There's something very satisfying about microwave mug cakes. They're the perfect single-serving dessert, and this one really couldn't be easier!

It comes together with a handful of ingredients in minutes. All you need is Nutella, a popular chocolate hazelnut spread, an egg, flour of choice, and a few minutes. The result is a gooey, moist, fudgy, and absolutely irresistible chocolate cake!

Ingredients- Notes & Substitutions

These three ingredients couldn't be simpler. No baking powder needed! Here's what you need to make Nutella cake in a mug:

Ingredients for Nutella Mug Cake on a counter

Nutella: This chocolate hazelnut spread is sweet, creamy, and absolutely decadent. You can use your favorite brand.
Egg: This is what keeps this cake moist and fudgy. (Scroll to the 'Variations' section for eggless cake.)
Flour: For a regular cake, use all-purpose flour or almond flour for a gluten-free mug cake.

Scroll to the recipe card for a detailed list of ingredients and quantities.

How to Make Nutella Mug Cake

Add the Nutella, flour, and egg to a 12-oz. microwave-safe coffee mug. Whisk together until the cake batter is smooth and lump-free.

Nutella Scooping Tip: Since Nutella is thick and sticky, spray your spoon or spatula with cooking spray or rub a little oil for easy release.

Adding ingredients to a mug to make Nutella Almond Flour Mug Cake

Microwave for 50-55 seconds, depending on your microwave strength. The cake is ready if it detaches on the sides. If it looks uncooked, pop it in for another 10 seconds.

Let the cake cool for 2 minutes before serving. Enjoy it as it is, or top it with whipped cream or vanilla ice cream.

Serving Suggestions

This mug cake is absolutely decadent on its own, but you can fancy it up a bit with toppings. Some of my favorites are:

A scoop of ice cream
Whipped cream
Strawberries or other fresh fruit
Caramel sauce
Frosting of choice

Try a Variation

Eggless Nutella Mug Cake: To make a Nutella mug cake without eggs, follow the instructions as written, but sub out the egg with ¼ cup of 2% milk and ¼ teaspoon of baking powder. You'll still get a rich, gooey mug cake without the egg!
Chocolate Chips: For more gooey-chocolate pockets, stir in 2 teaspoons of bitter-sweet or semi-sweet chocolate chips.
Add Nuts: Add 2 teaspoons of chopped walnuts to the batter for a nutty twist.
Add Baileys: Add a tablespoon of baileys to the batter for an Irish Coffee-inspired flavor.
Peanut butter: Add 2 teaspoons of peanut butter and swirl it in the batter using a fork.

Using Almond Flour vs. All-Purpose Flour

Whenever I get a chance, I like to swap out all-purpose flour with almond flour. That makes these rich and fudgy mug cakes gluten-free and cuts down the carb content by about 19 grams.

Two tablespoons (1oz.) of all-purpose flour contain about 22 grams of total carbs with under 1 gram of fiber, or about 21 grams of net carbs. The same quantity of almond flour contains 5.6 grams of total carbs with 3 grams of fiber or about 2.4 grams of net carbs.

While this cake is not low-carb, 19 grams is a huge saving for when I want to indulge but still keep a check.

Recipe Tips & Notes

Nutella Scooping Tip: Since Nutella is thick and sticky, spray your spoon or spatula with cooking spray or rub a little oil for easy release.
Cooking time: Depending on your microwave strength, the cooking time may vary between 50 seconds and 1 minute.
Check for doneness: The cake is done when it detaches on the sides. If the center looks undercooked, check at the 50-55 second mark and put it in for another 10-15 seconds.
Serve right away: This mug cake is best enjoyed right away. You can assemble it a few hours ahead of time, but microwave it just before serving.
Make it egg-free: You can easily make this cake eggless by skipping the egg and adding ¼ cup of 2% milk + ¼ teaspoon of baking powder.
Split it: Since this is a heavy cake, you can split the batter between two 6oz. mugs. and adjust the microwave time to 30 seconds.
Customize accompaniments: This fudgy cake is great on its own, but feel free to enjoy it with whipped cream, ice cream, or berries.

Common Questions

Why did my mug cake explode?

Overfilling your mug can cause your mug cake to explode, so you should use large cups for baking in a microwave. For this recipe, use a cup that is at least 12 ounces or larger.

Do Mug Cakes work?

Yes! While they're not the same as traditional cakes, mug cakes make a tasty single-serving treat.
