Peanut Butter Rice Krispie Treats Recipe
Introduction
Peanut Butter Rice Krispie Treats are a delightful twist on the classic childhood favorite. With rich brown butter, creamy peanut butter, and pockets of marshmallow, these treats offer a perfect balance of flavors and textures that 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 with parchment paper. Set aside.
- Step 2: Brown the butter by melting it in a large, light-bottomed Dutch oven over medium heat. The butter will foam and then the foam will subside as tiny brown specks form at the bottom. Stir constantly with a heat-resistant spatula or wooden spoon to prevent sticking. This browning adds a rich, nutty flavor.
- Step 3: When the butter turns chestnut brown and smells nutty, add 6 cups of the mini marshmallows. Stir with a wooden spoon until melted, then remove from heat and turn off the burner.
- Step 4: Stir in the vanilla extract and salt, followed by the peanut butter until smooth and well combined.
- Step 5: Add the Rice Krispie Cereal and stir thoroughly with a wooden spoon or rubber spatula. The mixture will be sticky, so keep stirring until evenly coated.
- Step 6: Fold in the remaining 2 cups of mini marshmallows gently, leaving small pockets of marshmallow throughout.
- Step 7: Transfer the mixture into the prepared pan. Gently press down using the back of the butter wrapper or a greased spatula. Avoid compacting too tightly to keep the treats light and chewy.
- Step 8: Garnish with flaky sea salt or drizzle with melted dark chocolate for an extra touch of indulgence.
- Step 9: Let the treats cool at room temperature for 30 to 60 minutes. Cover if left out longer than an hour to keep them fresh.
- Step 10: Lift the bars out of the pan, place on a cutting board, and cut into squares. Enjoy!
Tips & Variations
- Swap peanut butter for cookie butter or almond butter to vary the flavor.
- Try adding chopped nuts or chocolate chips for extra texture.
- Use parchment paper with a slight overhang to easily lift treats from the pan.
- Press the mixture lightly to keep a chewy, marshmallowy texture rather than hard bars.
Storage
Store treats in an airtight container at room temperature for up to 3 days. For longer storage, refrigerate them for up to a week. To enjoy after chilling, allow them to come to room temperature or microwave briefly for a soft texture.

FAQs
Can I use crunchy peanut butter instead of creamy?
Yes, crunchy peanut butter works well and adds a bit of extra texture to the treats.
What can I do if my treats are too sticky?
If the mixture is too sticky to handle, refrigerate it for 15-20 minutes before pressing into the pan. This helps it firm up without losing chewiness.
