
- Add the apple cider vinegar, vanilla, oil, and water. Whisk until the batter is smooth and there is no dry flour at the bottom—use a spatula if needed.
- Pour the batter into the prepared mug. Sprinkle about 1 tablespoon of chocolate chips or chunks on top, or press a caramel-filled chocolate into the center for a gooey surprise.
- Microwave on high for 1 minute. Check the center—if it still looks wet, microwave for 15 seconds more and check again. Add 10-second bursts if needed until a toothpick inserted in a few spots comes out mostly clean.
- While the cake is still hot, sprinkle the remaining chocolate chips on top and loosely cover with an inverted small plate or a lid. Let sit a few minutes until the chocolate melts, then spread it with the back of a spoon or a small spatula. Add sprinkles if desired, let cool slightly, and serve.

No eggs or milk
This recipe is egg-free and dairy-free: the wet ingredients are apple cider vinegar, water, and oil, while the dry ingredients are flour, sugar, cocoa, baking soda, and salt. The result is a richly colored, soft, fluffy cake with a tender crumb—very similar to classic eggless chocolate cakes and cupcakes.
