Ingredients You’ll Need

For the Bars

1/4 cup unsalted butter this gives the bars their soft, rich base.
1 (10 oz) bag mini marshmallows about 5 cups; they melt beautifully and keep everything soft.
1/2 cup peanut butter creamy, cozy, and just the right amount of nuttiness.
6 cups Rice Krispie cereal the classic crunch we all know and love.

For the Chocolate Topping

8 oz chocolate chips semisweet or milk, whichever comfort you prefer.
2 teaspoons vegetable oil for a silky-smooth, glossy finish that slices cleanly.

How to Make It

Grease the Pan

Lightly butter or spray a 9×13-inch pan. This is your soft landing spot for the gooey goodness to come. It also makes slicing the bars later feel dreamy instead of sticky.

Melt the Butter, Marshmallows & Peanut Butter

In a large saucepan over low heat, melt together the butter, mini marshmallows, and peanut butter. Stir gently, watching everything swirl into a golden, velvety cloud. The slower the melt, the softer the treats so don’t rush this cozy moment.

Fold in the Rice Krispies

Remove the pot from the heat and immediately stir in the cereal. The mixture will thicken quickly, turning into that familiar, warm, sticky cluster. Every scoop should glisten with peanut-buttery sweetness.

Press Into the Pan

Spray your hands lightly with cooking spray and press the mixture evenly into the prepared pan. Press softly too much pressure makes the bars dense. Think of it like tucking a blanket, not packing a suitcase.

Melt the Chocolate

Add the chocolate chips to a medium heatproof bowl. Microwave in 45-second intervals on medium power, stirring between each burst. When the chips look mostly melted, keep stirring until the chocolate is perfectly smooth. Stir in the vegetable oil for shine.

Pour & Set

Pour the warm chocolate over the cereal bars and gently spread it to every corner. Let the pan rest at room temperature for about 2 hours, allowing the chocolate to harden into a silky sheet.

Slice & Store

Once set, slice into squares large, small, or somewhere indulgently in between. Store in an airtight container at room temperature for soft, dreamy bites anytime.

Cozy Tips & Serving Ideas
