Butter and Marshmallow Mixture
- 1/2 cup unsalted butter
- 8 cups mini marshmallows, divided (6 cups + 2 cups)
- 3/4 cup creamy peanut butter (or cookie butter!)
- 2 tsp vanilla extract
- 1/2 tsp salt
Cereal
- 6 cups Rice Krispie Cereal
Garnish
- Flaky sea salt (optional)
- Melted dark chocolate (optional)
- Prepare the Pan: Lightly grease a 9×9 inch pan with baking spray or line it with parchment paper. Set aside for later.
- Brown the Butter: In a large, light-bottomed Dutch oven over medium heat, melt the butter. Stir constantly with a heat-resistant spatula or wooden spoon to evenly brown the milk solids. Watch for the butter to turn chestnut brown and emit a nutty aroma, about 5-7 minutes.
- Melt Marshmallows: Immediately add 6 cups of the mini marshmallows to the browned butter. Stir until the marshmallows are fully melted and the mixture is smooth, then remove from heat and turn off the burner.
- Mix in Flavorings: Stir in the vanilla extract and salt to the marshmallow mixture. Follow by stirring in the creamy peanut butter until completely combined.
- Add Cereal: Incorporate the Rice Krispie cereal into the marshmallow mixture using a wooden spoon or rubber spatula. The mixture will be sticky; continue stirring until the cereal is evenly coated.
- Fold in Remaining Marshmallows: Add the remaining 2 cups of mini marshmallows and gently fold them in, leaving some pockets of marshmallow intact for texture.
- Transfer to Pan and Press: Transfer the mixture into the prepared pan. Using the back of the butter wrapper or a greased spatula, gently press the mixture down lightly—avoid compacting tightly to maintain the chewy texture.
- Optional Garnish: Sprinkle flaky sea salt or drizzle melted dark chocolate over the top for added flavor contrast.
- Cool: Allow the treats to cool at room temperature for 30 to 60 minutes. Cover if leaving out longer than an hour to prevent drying.
- Cut and Serve: Lift the bars out of the pan, place on a cutting board, and cut into bars. Serve and enjoy your delicious peanut butter Rice Krispie treats!
Notes
- Use light-colored or a light-bottomed pot to monitor the browning of butter closely and prevent burning.
- Press the mixture lightly in the pan to keep the bars chewy and not too dense.
- Adding the final marshmallows last means you get little pockets of gooey texture in the bars.
- Store leftover bars in an airtight container at room temperature for up to 3 days.
- Gluten-free Rice Krispie cereal can be used for a gluten-free version of this treat.
- You can substitute peanut butter with cookie butter for a different flavor profile.
