Preparation
- Line a 9x13-inch baking pan with parchment paper or lightly grease it with nonstick spray.
Make the Peanut Butter Dough Base
- In a large bowl, combine all-purpose flour and confectioners’ sugar. Add creamy peanut butter and softened unsalted butter. Mix until smooth and even.
Prepare the Marshmallow Mixture
- In a medium saucepan over low heat, melt unsalted butter. Add marshmallows and light-colored corn syrup. Stir continuously until melted and smooth. Remove from heat and stir in vanilla extract.
Combine Crispy and Nutty Ingredients
- Add Rice Krispies cereal and salted peanuts to the melted marshmallow mixture. Stir gently to coat evenly without crushing.
Assemble the Layers
- Press the peanut butter dough evenly into the bottom of the prepared baking pan. Pour the marshmallow, cereal, and peanut mixture over the base and spread evenly.
Add Peanut Butter Chips and Chill
- Sprinkle peanut butter chips evenly over the top. Let the heat soften the chips for a couple of minutes, then gently swirl some melted chips into the top layer for a marbled effect.
- Place the pan in the refrigerator for about 2 hours or until fully set. Once firm, lift out using parchment paper and cut into squares or bars. Serve chilled or at room temperature.
Notes
- Press the peanut butter dough firmly for a solid base that won’t crumble.
- Use large marshmallows for thicker bars and mini marshmallows for thinner, less gooey bars.
- Store bars in an airtight container at room temperature for up to 3 days or refrigerate for up to a week.
- Freeze individual bars wrapped tightly for up to 3 months; thaw before serving.
- Customize by using gluten-free flour, natural peanut butter, or vegan substitutes for dietary preferences.
