Nutella is my go-to treat. When I have more time I make Nutella Crumble Bars or Nutella Thumbprint Cookies, but on busy days a mug cake is the quickest path to chocolate happiness.
This Nutella Mug Cake is quick, fudgy and intensely chocolate-hazelnut — a single serving ready in minutes with pantry-friendly ingredients.
Why this Nutella Mug Cake is the best
- Ready in about 5 minutes. Mix, microwave and enjoy — really that fast.
- No flour required. This flourless mug cake is a convenient option when you’re out of flour or prefer gluten-free treats.
- Single serving. No fuss, no leftover slices. Make exactly one mug whenever you want dessert.
- Just a few ingredients. You likely already have everything needed to whip this up quickly.
- Serves beautifully with ice cream. A scoop of vanilla or a drizzle of extra Nutella finishes it perfectly.
Ingredients
- Nutella: Or any chocolate-hazelnut spread you prefer.
- 1 large egg: Room temperature is ideal.
- Unsweetened cocoa powder: Use dark cocoa for a deeper chocolate flavor if you like.
- Sugar or sweetener: 1–2 teaspoons, adjust to taste. Honey or maple syrup can be used instead.
- Vanilla extract: ½ teaspoon to round the flavors. A small pinch of sea salt enhances the chocolate.

How to make this flourless Nutella mug cake
- Whisk Nutella, egg, cocoa powder, sugar and vanilla together until smooth.
- Pour the batter into a microwave-safe mug (choose one with straight sides so it rises evenly).
- Microwave for about 60–75 seconds. Start with 60 seconds and add 10–15 seconds if needed; avoid overcooking.
- Let the cake cool for a few minutes, then serve straight from the mug with a scoop of ice cream or an extra drizzle of Nutella.

This really is one of the easiest cakes you can make.
Expert tips and notes
- Microwaves vary. Cook times differ by model and power — watch the cake and stop when it has risen and no longer looks wet on top.
- Choose the right mug. A straight-sided, microwave-safe mug helps the cake rise evenly.
- Begin with 60 seconds. If a toothpick comes out wet, microwave in short 10–15 second bursts until set.
- Adjust sweetness. Nutella is already sweet, so just a little extra sugar is often enough to balance the cocoa’s bitterness.

Optional add-ins
Customize the mug cake with any of these quick additions:
- Chocolate chips
- Espresso powder for a mocha kick
- Chopped toasted hazelnuts for crunch
- An extra dollop of Nutella in the center for a molten core
FAQs
If it’s rubbery, it was likely overcooked. Start with 60 seconds and add short increments until done to avoid drying it out.
Yes. Preheat the oven to 350°F, transfer batter to a small greased ramekin, and bake about 12–15 minutes until set. Baking will take longer but still yields a tasty single-serving cake.
