Gluten Free Peanut Butter Swirl Brownies

This last weekend we spent some time with dear friends in Asheville, North Carolina. One evening, we were discussing “last meal-worthy” foods. While my last meal would probably consist of pizza, without a doubt, my last dessert would be these peanut butter swirl brownies.

A true treat for me is anything in the peanut butter-chocolate family, and brownies will always top the list. These brownies are adapted from a flourless brownie recipe from the early days of my blog.

Made simply from cocoa powder, chocolate chips, arrowroot starch (or cornstarch), eggs, and topped and swirled with all-natural peanut butter sweetened with just a touch of honey—these brownies are likely to become a go-to.

And while the brownies are a decadent, fudgy treat, the swirling is pretty darn gratifying as well. Enjoy!
