    Fudgy and decadent, these Peanut Butter Swirl Brownies are the ultimate treat. Gluten-free, grain-free, and dairy-free.

    peanut-butter-brownies-11This 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.

    Peanut Butter Swirl Brownies (Gluten-Free, Dairy-Free) | saltedplains.comA 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 this 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.

    Ingredients

    Brownie batter:

    • 6 tablespoons coconut oil
    • ⅓ cup arrowroot starch/flour I like Bob's Red Mill Brand, cornstarch works here as well
    • ¼ cup unsweetened cocoa powder
    • ½ teaspoon salt
    • 12 ounces dairy-free chocolate chips
    • ¾ cup organic coconut palm sugar
    • 1 teaspoon pure vanilla extract
    • 3 large eggs room temperature

    Peanut Butter Swirl:

    • ⅓ cup all-natural peanut butter should be stirred well
    • 1-2 teaspoons honey
    • pinch of salt
    • ⅛ teaspoon pure vanilla extract

    Instructions

    • Preheat oven to 350 degrees. Grease an 8-inch baking pan with coconut oil and line with parchment paper.
    • Whisk together arrowroot powder, cocoa powder, salt and set aside.
    • In a large microwave-safe bowl, combine the chocolate chips and coconut oil. Microwave in 30 second intervals, stirring each time, until almost all chips have melted. Stir until smooth and allow to cool for a minute or two before next steps.
    • Stir in coconut sugar and vanilla. Stir in eggs, one at a time, until combined.
    • Add arrowroot powder mixture and mix well until combined and smooth.
    • In a small bowl, combine ingredients for peanut butter swirl and mix well.
    • Pour batter into pan and smooth top. Drop tablespoons full of the peanut butter mixture on top of batter. Using an offset spatula or butter knife to swirl the batters together in a loose figure-8 pattern. Bake until a toothpick comes out clean, for 30 to 35 minutes, making sure to rotate hallway through.
    • Let cool completely on wire rack before cutting into squares. Store in an airtight container.

      I love this recipe and have made it a dozen times. I'm thinking about doing a coconut butter (manna) swirl instead of pb. Wondering if anyone has an opinion on how this could work? Thanks!

      New favorite brownie recipe. Easy and so fudgy! A big hit with multiple groups and the gluten-free aspect doesn't even come up. I sub butter for coconut oil usually. I might try with a mochi flour that I have on hand to see if it makes it even chewier, just for fun. Thank you so much for this!

      Hi! this looks amazing! I wish to make this in near future and is wondering if any other flour (oat flour, ground almond, or anything) else could be substituted for starch or constarch. And if possible how would it effect the taste and texture? Also I am curious if the peanut butter taste is subtle or strong in this brownie! I want to make something very peanutbuttery.. Thank you! :)

      These look incredible! I would love to try these with some other flavored butter, like vanilla almond...and I say I would like. I won't, or I'd polish them all in one sitting and that's no good.
      Pinned anyways (you never know!) :)

      I wish we could send each other food via some special Missouri east to west zipline. I really want these in my life. I will have to muster the strength to bake, xx.

      any recommendations on making these vegan? I think I'll try flax eggs and see if that works out :)

        Flax eggs would probably be where I would start as well. I'd love to hear if that worked for you! xo
