Peanut Butter Swirl Brownies

Peanut Butter Swirl Brownie Recipe by Cashmere & Cocktails

While there is certainly no bad brownie, there’s something to be said about the combination of salty peanut butter and fudgy chocolate. I went ahead and tried to make them healthy-ish by using Fatso Classic High-Performance Peanut Butter which is packed with plant based superfats, as well as chia and flax seeds (this makes my recipe healthy, right? Right???). If you don’t have any Fatso on hand (though I highly recommend picking some up because it’s AH-mazing), this recipe totally works with regular peanut butter as well, so feel free to substitute if necessary. Regardless which of the two you use, these Peanut Butter Swirl Brownies are A MUST.
