3-Ingredient Mug Cake (No Egg)

A mug cake is for the night when something sweet is needed and nothing is going to be baked. Three ingredients, one mug, about ninety seconds in the microwave. There is no pan to wash and no leftover half a cake to finish out of obligation.

The mug does more than hold it. Batter rises hard and fast under a microwave and needs roughly twice its own volume of room, so a standard twelve ounce mug filled less than halfway is about right. A narrow mug sends the middle straight over the rim.

Microwaves vary enough that the first one is a test. Start at sixty seconds, then go in ten second steps, and stop while the top still looks barely damp. A mug cake turns from soft to rubbery in the last few seconds, because the sugar keeps cooking after the microwave stops.

3-Ingredient Mug Cake (No Egg)

Cake in a mug in about two minutes, with three ingredients you almost certainly already have. No egg, which makes it quicker to throw together and suitable for anyone avoiding eggs. The texture is soft and fluffy enough to feel genuinely cake-like.

Ingredients

  

• 4 tablespoons self-raising flour see notes for a plain flour substitution
• 3 tablespoons granulated sugar
• 3 tablespoons milk full-fat works best

Instructions

 

• Add the self-raising flour and granulated sugar to a large microwave-safe mug and stir together briefly with a fork.
• Pour in the milk and mix until the batter is completely smooth, with no dry streaks of flour at the bottom of the mug.
• Microwave on high for 60 to 90 seconds, checking at 60 seconds. The cake is ready when the top looks just set and is no longer visibly wet – it keeps cooking from residual heat, so pull it early rather than late.
• Let it sit for 30 seconds before eating. Eat from the mug, or tip it onto a small plate.

Notes

Equipment: one large microwave-safe mug (at least 12 oz / 350 ml) and a fork.

Microwave wattage: timing is calibrated for a standard 800-1000 W microwave. If yours runs lower, add 15-20 seconds. Your first batch is a calibration run.

Plain flour substitution: add 1/4 teaspoon baking powder per 4 tablespoons of plain flour.

Variations

• Chocolate: replace 1 tablespoon of the flour with 1 tablespoon unsweetened cocoa powder. Optionally stir in a teaspoon of peanut butter, or drop chocolate chips on top.
• Cinnamon brown sugar: swap the granulated sugar for brown sugar and add 1/2 teaspoon ground cinnamon to the dry ingredients. Pairs well with oat milk; finish with a pinch of flaky salt.
• Lemon: replace the milk entirely with 3 tablespoons fresh lemon juice (about half a lemon). Zest half the lemon into the batter for more citrus flavor.

Storage: best eaten immediately. Covered, it keeps at room temperature up to 12 hours or refrigerated up to 24 hours; reheat at 50% power for 15-20 seconds. The dry ingredients can be mixed in the mug ahead of time and the milk added when you are ready.
