Why You’ll Love This Recipe
- Ready in 3 minutes flat — from craving to first bite, including microwave time
- Zero cleanup stress — mix and bake in the same mug, then eat straight from it
- Perfectly portioned — one generous serving means no temptation to overindulge or waste leftovers
- Nutella in every bite — swirled through the batter for pockets of molten hazelnut chocolate

Pro Tips
- Don’t overmix the batter — stir just until the flour disappears to keep the texture light and fluffy, not rubbery
- Use a 12-ounce mug minimum — the cake rises dramatically and needs room to expand without overflowing
- Swirl, don’t stir in the Nutella — drop spoonfuls on top of the batter and gently swirl with a knife for those gorgeous molten pockets instead of blending it completely in
- Let it rest 30 seconds after microwaving — the cake continues cooking from residual heat and firms up just enough to hold together
Single Serve Nutella Hazelnut Mug Cake
Ingredients
Method
- In a 12-ounce or larger microwave-safe mug, whisk together the flour, sugar, cocoa powder, baking powder, and salt with a fork until no lumps remain.
- Add the milk, oil, and vanilla extract to the dry ingredients. Stir gently with the fork just until the batter comes together and no dry flour is visible, about 10-15 strokes.
- Drop the Nutella in small spoonfuls on top of the batter. Use a knife or skewer to gently swirl it through the batter in a figure-eight motion, creating ribbons without fully mixing it in.
- Microwave on high power for 60-90 seconds, checking at 60 seconds. The cake is done when the top looks set and springs back lightly when touched. It will rise up significantly during cooking.
- Let the mug sit for 30 seconds to finish cooking from residual heat. The cake will deflate slightly and firm up. Top with extra Nutella, whipped cream, or ice cream if desired, then enjoy straight from the mug.
Frequently Asked Questions
Can I use another hazelnut spread instead of Nutella?
Yes, any chocolate hazelnut spread works beautifully. Just make sure it’s creamy and spreadable at room temperature for the best swirls.
Why did my mug cake turn out rubbery?
Overmixing the batter or microwaving too long are the usual culprits. Stir just until combined and start checking at 60 seconds, as microwave power varies.
Can I make this without a microwave?
Absolutely. Bake it in a small ramekin at 350°F for 12-15 minutes, or until a toothpick comes out with just a few moist crumbs.
How do I store leftovers?
This cake is best enjoyed immediately while warm and fluffy. It firms up and loses its magic texture once cooled, so treat yourself to the whole mug.
Storage & Serving
This treat is designed to be devoured fresh from the microwave while the Nutella is still molten. If you must save it, cover and refrigerate for up to 24 hours, then reheat for 20-30 seconds. Top with a dollop of whipped cream, a scoop of vanilla ice cream, or a drizzle of extra Nutella for an over-the-top indulgence.
