I’m always looking for super easy and decadent keto desserts to have when I am craving sweets or just to enjoy it on a cold Sunday morning.

When I’m sharing a recipe with you on this blog I have to make sure it is super easy to make and with ingredients that can be found at any food store. Nothing too complicated, but the result is fantastic.

To be honest I only ate lava cake at restaurants and it comes with vanilla ice-cream on top. I had the classic chocolaty one and vanilla lava cake but never had classic peanut butter chocolate lava cake before keto.

Chocolate and peanut butter are just meant for each other. You just can’t go wrong with this Keto recipe.

I’m so enthusiast about sharing the recipe with you. The serving size is huge and satisfying. It will keep you full for such a long time.

If you are not a peanut butter fan you can try my simple keto lava cake that’s also insanely delicious and easy to make.
