Peanut Butter Chocolate Rice Krispie Treats — Ingredient Highlights


Unsalted butter is my preference because peanut butter already contributes salt. If you only have salted butter, it will work — just taste before adding any extra salt. A sprinkle of flaky sea salt on top can be a nice finishing touch, but go light so the bars don’t become overly salty.

Creamy peanut butter blends smoothly into the marshmallow mixture, though crunchy peanut butter can be used if you want a little extra texture.

Mini marshmallows melt faster and more evenly, but jumbo marshmallows are fine if that’s what you have on hand.

For the chocolate coating, dark chocolate chips give a rich contrast to the peanut butter, but semi-sweet or milk chocolate chips will also work depending on how sweet you want the topping.

Tips and Tricks for Perfect Rice Krispies Treats with Peanut Butter and Chocolate


How to Make Chocolate Peanut Butter Rice Krispie Treats

Line your pan with parchment or wax paper for easy removal; alternatively grease the pan with butter or nonstick spray. For thicker bars, use an 8×8 or 9×9-inch pan. For thinner, more classic-sized bars, use a 9×13-inch pan.

On low-medium heat in a large pot, melt the butter. Add the peanut butter and stir until fully combined with the butter. Keep the heat low-medium and add the marshmallows, stirring continuously until they melt and form a smooth sticky mixture. Scrape the bottom of the pot as you stir so nothing sticks or burns.

Remove the pot from the heat and fold in the Rice Krispies cereal, coating it evenly with the peanut butter–marshmallow mixture. Work quickly but gently to avoid crushing the cereal — you want to retain the airy crispness.

Transfer the mixture to your prepared pan and press it in gently and evenly with a spatula. Don’t press too hard: pressing firmly makes the bars dense instead of light and airy. If the mixture is too sticky to handle, wet your hands lightly and shape the surface with gentle presses.

Melt the chocolate chips in a microwave-safe bowl in 30-second intervals, stirring between intervals until smooth. Pour the melted chocolate over the cereal layer and spread it into an even coating with a spatula. Let the chocolate set; placing the pan in the refrigerator speeds this up.

For a decorative peanut butter drizzle, warm 2 tablespoons of peanut butter for 10–15 seconds in the microwave to loosen it, then drizzle with a spoon. Finish with a small pinch of flaky sea salt if desired.

How to Store Chocolate Peanut Butter Rice Krispies

Store the finished treats in an airtight container at room temperature for up to 3 days. If you prefer a firmer chocolate topping or want them to last longer, refrigerate for up to one week. To freeze, place cut pieces in an airtight, freezer-safe bag and thaw before serving; they will keep for up to two months.

Equipment

  • Large pot
  • 8×8-inch or 9×9-inch baking pan (for thicker bars)
  • 9×13-inch pan (for thinner bars)

Ingredients

  • 5 tablespoons unsalted butter
  • 5 tablespoons peanut butter (creamy preferred)
  • 16 ounces marshmallows (about 8 cups)
  • 6 cups Rice Krispies cereal
  • 1 cup chocolate chips (dark, semi-sweet, or milk)

Instructions

  1. Grease or line a pan with parchment or wax paper. Use an 8×8 or 9×9-inch pan for thicker bars, or a 9×13-inch pan for thinner bars.
  2. In a large pot over low-medium heat, melt the butter completely (5 tablespoons unsalted butter).
  3. Add the peanut butter (5 tablespoons) and stir until combined.
  4. Add the marshmallows (16 ounces) and stir continuously until they melt and form a smooth mixture, scraping the bottom of the pot as needed to prevent sticking.
  5. Remove the pot from the heat and fold in the Rice Krispies (6 cups) until evenly coated.
  6. Transfer the mixture to the lined pan and press lightly to an even layer. If sticky, wet your hands slightly to smooth the surface; avoid pressing too hard.
  7. Melt the chocolate chips (1 cup) in 30-second intervals in the microwave, stirring until smooth. Pour over the bars and spread evenly.
  8. Allow the chocolate to set before slicing; refrigerating speeds the process.
  9. Optional: Warm 2 tablespoons of peanut butter for 10–20 seconds to loosen, then drizzle on top. Finish with flaky sea salt if desired.
