Ingredients You’ll Need

- ½ cup unsalted butter: Adds richness and helps melt the marshmallows evenly for that classic gooey base.
- 1 cup creamy peanut butter: Brings the star nutty flavor and extra creaminess that elevates these treats beyond ordinary.
- 2 teaspoons pure vanilla extract: Enhances the overall sweetness and adds a subtle aromatic depth.

How to Make Peanut Butter Rice Krispie Treats Recipe
Step 1: Prep Your Pan
Start by lining a 9×13 inch baking pan with parchment paper or lightly greasing it with butter. This step ensures your treats will come out cleanly and keep their perfect shape once set.
Step 2: Melt the Butter
Place a large pot over medium heat and melt the softened butter. Once melted, reduce the heat to low to prepare for mixing without burning any ingredients.
Step 3: Add Peanut Butter and Vanilla
Stir the creamy peanut butter and pure vanilla extract into the melted butter. Keep stirring until the mixture is completely smooth and well combined. This step creates the luscious base flavor that defines this Peanut Butter Rice Krispie Treats Recipe.
Step 4: Melt the Marshmallows
Lower the heat to avoid scorching, then add your mini marshmallows to the pot. Stir constantly to melt them evenly until the entire mixture is thick, smooth, and glossy. This gooey marshmallow blend is what gives the treats their chewy, irresistible texture.
Step 5: Combine with Rice Krispies Cereal
Remove the pot from heat and gently fold the Rice Krispies cereal into the marshmallow mixture. Stir carefully until every crispy kernel is coated with that delectable peanut butter-mallow mixture. This ensures each bite is a perfect balance of crispy and soft.
Step 6: Set and Cool
Transfer the mixture into the prepared pan and spread it evenly using a buttered spatula or your fingers. Allow it to sit for about 30 minutes so it can firm up before you cut it into 24 perfect squares. This resting time is essential for that satisfying snap when you bite in.
How to Serve Peanut Butter Rice Krispie Treats Recipe

Garnishes
For an extra special touch, sprinkle a handful of mini chocolate chips or a drizzle of melted chocolate across the top before the treats set. You can also press some chopped peanuts on top for added crunch and visual appeal.
Side Dishes
These treats pair wonderfully with a cold glass of milk or a cup of hot coffee or tea, balancing out their sweetness perfectly. Serving alongside fresh fruit can also brighten the experience and add freshness to your snack time.
Creative Ways to Present
Cut the bars into fun shapes using cookie cutters for themed parties or wrap individual squares in parchment and tie with a cute ribbon for gifting. Stack them in a mason jar or a decorative tin for a charming homemade present that’s sure to impress.
Make Ahead and Storage
Storing Leftovers
Keep your Peanut Butter Rice Krispie Treats Recipe fresh by storing them in an airtight container at room temperature. They will stay soft and delicious for up to 3 days, making them perfect for preparing ahead of time.
Freezing
If you want to enjoy them later, freeze individual squares wrapped tightly in plastic wrap and placed in a freezer-safe bag. They can keep well for up to 2 months and thaw quickly at room temperature when you’re ready.
Reheating
To refresh frozen treats, a few seconds in the microwave can soften them slightly, bringing back that freshly made gooey goodness. Just be careful not to overheat, or they might become too sticky to handle.
FAQs
Can I use crunchy peanut butter instead of creamy?
Absolutely! Crunchy peanut butter will add a nice texture to the treats, giving them an extra bit of crunch that complements the crispy cereal perfectly.
Is there a substitute for mini marshmallows?
While mini marshmallows are ideal, you can substitute with large marshmallows, cutting them into smaller pieces to melt evenly. Avoid marshmallow fluff, as it doesn’t provide the same texture.
Can I use a different cereal instead of Rice Krispies?
Yes, you can try other crispy rice cereals or even puffed wheat, but keep in mind this will change the texture and flavor slightly from the original Peanut Butter Rice Krispie Treats Recipe.
How can I make these treats vegan?
Use a plant-based butter and vegan marshmallows that do not contain gelatin, and ensure your peanut butter is free from added non-vegan ingredients. This will make your treats both delicious and vegan-friendly.
What’s the best way to cut the treats cleanly?
Use a sharp knife and lightly grease or dampen it before cutting to prevent sticking. Cutting after the treats have set completely helps achieve neat, even squares.
Final Thoughts
There is something truly comforting about the combination of peanut butter and marshmallows wrapped in a crispy, chewy bar, and this Peanut Butter Rice Krispie Treats Recipe captures that magic perfectly. Whether you are making them for a party, a snack, or just because, these treats bring a smile with every bite. I can’t wait for you to make them and share the joy with your friends and family!
