Popularized by social media for its speed and simplicity, the chocolate mug cake is perfect for those late-night cravings or for sharing a quick sweet moment with someone special.

  • Minimal Ingredients: Only pantry staples required—no eggs, no fuss.
  • Rich and Decadent: Packs a genuine chocolate punch, especially with chocolate chips mixed in.
  • Single Serving: Sunset your cravings without leftovers tempting you.
  • Flexible: Make it your own by adding extras or swapping out ingredients.

Essential Ingredients

Gather these classic baking staples for a quick, satisfying mug cake experience:

IngredientAmount
All-purpose flour3 tablespoons
Sugar3 tablespoons
Cocoa powder (unsweetened)2 tablespoons
Baking powder1/4 teaspoon
SaltPinch
Whole milk3 tablespoons
Vegetable oil3 tablespoons
Vanilla extractSplash (about 1/4 teaspoon)
Semi-sweet chocolate chips (optional but highly recommended)3 tablespoons

Note: For a vegan version, simply swap the milk for a plant-based alternative and use dairy-free chocolate chips.

Step-by-Step Directions

  1. Add Dry Ingredients: In a 12-ounce microwave-safe mug, add the flour, sugar, cocoa powder, baking powder, and a pinch of salt. Mix thoroughly with a fork to ensure even distribution and no clumps.
  2. Add Wet Ingredients: Pour in milk, vegetable oil, and a splash of vanilla extract. Stir using the fork, scraping the bottom and sides, until the mixture is smooth and glossy.
  3. Fold in Chocolate Chips: Sprinkle in the chocolate chips and gently fold until they’re evenly distributed throughout the batter.
  4. Clean the Mug Rim: Using a damp paper towel, wipe any streaks of batter from the inside upper rim of the mug to prevent burning and to keep cleanup easy.
  5. Microwave: Place the mug in the microwave and cook on high for 90 seconds. The cake should puff up and set on top but remain tender and moist inside.
  6. Let It Stand: Allow the mug cake to sit undisturbed for 1½ to 2 minutes after microwaving. This resting period finishes the cooking process and slightly cools the dessert, preventing burns.
  7. Serve: Top with a dollop of sweetened whipped cream or a scoop of vanilla ice cream. For extra flair, sprinkle with colored sugar or chocolate shavings.

Visual Walkthrough

  • Add and mix dry ingredients directly in your mug for fewer dishes.
  • Stir in milk, oil, and vanilla; the batter will thicken as you mix.
  • Gently fold in the chocolate chips for gooey pockets of chocolate.
  • The batter will rise—be sure to use a mug that holds at least 12 ounces.
  • In just 90 seconds, your cake will be soft, tender, and deeply chocolaty.

Expert Tips for Success

  • Don’t Overcook: Over-microwaving leads to dry, rubbery cake. Stop at 90 seconds and let stand for a couple of minutes as it will continue to set.
  • Choose the Right Mug: Use a mug that holds at least 12 ounces. This allows space for the batter to rise while cooking.
  • Mix Well: Make sure there are no flour or cocoa streaks left at the bottom before microwaving—undermixed batter can result in soggy spots.
  • Sweetness Factor: The base recipe is sweet and chocolatey, but you can adjust the sugar to your personal taste.
  • Split for Two: This recipe is rich—consider sharing with a friend or partner for the perfect two-spoon treat.

Creative Variations & Add-Ins

  • Espresso Shot: Add 1/2 teaspoon instant espresso powder for a mocha flavor.
  • Nutty Crunch: Mix in chopped walnuts, pecans, or almonds.
  • Peanut Butter Swirl: Swirl in a teaspoon of peanut butter after mixing the batter for a gooey surprise.
  • Spice It Up: Add a pinch of cinnamon, cayenne, or chili powder for warmth and complexity.
  • Berry Burst: Fold in a few fresh or frozen raspberries or cherries before microwaving.

Perfect Toppings for Your Mug Cake

After microwaving your cake, the real fun begins—the toppings! Try these for added decadence and flair:

  • Whipped Cream: A classic dollop adds lightness and creaminess.
  • Vanilla or Chocolate Ice Cream: The heat of the cake melts the ice cream for a luscious flavor contrast.
  • Sprinkles or Chocolate Shavings: Sprinkle a handful for visual appeal and texture.
  • Crushed Cookies: Sprinkle Oreos or graham crackers on top for crunch.
  • Fresh Fruit: Add sliced strawberries, berries, or bananas for color and tartness.

Why This Recipe Works

  • Microwave Magic: Rapid heating causes the baking powder to react quickly, rising the cake in moments and creating a tender crumb.
  • No Eggs Needed: The combination of milk and oil ensures moisture without the need for an egg.
  • Chocolate Chips: These melt into gooey pockets, amping up the decadence with every bite.

Frequently Asked Questions (FAQs)

Q: Can I make this recipe vegan or dairy-free?

A: Yes! Substitute non-dairy milk (such as almond, soy, or oat milk) for whole milk and use dairy-free chocolate chips. The cake will remain moist and delicious.

Q: Can I double the recipe?

A: It’s best to make mug cakes one at a time for even cooking. To make more servings, prepare each mug separately and microwave individually.

Q: How do I know when the mug cake is done?

A: The top of the cake should look set and slightly springy. If the center still appears very wet, microwave in 10-second increments, but avoid overcooking.

A: This recipe is designed for the microwave. For oven baking, transfer the batter to an oven-safe ramekin and bake at 350°F (175°C) for about 15 minutes, or until set.
