  • Thoroughly grease or spray your 9×13 baking dish so the bars release easily.
  • Measure the Rice Krispies into a bowl beforehand to speed up mixing.
  • Line the measuring cup with plastic wrap or use a lightly greased cup when measuring peanut butter to remove it cleanly.
  • Melt marshmallows over medium-low heat to keep the texture soft and chewy—high heat can make them tough.
  • Use buttered hands, a butter wrapper, or a plastic bag over your hand to press the mixture evenly into the pan without sticking.

Loaded with marshmallows and peanut butter with just the right amount of vanilla and salt, these simple Peanut Butter Rice Krispie Treats are an easy family favorite.
Ingredients
  • 8 cups Rice Krispies cereal
  • 2–3 cups mini marshmallows
  • 1 (16 oz) bag full-size marshmallows
  • 1/3 cup salted butter
  • 3/4 cup creamy peanut butter
  • 1/4 tsp salt
  • 1 tsp vanilla
Instructions
  1. Measure 8 cups Rice Krispies into a bowl and set aside. Measure 2–3 cups mini marshmallows and set aside.
  2. Grease or spray a 9×13 baking dish and set aside.
  3. In a large (5- or 6-quart) pot, melt the 1/3 cup butter over medium-low heat. Add the 16 ounces of full-size marshmallows.
  4. Stir and melt over medium-low heat until marshmallows are half-melted, keeping heat gentle so the mixture stays soft and chewy.
  5. Add the peanut butter and salt, continuing to stir until the marshmallows are fully melted and the peanut butter is incorporated.
  6. Remove the pan from heat, stir in the vanilla, then quickly add the Rice Krispies. Stir briskly to coat all the cereal. Fold in the mini marshmallows until distributed.
  7. Transfer the mixture to the prepared 9×13 dish and press it firmly and evenly into the pan using buttered hands, a butter wrapper, or a plastic bag over your hand.
  8. Allow to cool completely for neat slices, or cut and enjoy while slightly warm if you prefer.
  9. Serve and enjoy.
