Soft and moist Chocolate Eggless Mug Cake with a creamy Nutella filling, ready in just one minute in the Microwave! This is the perfect cozy treat that everyone will love.
If you don't have a microwave, you can also bake it in classic oven or an air fryer, you will just need some minutes more. In this case, I suggest to use a ramekin because the most of mugs are not oven-proof.
I used a 800W microwave: if you have a Microwave with higher/lower wattage, you have to reduce/increase the cooking time for few seconds; check out the top of the cake that should be dry when the cake is done (you can also check the mug cake with a skewer that would turn out clean).
The texture of the chocolate cake is incredibly moist and mud, rich and light since it doesn't feature egg, butter or milk.
Nutella is optional, you can simply make a chocolate mug cake and it will be delicious!

Hello, I am Valentina! Welcome to How Tasty!

I am an Italian girl in love with baking and cooking. I’ve been raised in a cooking family, baking since I was a little girl and learning from my mom and my professional chef grandma.

I created the Youtube channel How Tasty in 2017 to share with you my passion.

You don’t need to be a professional cook to follow all my recipes thanks to the video tutorials and the tips & hints you can find here.

Let’s cook!

Don’t lose any recipe!

Nutella is the perfect adding to this treat since it gives extra moist and sweet hazelnut flavor, an amazing match with chocolate batter!

When you put Nutella on top of chocolate batter, you just need to place some small batter amount on top to cover it a bit. You don’t need to place too much chocolate batter on top because Nutella is heavier than the cake batter and it will sink while cooking.

If you don’t like Nutella or you don’t have it in your pantry, you can just skip it, the chocolate mug cake will turn out irresistible!

Microwave cooks very fast, for this reason it’s the perfect tool you can use for cooking mug cakes, that are quick and easy treats.

I’ve used a Microwave 800 Watt power and my mug was ready in 55 seconds, less than 1 minute! If you have a Microwave with higher/lower wattage, you have to reduce/increase the cooking time for few seconds.

The cake is ready when the top is dry or, if you insert a skewer, it will turn out dry or just with some Nutella. Rememebr to check every tot. seconds your cake because microwave cooks fast and you don’t have to overcook your cake or it will turn out dry!

If you don’t have microwave, you can bake it in air fryer or traditional oven at 180°C-350°F for few minutes. If you decide to bake in classic oven or air fryer, remember to not use a simple mug but I suggest to use a ramekin that is surely oven proof.
