Jump to:
If you are looking for a sweet fix in just a couple of minutes this is the recipe for you! This cake takes 4 minutes in total and is made from only 4 ingredients. Does a cake get any easier than this?! Not only that, but it's NUTELLA! How can you go wrong with that sweet, chocolate hazelnut spread right...

List of Ingredients
Not only is this cake super quick and easy to make it only needs four ingredients! If you have self-raising flour you don't even need the baking powder. Simply use the same amount as you would plain flour.
- Nutella: This delicious chocolate hazelnut spread is perfect for making cake because it acts as the sugar and fat in the cake. This lets you bring the mug cake together with minimal ingredients. If you don't have nutella any other chocolate hazelnut spread should work just as well.
- Egg: The egg acts as a binding agent for the cake, bringing it all together and adding a little lightness.
- Flour: Flour is the gives the cake structure and body- essentially making it a cake!
- Baking powder: Baking powder is needed to give the cake rise, giving it that fluffy texture

Different Variations and toppings
This recipe makes that warm, and slightly gooey nutella cake base, but there are so many different ways you can dress this up! Here are a couple of my favourite suggestions.
- More nutella: An extra drizzle over the top of the cake adds to that gooeyness and creates an even more indulgent dessert
- Peanut butter: A drizzle of peanut butter over the top of these will transform them into a gooey chocolate peanut butter mug cake
- Chocolate chips: Mix chocolate chips into the batter for a double chocolate mug cake
- Fresh fruit: Break up the sweetness of the cake with some freshness. Fresh berries like strawberries, raspberries and cherries are the perfect match for anything chocolate
- Whipped cream: Whipped cream is a MUST! The light creaminess breaks up the sweetness, adds moisture and creates an all rounded dessert.
- Vanilla Ice cream: The ultimate combination. Warm, gooey chocolate cake and smooth and creamy ice-cream. The contrast in temperature and texture is what makes this the best collaboration.
- Cocoa powder: A dusting of cocoa powder over these mug cakes will give them an extra rich chocolatey touch
- Sprinkles: Top these off with sprinkles for a colourful and fun topping

Frequently Asked Questions
Can I use a different chocolate spread?
Yes definitely! There are so many Nutella alternatives out there these days, most of them are made from a similar composition of ingredients and will work perfectly in the place of Nutella.
My mug cake was dry
The cake may be dry if you left it in the microwave for too long or have let them sit for too long. These cakes are made to be eaten straight away, as the longer they sit the more they will dry out. These are so easy to put together so make them just before you're ready to eat!
Is the cake safe to eat with a molten centre?
Yes! At 2 minutes the bottom of the cake will be slightly molten, creating a delicious contrast in textures.
If you want the cake to be more gooey microwave it for 1 minute and 30 seconds. At this stage, the batter has been heated enough to be safe for consumption, so there won't be any problems eating it a little gooier!
How long does this last?
These are best eaten fresh as they are warm and gooey. Once they cool down they will lose some of that moisture, however, they'll be just as delicious
Can I make these ahead of time?
While you can make these ahead of time these are best when freshly made. If you are to make these ahead of time you can make the batter in the mugs and set them aside. When ready to serve simply place them in the microwave and zap!
Why did my mug cake become hard?
If you heat your mug cake for too long it'll become dry and hard. This might be because your microwave is more powerful. In that case, simply microwave your mug cake for a shorter amount of time.
How do you keep a mug cake moist?
The secret to a moist mug cake is in the cook time. Make sure you don't overcook your mug cakes as the longer you cook it the drier it'll become.
Once these cakes are microwaved they will be a little moist and gooey on the inside, however as they sit for another minute or so they will set up and become the perfect consistency!
These cakes are also better when they are a little gooey so I recommend keeping them that way!

I accidentally put way too little flour (1/4th of what was actually needed) but it still turned out really good!
