Step‑by‑Step Instructions for Peanut Butter Rice Krispie Treats
Step 1: Prep the Pan
Start by preparing a 9×13-inch baking pan. Line the bottom and sides with aluminum foil or parchment paper, leaving some overhang for easy removal later. Generously spray the lining with nonstick cooking spray to prevent sticking, ensuring your Peanut Butter Rice Krispie Treats release easily once set.
Step 2: Melt Ingredients
In a large pot, over medium-low heat, melt ½ cup of unsalted butter. Once it’s all melted and bubbly, add in 1 cup of creamy peanut butter and stir continuously until the mixture is smooth and fully combined. This should take about 1-2 minutes; remove from heat to prevent burning.
Step 3: Add Marshmallows
Stir in 15 ounces of marshmallows into the melted peanut butter mixture while keeping the heat on medium-low. Continue to stir for about 3-5 minutes until the marshmallows are completely melted and the mixture is smooth. It should be glossy and sticky, with no lumps, creating a delightful base for your treats.
Step 4: Mix in Vanilla
Once the marshmallows have melted into a creamy texture, remove the pot from heat. Stir in 1 teaspoon of vanilla extract, mixing thoroughly to incorporate the flavor into the warm mixture. This step enhances the overall taste of your Peanut Butter Rice Krispie Treats and adds a lovely aroma.
Step 5: Combine with Cereal
While the mixture is still warm, gently fold in 6 cups of Rice Krispies cereal. Use a spatula to ensure each piece gets coated evenly without crushing the cereal. This should take about 1-2 minutes, as the warm mixture helps bind everything together, forming a delicious and crunchy texture.
Step 6: Press into Pan
Carefully transfer the Rice Krispie mixture into the prepared baking pan. Using a greased spatula or a piece of wax paper, press down firmly but evenly until the mixture is smooth and level. Ensure it's tightly packed for the best texture when slicing your Peanut Butter Rice Krispie Treats.
Step 7: Set and Slice
Allow the mixture to cool at room temperature for about 30 minutes or until it is set. Once cooled, use the overhanging foil or parchment to lift the slab out of the pan. Slice it into bars or squares, and your Peanut Butter Rice Krispie Treats are ready to be enjoyed or stored!

Peanut Butter Rice Krispie Treats Recipe FAQs
How do I choose the right marshmallows?
Absolutely! For the best results, I always recommend using fresh marshmallows. They should be soft and springy to the touch. If they are hard or have dark spots all over, they may not melt properly and can affect the texture of your Peanut Butter Rice Krispie Treats.
What’s the best way to store leftovers?
Very good question! To keep your Peanut Butter Rice Krispie Treats fresh, store them in an airtight container at room temperature for up to 3 days. If you'd like them to last longer, you can refrigerate them for 5-7 days. Just be aware that refrigerating can make them a bit firmer; letting them sit at room temperature for a few minutes before enjoying will soften them up.
Can I freeze Peanut Butter Rice Krispie Treats?
Yes! Freezing is a great option for long-term storage. To do this, wrap individual bars in wax paper, then place them in an airtight container. Your treats can be stored in the freezer for up to 3 months. When you’re ready to enjoy one, just thaw them at room temperature or microwave for 10-15 seconds to revive that wonderful gooeyness.
What if my mixture is too sticky?
If you find the mixture is too sticky to handle, don't worry! A simple trick is to wet your hands with a little water or spray your spatula with nonstick cooking spray. This will prevent sticking and help you press the mixture into the pan evenly without too much mess.
Are there any dietary considerations I should be aware of?
Absolutely! If you're making these treats for someone with gluten sensitivities, be sure to use gluten-free Rice Krispies. Additionally, consider checking the peanut butter for any added ingredients that might cause allergies, and if nuts are included as mix-ins, make sure everyone enjoying the treats is aware of those allergies.
Can I substitute ingredients in this recipe?
Of course! This recipe is wonderfully adaptable. For example, if you prefer using crunchy peanut butter for added texture, feel free to swap that in. You can also mix in mini chocolate chips, dried fruits, or chopped nuts to tailor it to your taste preferences. The more, the merrier!
