Get ready to fall in love with a nostalgic classic, leveled up with a nutty twist—Peanut Butter Rice Krispies Treats! These no-bake bars combine gooey melted mini marshmallows, creamy peanut butter, and crunchy Rice Krispies cereal for the ultimate crowd-pleasing treat. Infused with a touch of vanilla and a pinch of salt for perfect balance, these squares are soft, chewy, and irresistibly delicious. Customize your treats with an optional drizzle of melted milk chocolate to add a decadent finish. Perfect for quick dessert cravings, lunchbox surprises, or potluck hits, this recipe comes together in just 15 minutes and offers pure, peanut-buttery bliss in every bite.
Grease a 9x13-inch baking dish lightly with butter or line it with parchment paper for easy removal of the treats.
In a large pot over medium heat, melt the unsalted butter until fully liquid.
Add the mini marshmallows to the pot and stir continuously until fully melted and smooth.
Reduce the heat to low and stir in the creamy peanut butter until well combined with the marshmallow mixture. Add a pinch of salt for flavor balance.
Remove the pot from the heat and stir in the vanilla extract.
Quickly fold in the Rice Krispies cereal, stirring gently with a spatula until the cereal is completely coated in the marshmallow mixture.
Pour the mixture into the prepared baking dish and press it down gently with a spatula to create an even layer. Be careful not to compress it too much, as this will make the treats too dense.
If desired, drizzle the melted milk chocolate over the top of the treats for added richness.
Allow the Peanut Butter Rice Krispies Treats to cool at room temperature for about 30 minutes or until set.
Once cooled, cut the treats into 12 equal squares and serve. Store leftovers in an airtight container at room temperature for up to 4 days.
