Step‑by‑Step Instructions for Peanut Butter Rice Krispie Treats
Step 1: Prep the Pan
Start by lining a 9×13-inch baking pan with parchment paper or aluminum foil to prevent sticking, and then spritz it lightly with nonstick cooking spray. This step is crucial for making sure your Peanut Butter Rice Krispie Treats lift out easily once set, ensuring a smooth removal and clean presentation for your delicious creation.
Step 2: Melt Ingredients
In a large saucepan, melt ½ cup of unsalted butter over medium-low heat. As the butter begins to foam, stir in 1 cup of creamy peanut butter, mixing until you achieve a creamy and smooth consistency. This should take about 2-3 minutes. Keep stirring until everything is well combined and the mixture is luscious and free of lumps.
Step 3: Add Marshmallows
Next, pour in 15 ounces of marshmallows into the warm peanut butter mixture. Stir continuously for about 3-5 minutes until the marshmallows are completely melted and the mixture is smooth and glossy. You’ll see the transformation as the marshmallows blend into the rich, gooey base, creating that irresistible texture for your Peanut Butter Rice Krispie Treats.
Step 4: Mix in Vanilla
Remove the saucepan from the heat, and quickly stir in 1 teaspoon of pure vanilla extract for an added depth of flavor. The warm mixture will absorb the vanilla beautifully, enhancing the overall taste of your treats. Make sure it’s evenly mixed for a delightful burst of flavor in every bite of your Peanut Butter Rice Krispie Treats.
Step 5: Combine with Cereal
Carefully fold in 6 cups of Rice Krispies cereal into the peanut butter and marshmallow mixture. Use a spatula to gently mix until all the cereal is evenly coated, ensuring that no dry cereal remains. This process should take about 2-3 minutes. The mixture should appear sticky and clump together beautifully, perfect for your no-bake treats.
Step 6: Press into Pan
Transfer the sticky mixture into your prepared pan. Using a greased spatula or your clean hands, press it down firmly and evenly into the pan to ensure it sets well. This is an essential step, as even pressure helps the bars hold their shape. Make sure the surface is smooth for an appealing finish on your Peanut Butter Rice Krispie Treats.
Step 7: Set and Slice
Allow the Peanut Butter Rice Krispie Treats to cool at room temperature for about 30 minutes, or until they are firm. Once set, gently lift the entire treat from the pan using the edges of the parchment or foil. Slice into bars with a sharp knife. The treats should be thick, chewy, and slightly sticky, ready to be enjoyed!
How to Store and Freeze Peanut Butter Rice Krispie Treats
Room Temperature: Keep the treats in an airtight container at room temperature for up to 3 days to maintain their chewy texture and flavor.
Fridge: For extended freshness, refrigerate the bars in an airtight container for up to a week; they can become a bit firmer when chilled but are still delicious.
Freezer: Freeze individual bars in a single layer, then transfer to a resealable freezer bag for up to 3 months; defrost at room temperature or microwave for a few seconds before enjoying.
Reheating: If refrigerated, briefly warm them in the microwave for 10-15 seconds to revive their gooey texture and enhance the flavors in your Peanut Butter Rice Krispie Treats.

Peanut Butter Rice Krispie Treats Recipe FAQs
How do I select the best marshmallows for Peanut Butter Rice Krispie Treats?
Absolutely! Always choose fresh, soft marshmallows without any dark spots, as they melt better and provide that gooey texture you’re looking for. If marshmallows are stale or hard, they won’t melt properly and can create lumps in your treats.
Can I store Peanut Butter Rice Krispie Treats, and how long will they last?
Very! Store your Peanut Butter Rice Krispie Treats in an airtight container at room temperature for up to 3 days. If you prefer, they can also be refrigerated, where they will stay fresh for about a week; just keep in mind they might become a bit firmer when chilled.
What’s the best way to freeze Peanut Butter Rice Krispie Treats?
Certainly! To freeze, first slice the treats into bars and lay them in a single layer on a baking sheet, ensuring they aren't touching. Once they are frozen solid (about 1-2 hours), transfer the bars to a resealable freezer bag or airtight container. They can be stored in the freezer for up to 3 months. When ready to enjoy, simply defrost at room temperature or pop them in the microwave for 10-15 seconds.
What should I do if my Peanut Butter Rice Krispie Treats are too sticky?
Don't worry! If your treats turn out too sticky, it could be due to over-melting the ingredients. To troubleshoot, make sure to melt the butter and peanut butter just until smooth and then add the marshmallows right away. Also, pressing the mixture into the pan too firmly can add to stickiness, so use a greased spatula or your hands to flatten them gently without compressing too much.
Can I modify this recipe for dietary restrictions?
Absolutely! For gluten sensitivities, simply use gluten-free Rice Krispies. If you're catering to nut allergies, you can replace peanut butter with sun butter or soy nut butter. Always check labels for any hidden allergens, especially in marshmallows and other mix-ins.
How can I customize my Peanut Butter Rice Krispie Treats?
Very easy! Mix-ins are a fun way to customize your treats. Options like mini chocolate chips or crushed graham crackers can give a different flavor profile. If you're adventurous, try adding dried fruits or a sprinkle of sea salt on top for a sweet-and-savory combo. Just remember to adjust the amount of Rice Krispies accordingly to keep the texture balanced.
