How to Make Peanut Butter Krispie Brownies

These layered brownies are very easy to make with only a few simple ingredients. Start with preparing a box of brownie mix. In a bowl, add the brownie mix, eggs, oil, and water called for on the package. Mix together with a wooden spoon. Pour the batter into a 9×13-inch baking pan and bake in the oven according to the package directions. Let the brownies cool completely on a wire rack. Use a spatula to spread a jar of marshmallow creme over the brownies. 

In a medium saucepan over low heat, melt peanut butter and chocolate chips, stirring until smooth. Remove from heat and gently stir in Rice Krispies. Spread the chocolate peanut butter mixture over the marshmallow creme. Cover and chill. Cut into squares and enjoy.

Tips & Frequently Asked Questions

  • I used boxed brownie mix for this recipe. You can substitute your favorite scratch brownie recipe. Here is our favorite recipe for homemade brownies: https://www.plainchicken.com/bisquick-brownies/
  • You will need to double the recipe and bake in a 9×13-inch pan.
  • I leave out the walnuts or pecans when I use this homemade brownie recipe in this dessert.
  • I used Jif smooth peanut butter. You can use any brand of peanut butter that you enjoy. Smooth or crunchy works just fine. ​
  • I used semi-sweet chocolate chips. Milk chocolate or dark chocolate chips would also work great.
  • I melted the peanut butter and chocolate on the stovetop, but you can also melt them in the microwave.
  • How do I know if my brownies are done? Bake the brownies until a toothpick inserted into the center of the brownies comes out clean or with only crumbs, no batter on it.
  • My biggest tip for making these brownies is to line your pan with parchment paper or aluminum foil before baking the brownies.
    • You want the parchment paper to hang over the edges a bit. This will help you when you go to get the brownies out of the pan. I run a knife around the sides of the pan before lifting them out of the pan.
  • You can cut the recipe in half and make the recipe in an 8-inch or 9-inch square pan.
  • How to store brownies? Store the brownies in an airtight container on the countertop.
    • If it is warm outside, store the brownies in the refrigerator so the chocolate and marshmallows are firm.
  • How long do brownies keep? The brownies will keep for 3 to 4 days in an air-tight container.

  1. Just want you to know I made these for a cookie exchange/competition with over 50 friends and I won first place with these!! Thank you!

  2. These are great. I live in Mexico City and you can’t find marshmallow creme here so I’m going to try it with regular marshmallows and put it in the oven to melt a bit.

    I make these the night before so the krispy layer has time to harden. I would not recommend making them the same day you’re going to serve them.

  3. These were so easy to make! I will find out if they are a hit tonight at our potluck!
    I think the only thing I may change is the Krispy layer as it does not seem to 'harden' so it is messy. Not sure if I did something wrong but I'll tweak it to see how to harden it…maybe less peanut butter.
