Peanut Butter Fudge Brownies

Addicted to chocolate…and peanut butter? ABK’s Peanut Butter Fudge Brownies filled with peanut butter chips,  topped with a  layer of peanut butter and chocolate buttercream frosting was made with you in mind! 


For as long as I can remember, I have loved Reese’s Peanut Butter Cups. I love them at room temperature, frozen, and even slightly melted.  I love the regular size (two to a package) and the smalls that are individually wrapped. Not a fan of the king size cups. Useless information, I know.

I’m also a huge fan of brownies and have posted at least a dozen different brownie recipes on this blog. What can I say, I’m definitely a brownie gal. This is the first time I’ve posted a brownie that has peanut butter chips in the batter. My Peanut Butter Cup Brownie Bites, are a bite size cookie I absolutely love. And my favorite peanut butter bakery cookie is Cutler’s Cookies Frosted Peanut Butter Cookie. It’s over the top delicious and the recipe comes straight from Curt Cuter, Cookie Boss of Bountiful, UT.  If you’re in Bountiful, you need to stop by and get either a Frosted Peanut Butter or a Brownie Marshmallow Cookie (those two are my favorites). Or just make a batch at home if you’re extra ambitious!


My recipe for Peanut Butter Fudge Brownies consists of  a fudge brownie, filled with peanut butter chips,  topped with a layer of smooth peanut butter (while the brownie is still hot), and finally, frosted with a thick layer of creamy chocolate frosting after the brownies have cooled off. It’s a peanut butter and chocolate lover’s dream.  If you love Reese’s, your’e going to love this recipe. Trust me, I know these things.

Happy baking!
