Peanut Butter-Chocolate Molten Lava Cake

by Erin

In case lava cakes weren’t indulgent enough, I present to you the peanut butter-chocolate molten lava cake. It’s chocolate cake with a creamy molten peanut butter center.

If you thought the s’mores lava cakes I made earlier this year were something to drool over, wait until you see these – peanut butter stuffed!

These lava cakes have been a staple sinful dessert in my life for several years now, and I have yet to not eat the entire cake by myself. Apparently someone out there thinks that there are two servings per lava cake. Granted, calorie-wise that person is probably not wrong, but let’s be honest. So this dessert could serve 8 people if they are able to resist the glory of what sits on a plate in front of them. But to me, placing two spoons by one of these cakes just means I have a spoon for each hand.

They look so innocent at first, even if you think they are just a regular lava cake. Until you cut into one and it’s true self is revealed. Hello lover! Oozing out with that creamy peanut butter goodness.

Of course, a REAL lava cake doesn’t have a pre-molten blob baked in the center. Lava cake is basically an undercooked cake where the center remains molten. Using a chocolate ganache center is cheating! So whenever I make traditional lava cake I do it right, but to make fun flavored ones you kind of do have to give in a cheat a little. Worth it.

Oh and of course… GO BUCKS!!!

Oooo, this is so evil! I would probably eat all eight cakes if left to my own devices!

It actually only makes 4, but two servings are in each! Hence why I think it’s impossible to only eat one serving.
