What You Need to Make This Chocolate Mug Cake
Ingredients are basic and likely on hand: all-purpose flour, granulated sugar, unsweetened cocoa powder, baking soda, a pinch of salt, white or apple cider vinegar, vanilla extract, a neutral oil (vegetable or canola), and water. No eggs, milk, or butter required.
How to Make a Chocolate Mug Cake
You can mix the batter directly in the mug or in a small bowl and transfer it to the mug. Use a large microwave-safe mug (around 16 ounces) and lightly coat the inside with non-stick spray or a little oil. Combine the dry ingredients in the mug: flour, sugar, cocoa, baking soda, and salt. Stir them together so they are evenly distributed.
After mixing the dry ingredients, make three small wells in the mixture. Pour the vinegar in one well, the vanilla in another, and the oil in the third. Pour the water over everything and mix thoroughly with a fork until you have a smooth batter.
Optional add-ins: press a tablespoon of hazelnut chocolate spread, peanut butter, caramel pieces, or a Rolo into the center of the batter before microwaving for a gooey surprise. Mini chocolate chips work well folded into the batter or sprinkled on top after baking.
Microwave on high for approximately 2 minutes uncovered. Microwaves vary, so start checking at 1 minute 20 seconds to 1 minute 40 seconds if yours runs hot. Use a toothpick to test doneness—when it comes out clean or with just a few moist crumbs, the cake is done. Avoid overcooking to keep the texture moist.
Top the cake with powdered sugar, frosting, whipped cream, chocolate sauce, or caramel. Serve warm or allow it to cool and enjoy at room temperature. Allow a minute or two to cool slightly before digging in to avoid burning your mouth.
My family has relied on this mug cake for years—it’s a dependable, quick dessert during busy weeks or quiet evenings. It’s an excellent recipe to keep handy for last-minute sweet cravings.
