    I love lava cakes, but sometimes I just want a super-quick chocolate fix. This espresso chocolate cake in a mug recipe is a weeknight-worthy substitute that I make right in the microwave. I make cake in a mug at least once a month, especially if my husband and kids aren’t around for dinner and I’m craving something warm and sweet after dinner. This cake in a mug is over-the-top gooey and cleanup is as quick as throwing the mug in the dishwasher.

    Quick Microwave Espresso Chocolate Cake in a Mug Recipe

    I make this weeknight-worthy dessert right in the microwave.

    Servings: 2


    • semi-sweet chocolate chips: 1 ounce
    • unsalted butter: 4 tablespoons
    • eggs, large: 2
    • vanilla extract: 1 teaspoon
    • sugar: ¼ cup
    • instant espresso powder: 1 teaspoon
    • salt: ¼ teaspoon
    • flour: ¼ cup
    • baking powder: ½ teaspoon


    Step 1: Melt the chocolate and butter in a small microwavable bowl until melted. Remove from the microwave and whisk until chocolate is melted. Allow to cool slightly before whisking in eggs, sugar, and vanilla.

    Step 3: Divide batter among two microwavable mugs. Place in microwave. Cook time will vary depending on microwave, but generally this cake in a mug cook in 30 seconds on HIGH. Mug cakes will still look wet, but resist the urge to cook longer if you want to have a molten texture to your cakes.
