This flavor-rich dessert is also referred to as keto cake in a mug or keto mug cake.

Keto Chocolate Cake for One

Mug cakes are single-serving desserts with a cake-like texture.

You can quickly cook them in a microwave using mugs or a similar container.

That’s where the name, “keto chocolate mug cake” comes from.

Also, with just a few steps, you can have a delicious cake all to yourself.

And, since there’s only one serving, so you don’t have to worry about overindulging.

This treat is low-carb as well as gluten-free and paleo friendly.

So, the next time you need a little chocolate dessert, you have to try this easy-to-make treat.

Make a Chocolate Mug Cake in the Oven

If you want to use the oven instead of the microwave, you can still make this recipe in a matter of minutes.

Follow steps 1-4 in the recipe, making sure to use an oven-safe ramekin.

Then, bake at 350°F until the cake is set.

Be sure to check the cake after 5 minutes, and don’t cook it longer than 10 minutes.

The bake time maybe a bit longer, but you can still make a low carb, gluten free chocolate mug cake just as easily in the oven!
