Gluten Free Chocolate Peanut Butter PB2 Protein Cake

Gluten Free Chocolate PB2 Protein Cake

I love Pb2 and found it on sale at our local Big Lots of all places. I had never tried the chocolate flavor and found this to be the perfect opportunity to to grab a jar. I usually mix Pb2 and coconut oil to use as a dip for bananas. If you haven’t tried it it is divine.

I know the combination of chocolate, peanut butter and bananas is a popular one so I tried my fave snack with the chocolate PB2. I found the chocolate PB2 to be less peanut buter flavored and not as chocolatey as I thought it would be.

I knew I needed to use it up as I hate to waste ingredients. I started out attempting brownies, but ended up with an amazing protein packed chocolate peanut butter cake. I have tried protein cakes before and not cared for them as they were gritty, chalky, dry or wierdly flavored. This has all of the protein of a whole jar of PB2 and all of the flavor of rich chocolate peanut butter. The chocolate flavor really blossoms when more PB2 is used.

This recipe only has 1/4 cup of sugar in the whole thing. I still found it to be quite sweet for me and am sure the sugar amount could be decreased to 2 tablespoons if you like very lightly sweet desserts.
