Sometimes you just want something chocolatey and warm, and you want it now. Not in an hour, not after a trip to the store.

That’s exactly why I love this gluten free Nutella mug cake. It takes about 5 minutes from start to finish, and all you need is a mug and a microwave.

The Nutella gives it this rich, hazelnut chocolate flavor that makes it feel way more special than a simple mug cake. And yes, it’s completely gluten free, so you don’t have to worry about that.

You probably already have most of the ingredients at home. Some gluten free flour, cocoa powder, an egg, a little milk and oil, and of course Nutella. That’s it.

It’s the kind of recipe you’ll come back to over and over. Perfect for late night cravings or when you just need a quick treat without making a whole cake.

Single Serving Perfection – Because it’s made in a mug, you get just enough cake for one person. No leftover cake sitting on the counter tempting you all week long.

How to Make

Step 1

In a large microwave-safe mug, whisk together gluten free flour, sugar, cocoa powder, and baking powder.

Step 3

Drop the Nutella into the center of the batter, but do not stir it in.

Step 4

Microwave on high for 60-90 seconds, depending on your microwave power, until the cake has risen and is set on top.

Step 5

Let cool for 1 minute before enjoying directly from the mug or turning out onto a plate.

Helpful Tips

Use a Big Enough Mug

This matters more than you think. The batter rises a lot in the microwave, and if your mug is too small it will overflow and make a mess. Go with a mug that holds at least 12 ounces.

A standard coffee mug is usually fine, but those smaller espresso-style cups or thin mugs won’t work. You want the batter to fill the mug only about halfway before it goes in the microwave.

If you’re not sure about the size, you can always test by filling your mug with water and pouring it into a measuring cup to check.

Whisk the Dry Ingredients First

Before you add the egg, milk, and oil, take a moment to really mix the flour, sugar, cocoa powder, and baking powder together. This makes sure the baking powder is evenly spread through the dry mix so the cake rises evenly.

If the baking powder stays clumped in one spot, you might get one part of the cake that puffs up a lot and another part that stays flat and dense. A quick 15-second whisk with a fork will do the job.

Get the Batter Completely Smooth

When you add the wet ingredients to the dry mix, really take your time whisking. Gluten free flour can be a little stubborn and tends to clump up more than regular flour, especially at the bottom of the mug where it’s hard to reach.

Use a fork or a small whisk and scrape along the bottom and sides of the mug. You want a smooth, pourable batter with zero dry pockets hiding anywhere.

If you skip this step, you’ll bite into little pockets of dry flour in the finished cake and the texture won’t be right.

Frequently Asked Questions

How long do I microwave this Nutella mug cake?

Microwave it for about 1 minute and 30 seconds to 2 minutes on high power. Every microwave is a little different, so start with 1 minute and 30 seconds and check it – if the top still looks wet, add 15 seconds at a time until it looks set.

You want the cake to be slightly moist in the center, not dry. It will continue to firm up a little after you take it out, so don’t overdo it or it can turn rubbery.
