Chewy Peanut Butter Bars

These peanut butter bars are all about layered texture, three distinct levels that hit chewy, gooey, and crunchy in a single bite.

It starts with a soft cookie base, pressed into the pan and baked just until golden. While it’s still warm, a scatter of mini marshmallows goes on and back into the oven for a couple of minutes, just until they puff and turn pillowy. Watch them closely, because they go from puffed to scorched fast.

The crowning layer is where the crunch lives: peanut butter chips melted with corn syrup and butter into a glossy, sticky topping, then loaded with crisp rice cereal and salted peanuts. Spread warm over the marshmallows, it sets into a chewy-crunchy peanut layer.

A spell in the fridge firms everything up so the bars slice cleanly into neat squares, with all three layers holding together.

Pro Tips

• Watch the marshmallows closely during their short bake; they puff and then burn in moments.
• Spread the topping while it’s still warm and pourable so it covers evenly before it sets.
• Chill the bars until fully set before cutting for clean, layered squares.
• The salted peanuts balance all that sweetness, so don’t skip them.

Variations

• Swap the peanut butter chips for butterscotch or chocolate chips.
• Use a mix of peanuts and chopped pretzels for extra salty crunch.
• Drizzle melted chocolate over the top before chilling.
