3 Ingredient Nutella Mug Cake
Ingredients
- 1/4 cup (70 g) Nutella or any chocolate-hazelnut spread
- 1 large egg, at room temperature if possible
- 3 tablespoons all-purpose flour, leveled
- Pinch of salt to balance sweetness
- 1/4 teaspoon vanilla extract for extra aroma
- Chocolate chips or chopped hazelnuts for texture
Instructions
- Choose the right mug. Use a microwave-safe mug that holds at least 12 ounces. A wider mug cooks more evenly than a tall, narrow one.
- Whisk the egg first. Crack the egg into the mug and whisk with a fork until well blended. This prevents streaks of egg white in the finished cake.
- Add Nutella. Spoon in the Nutella and mix until the batter is smooth and uniform. If the Nutella is stiff, microwave it in the jar for 10 seconds first to loosen it.
- Stir in flour. Add the flour and a pinch of salt if using. Mix just until you no longer see dry streaks. Don’t overmix—gentle is best.
- Customize (optional). Fold in a few chocolate chips or nuts for extra richness and crunch.
- Microwave in short bursts. Cook on high for 45–60 seconds, then check. The top should look set around the edges with a slightly soft center. If needed, continue in 10–15 second bursts until done. Most microwaves finish this cake between 60–90 seconds.
- Rest briefly. Let the mug cake sit for 1–2 minutes. It continues to set and becomes easier to eat without burning your tongue.
- Top and enjoy. Add a scoop of ice cream, a drizzle of cream, or fresh berries. Eat warm with a spoon.
Why This Recipe Works
This mug cake keeps things simple on purpose. Nutella brings fat, sugar, and cocoa, which does most of the heavy lifting for both flavor and structure.
An egg provides lift and tenderness, while flour sets the crumb so it’s cake-like, not molten batter. Because the ingredients are few and balanced, the batter cooks quickly and evenly in the microwave. The result is a warm, soft cake with a gooey center, ready in under five minutes.
You’ll also love that it’s flexible—easy to tweak, and hard to mess up if you follow a few simple tips.

Storage Instructions
This mug cake is best fresh. The joy is in the warm, just-baked texture.
If you must store it:
- Short-term: Cover and refrigerate for up to 1 day. Reheat in the microwave in 10–15 second bursts until just warm. It will be denser after chilling.
- Make-ahead batter: Whisk the egg and Nutella together in a small jar, then add flour right before cooking.This keeps the cake from turning rubbery or dense.
- Freezing is not recommended, as thawing changes the texture and can make it dry.
Health Benefits
This isn’t a “health” dessert, but it does have a few redeeming qualities:
- Portion control: It’s a single-serve treat, which helps curb overindulging compared to a full cake.
- Protein from the egg: The egg adds a bit of protein, which can make the dessert more satisfying.
- Customizable sweetness: You control add-ins and toppings, so you can keep it simple or lighten it up.
That said, this is a sweet, high-calorie dessert. Enjoy it mindfully and balance it with the rest of your day.
What Not to Do
- Don’t overcook it. This is the number one mistake. An extra 15–30 seconds can turn your cake dry and rubbery.
- Don’t use a tiny mug. The batter can overflow, and a cramped mug cooks unevenly.
- Don’t pack the flour. Scoop lightly and level with a knife.Packed flour makes the cake dense.
- Don’t skip mixing the egg well. Unblended egg creates rubbery bits after microwaving.
- Don’t expect oven-baked texture. Mug cakes are softer and slightly fudgier by nature. That’s part of the charm.
Variations You Can Try
- Extra chocolatey: Stir in 1 tablespoon cocoa powder and add a splash more Nutella or a teaspoon of milk to keep it moist.
- Peanut butter swirl: Dollop 1 teaspoon peanut butter on top and swirl it in before microwaving.
- Mocha twist: Add 1/2 teaspoon instant espresso powder to the batter to deepen the chocolate flavor.
- Gluten-free swap: Use a 1:1 gluten-free flour blend. Avoid almond flour here—it changes the structure too much.
- Salted crunch: Sprinkle flaky sea salt and chopped hazelnuts on top after cooking.
- Birthday vibe: Fold in a teaspoon of rainbow sprinkles and top with whipped cream.
- Lava style: Under-cook by 5–10 seconds and press a square of chocolate into the center right after microwaving.
FAQ
Can I make this without eggs?
Yes.
Replace the egg with 3 tablespoons milk plus 1 tablespoon oil, and add an extra teaspoon of flour. The texture will be softer and more brownie-like, but still tasty.
How long should I microwave it?
Start with 45–60 seconds, then add in 10–15 second bursts until the top is set but the center is slightly soft. Every microwave is different, so watch closely the first time you make it.
Can I bake this in the oven instead?
You can, but it’s slower.
Bake in an oven-safe ramekin at 350°F (175°C) for about 12–15 minutes, or until the edges are set and the center is just barely jiggly.
What if I don’t have Nutella?
Use any chocolate-hazelnut spread. Chocolate peanut butter or chocolate almond butter can work too, but you may need a teaspoon of sugar if the spread is less sweet.
Why did my mug cake turn rubbery?
It was likely overcooked or overmixed. Microwave in short bursts and stop when it’s just set.
Mix only until the flour disappears, and whisk the egg thoroughly first.
Can I double the recipe?
It’s better to make two separate mugs. A large, double batch cooks unevenly and can overflow.
Is it safe to microwave a mug with metal accents?
No. Only use fully microwave-safe mugs without metallic paint, rims, or decorations.
How do I make it less sweet?
Add a pinch more salt, skip sweet toppings, and stir in a teaspoon of cocoa powder to balance the sweetness.
Can I add fruit?
Yes.
Gently press a few raspberries or sliced strawberries into the batter before microwaving. They’ll add moisture, so avoid overcooking.
Why is my cake dry?
It’s usually from overcooking or too much flour. Measure flour lightly and stop microwaving as soon as the top looks set.
In Conclusion
This 3 ingredient Nutella mug cake is the definition of easy comfort.
With a handful of pantry staples and a minute in the microwave, you get a warm, fudgy dessert that feels special without any fuss.
