Sweet, salty, and perfectly chewy, these no-bake Chocolate Peanut Butter Rice Krispy Treats combine gooey marshmallows, creamy peanut butter, and crunchy pretzels for an irresistible treat that comes together in under an hour.
Melt butter, peanut butter, and marshmallows in a large pot until smooth.
Stir in vanilla, then fold in Rice Krispies until coated.
Press mixture evenly into a parchment-lined 9x13-inch pan. Let cool.
Melt chocolate in 30-second bursts and drizzle over the top.
Sprinkle crushed pretzels and halved mini Reese’s while the chocolate is still warm.
Allow chocolate to set, then cut into squares and serve.
Notes
Grease helps: Lightly oil your spatula (or hands) so the mixture doesn’t stick while pressing.
Don’t compact: Lightly press the mixture—just enough to level. Over-pressing makes dense, tough treats.
Add-ins timing: Fold candies/chips in after the marshmallow base cools 1–2 minutes to prevent melting.
Pretzel crunch: Sprinkle pretzels after the drizzle so they adhere but stay crisp.
Clean slices: Chill 10–15 minutes, then cut with a lightly oiled sharp knife or bench scraper.
Make-ahead: Bars keep 2–3 days airtight at room temp; 4–5 days refrigerated (firmer bite).
Freezer-friendly: Freeze up to 3 months—wrap in parchment, then in a zip bag. Thaw at room temp.
Allergy swaps: For school-safe bars, use sunflower seed butter and nut-free toppings. For vegan/dairy-free, use vegan butter, vegan marshmallows, and dairy-free chocolate.
