Peanut Butter Rice Krispies Treats Recipe
Introduction
Peanut Butter Rice Krispie Treats are a delightful twist on a classic favorite. Combining the rich nuttiness of brown butter and peanut butter with the gooey sweetness of marshmallows, these treats offer a perfect balance of flavors and textures everyone will love.

Ingredients
- 1/2 cup unsalted butter
- 8 cups mini marshmallows, divided
- 3/4 cup creamy peanut butter (or cookie butter!)
- 2 tsp vanilla extract
- 1/2 tsp salt
- 6 cups Rice Krispie Cereal
Instructions
- Step 1: Lightly grease a 9×9 pan with baking spray or line it with parchment paper. Set aside.
- Step 2: In a large, light-bottomed Dutch oven over medium heat, melt the butter. As it melts, it will foam, then the foam will subside and tiny specks will appear. Stir constantly with a heat-resistant spatula or wooden spoon to prevent sticking and encourage browning.
- Step 3: Once the butter turns chestnut brown and smells nutty, add 6 cups of marshmallows. Stir until melted, then remove from heat.
- Step 4: Stir in the vanilla extract and salt, followed by the peanut butter. Mix until smooth.
- Step 5: Add the Rice Krispie cereal and stir with a wooden spoon or rubber spatula until fully combined. The mixture will be sticky.
- Step 6: Fold in the remaining 2 cups of mini marshmallows gently to leave small pockets throughout the mixture.
- Step 7: Transfer the mixture into the prepared pan. Gently press down using the back of a butter wrapper or a greased spatula. Avoid pressing too tightly for the best texture.
- Step 8: Garnish with flaky sea salt or drizzle with melted dark chocolate if desired.
- Step 9: Let the treats cool at room temperature for 30 to 60 minutes. Cover if leaving out longer than an hour.
- Step 10: Lift the treats out of the pan, place on a cutting board, and cut into bars. Enjoy!
Tips & Variations
- Use cookie butter instead of peanut butter for a unique flavor variation.
- Adding flaky sea salt on top balances the sweetness beautifully.
- Press the mixture gently to keep the treats light and airy, avoiding a dense texture.
- For a chocolate twist, drizzle melted dark chocolate over the top once pressed into the pan.
Storage
Store the treats in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. Reheat briefly in the microwave if you prefer them softer before serving.

FAQs
Can I use natural peanut butter instead of creamy peanut butter?
Yes, natural peanut butter will work, but it may make the mixture a bit less smooth. Stir it well before adding to ensure even incorporation.
Can I make these treats gluten-free?
Absolutely! Just make sure to use Rice Krispie cereal that is labeled gluten-free, as some brands contain malt flavoring derived from barley.
