Why You’ll Love This 3 Ingredient Nutella Mug Cake
Done in 2 minutes flat. This 3 ingredient Nutella mug cake goes from mixing spoon to first bite in about 2 minutes, which makes it one of the fastest desserts you can possibly make at home.
Only 3 basic ingredients. Nutella, egg, and flour are all you need. No butter, no cocoa powder, no extra sugar, and no complicated measuring lineup taking over the counter.
No oven needed. Everything happens in one mug and one microwave. That means no preheating, no baking tray, and almost no cleanup after you are done.
Rich, fudgy, deeply chocolatey flavor. Nutella does all the heavy lifting here — hazelnut richness, cocoa depth, and sweetness all built in. The result tastes far more decadent than a 3-ingredient recipe has any right to.
Perfect single-serve dessert. This is not a huge cake tempting you for three extra slices. It is just enough for one very satisfying treat, which makes it ideal for portion-friendly dessert cravings.
Easy to customize. Add chocolate chips, a scoop of ice cream, chopped hazelnuts, or a pinch of sea salt. The base recipe is simple enough to welcome every small upgrade.
Ingredients
Gathering these simple ingredients sets you up for success with this 3 ingredient Nutella mug cake.
Nutella (4 tbsp) is the star of the entire recipe. Because it already contains cocoa, hazelnuts, sugar, and fat, it acts as the flavor base and richness booster all at once. According to Nutella’s own ingredient information, it is designed to be smooth, sweet, and spreadable — exactly what helps this cake stay soft and plush in the microwave.
Egg (1 large) binds everything together and gives the mug cake structure. It is what turns the Nutella from a soft spread into an actual cake batter. Let the egg come closer to room temperature if possible so it blends more smoothly.
All-purpose flour (2 tbsp) gives the cake enough body to rise and hold its shape. Too much flour makes the cake dry and rubbery, so keep the measurement level and accurate.
A microwave-safe mug is technically not edible, but it matters. Choose a standard 10- to 12-ounce mug with enough headroom so the batter can puff up slightly without overflowing.
Optional toppings like whipped cream, vanilla ice cream, chopped hazelnuts, mini chocolate chips, or a dusting of powdered sugar take the dessert from fast and satisfying to flat-out dangerous. They are not required, but they make the experience even better.

Instructions (Recipe Card)
- Add Nutella, egg, and flour directly to a microwave-safe mug.
- Stir thoroughly until completely smooth, making sure no flour pockets remain at the bottom.
- Microwave on high for 60 to 90 seconds, depending on your microwave’s strength.
- Stop when the top looks set but the center still appears soft and slightly fudgy.
- Let it rest for 1 minute before eating. Top as desired and serve warm.
Note: Microwave mug cakes keep cooking from residual heat after they come out. A slightly underdone center is usually perfect after a 1-minute rest. Overcooking is the fastest way to turn a fudgy mug cake into a rubbery one.
Instructions
Choose the right mug. Use a microwave-safe mug with enough headroom so the batter can rise slightly without spilling over. A mug that is too small creates a mess; a mug that is too wide can make the cake cook unevenly.
Mix the batter until absolutely smooth. Add the Nutella, egg, and flour directly to the mug and stir with a fork or small whisk until the mixture becomes glossy and fully combined. Scrape the bottom and corners well — hidden flour streaks are the reason many mug cakes turn patchy or dense.
Microwave in short, sensible bursts. Start with 60 seconds on high. Then check the center. If it still looks very wet, continue in 10-second bursts until the top is just set. Serious Eats and other microwave-dessert guides consistently point out the same thing: mug cakes go from perfect to overcooked very quickly.
Let the cake rest before digging in. This is one of the most important steps. The cake finishes setting from residual heat, and the crumb becomes much more tender after 1 minute of rest. Cutting into it too early can make it seem underdone when it is actually still settling.
Add toppings while it is warm. A spoonful of whipped cream, a scoop of vanilla ice cream, chopped toasted hazelnuts, or even a pinch of flaky sea salt makes the whole dessert feel much more special. The warm cake and cool topping contrast is what makes this dessert truly irresistible.
Serve immediately. Like most microwave mug cakes, this one is at its absolute best warm and fresh. That is when the center is softest, the Nutella aroma is strongest, and the texture feels most cake-like rather than brownie-firm.
Pro Tips for the Best Nutella Mug Cake
Do not overmix once smooth. Stir enough to remove lumps, then stop. Overworking a tiny batter can make the finished texture a little heavier.
Know your microwave. A powerful microwave may finish the cake in 60 seconds, while a weaker one may need closer to 90. The first time you make it, stay close and check early.
Underbake slightly for a fudgier center. If you love that molten, spoonable middle, pull the mug cake when the top looks set but the center still has a little softness.
Use level flour, not heaped flour. Too much flour is one of the main reasons mug cakes become dry. Measure carefully and keep the balance right.
Add a pinch of salt if your Nutella tastes very sweet. That tiny bit of contrast sharpens the chocolate-hazelnut flavor and makes the dessert taste more balanced.
Top smart, not heavy. A little whipped cream or ice cream is amazing. A giant pile of toppings can weigh the cake down and make the texture less appealing in such a small serving.
Serving Suggestions and Storage
Serve with vanilla ice cream. The cold, creamy contrast against the warm chocolate cake is classic for a reason.
Add chopped hazelnuts. They reinforce the Nutella flavor and bring crunch to an otherwise super-soft dessert.
Dust with powdered sugar. It makes the mug cake feel bakery-pretty with almost no effort.
Eat it fresh. Mug cakes are not really make-ahead desserts. This recipe is designed for immediate gratification, and that is exactly when it tastes best.
If you must save leftovers, cover and refrigerate up to 1 day. Reheat very briefly — 10 to 15 seconds at most — or the cake can turn tough.
Do not freeze. The texture is too delicate and small-batch to survive freezing well. This is one of those desserts best enjoyed in the moment.

Frequently Asked Questions
Can I make this 3 ingredient Nutella mug cake without egg?
This exact version depends on the egg for structure, so removing it changes the result significantly. For egg-free mug cakes, you usually need a different formula altogether using milk, baking powder, and a bit of oil. If you want a fast dessert with a similarly easy method, our Strawberry Cheesecake Overnight Oats – No Cook, 5 Minute Meal Prep gives you that same instant-gratification energy in cold dessert form.
Why did my mug cake turn rubbery?
Overcooking is almost always the reason. Microwaves vary a lot in strength, and even 10 extra seconds can make a big difference. Start lower, then add time only if needed.
Can I double the recipe?
You can, but it is usually better to make two separate mugs rather than one large one. Doubling in a single mug often leads to uneven cooking and overflow.
Can I add chocolate chips or nuts?
Absolutely. A tablespoon of chocolate chips, chopped hazelnuts, or even a small spoonful of peanut butter in the center works beautifully. Just keep additions modest so the cake still cooks evenly.
Is this more like cake or brownie?
It sits somewhere between the two, depending on cook time. Microwave it a little less and it feels fudgier, almost brownie-like. Cook it a touch longer and it becomes more soft-cake in texture.
