I'm turning s'mores into an easy no-campfire treat with these Peanut Butter S'mores Bars. Loaded with graham cereal, chocolate, and plenty of gooey marshmallow, the addition of peanut butter only makes these bars more irresistible.

Ingredients

• Golden Grahams cereal - Replaces traditional crisped rice cereal to give the graham cracker s'more vibe.
• Peanut butter - I like creamy peanut butter because it melts smoothly into the marshmallow mixture. Use crunchy peanut butter to add another layer of texture to the bars.
• Marshmallows - I love folding in extra marshmallows to the cereal mixture for an extra pop of chewiness.
• Chocolate - What's a s'more without chocolate? We're folding chips into the marshmallow mixture and topping the bars with more chocolate.

Step-by-step instructions

See the recipe card for complete instructions and ingredient amounts.

1. Line a 9x13 pan with parchment paper and set aside.
2. Add the cereal to a large zipper-top bag and crush into smaller pieces. Set aside.

3. In a large, heavy-bottomed pot set over medium-low heat, add the butter and peanut butter. Stir until melted.
4. Add the marshmallows and stir until fully melted and smooth.

5. Add the crushed cereal and stir to combine. Add the chocolate chips and extra marshmallows. Fold together. NOTE: Don't worry if the chocolate chips start melting into the warm mixture. S'mores are all about melty gooey ingredients.
6. Quickly transfer the mixture to the prepared pan. Press into an even layer.

7. Using a double-boiler or the microwave, melt the chocolate, stirring until completely smooth.

• Double-boiler: Place a glass bowl over a saucepan of simmering water. Be sure the bottom of the bowl does not touch the water. Add the chopped chocolate and stir until completely melted.
• Microwave: Add the chopped chocolate to a glass bowl. Heat on high for 20-30 second intervals, stirring after each, until the chocolate is completely melted and smooth.

8. Pour the melted chocolate over the marshmallow bars and spread evenly. Top with extra crushed cereal.

9. Allow the bars to set up at room temperature.
10. Slice and serve. PRO TIP: Use this 5 wheel pastry cutter for perfectly even squares every time. This is my favorite tool for cutting bars, brownies, fudge, and more!

Tips for making cereal bars

• Line the pan with parchment paper so you can remove the bars from the pan for ease of cutting and serving. Spray the pan with cooking spray first to help hold the parchment in place when spreading the sticky mixture.
• Use a silicone spatula or spoon to mix the sticky marshmallow mixture. You can also spray the spatula with cooking spray to further prevent the mixture from sticking.
• Spray your fingers with cooking spray before pressing the mixture into the pan.
• Store the bars in an airtight container at room temperature.
