Chocolate Peanut Butter Marshmallow Treats


These easy no bake marshmallow treats are like extra gooey rice krispie treats with chocolate and peanut butter melted in! They’re so quick to make but yield a thick and rich marshmallow treat that tastes way better than any basic version.


  • 1 cup (250g) creamy peanut butter (plus 2 tbsp to drizzle)
  • 1 cup (185g) semisweet chocolate chips
  • 1/2 cup (110g) unsalted butter
  • 1 10oz bag mini marshmallows
  • 1 tsp vanilla extract
  • 4 cups (120g) puffed rice cereal *GF option here


  1. Grease and line an 8×8 pan with parchment paper. Allow the paper to reach over the edges of the pan for easy removal.
  2. In a large pot over medium heat, melt down the peanut butter, chocolate, and butter.
  3. Add in the marshmallows and continue to stir until melted and smooth.
  4. Remove from heat and stir in the vanilla, followed by the rice cereal.
  5. Dump the mixture into the prepared pan and press it in evenly.
  6. Chill the bars for about 45 minutes or until set.
  7. When you’re ready to serve, melt the 2 tablespoons of peanut butter in the microwave then drizzle over top. Cut into 9 large bars or 16 small bars and enjoy!


GLUTEN FREE CEREAL OPTIONS – Sadly, most puffed rice cereals are not gluten free but some still are! If you’d like to make these gluten free, choose a certified gluten free puffed rice cereal or swap in rice chex instead.
