Keto peanut butter and chocolate cake – where have you been all my life?  If chocolate and peanut butter are a combination that makes your heart (and stomach) race, then you’ll love this creamy, decadent low-carb cake with a chocolate and peanut butter cookie crust.   Seriously. ? ????

Honestly, chocolate and peanut butter is the combination I’ve always talked about.  It’s not that I don’t like it, it’s just that I don’t have the lasting love that some bloggers have for it.  So there are not many desserts at IBIH that combine these two qualities.

But it doesn’t matter, because honestly, this chocolate peanut butter keto cake is the only recipe you need to get the best of both, in my opinion.  A rich and creamy peanut butter filling combined with a crispy chocolate cookie crust and topped with a drizzle of dark chocolate and a lightly sweetened peanut butter sauce…. And the roasted peanuts on top! ? Hold still, honey.

I can’t decide if I prefer this chocolate peanut butter pie frozen or just chilled.  I like cream when it’s soft enough to melt in my mouth, and ice cream, like the quality of peanut butter and filling when it’s mostly frozen.

I leave it to you to try both methods and see which you prefer!

You should know that this chocolate and peanut butter cake is pretty easy to make.  Just push the crust in, without rolling it, and it only needs to bake for about 10 minutes – which is all you need for this almost no-bake keto peanut butter pie.

The filling is an ultra creamy combination of peanut butter, vanilla, sweetener, whipped cream and mascarpone cheese (you can use cream cheese, but I don’t like it).

The crunchy filling is optional, but it adds so much flavor and texture that I highly recommend going ahead – and it’s also a great side dish.

I could go on and on listing all the reasons why you should IMMEDIATELY make this Peanut Butter Chocolate Keto Cake, but honestly, if you’re not already, I don’t know how much more I can say about it to convince you!

If you make that chocolate peanut butter pie, make sure you spread the word and let everyone know how it was – maybe your words are just a shock to the people on the fence and should be.
