Peanut Butter S’mores Bars are ooey and gooey, complete with graham crackers, melted chocolate, toasted marshmallows, and crunchy Reese’s pieces. But what really sets these apart is a moist and chewy layer of peanut butter cookies.

My recipe hack is to use refrigerated peanut butter cookie dough — you don’t even have to make it from scratch! Just place the dough into the bottom of a graham cracker-lined cookie sheet, and they’ll bake up perfectly.

You could also use my homemade Peanut Butter Cookies or Double Chocolate Chip Cookies instead of ready-to-bake cookie dough for this recipe.

How To Make Peanut Butter S’mores Bars

1. Arrange the graham cracker squares on a parchment-lined baking sheet. Make sure you break the graham cracker into squares and don’t leave them as whole rectangles.
2. Place one unbaked ready-to-bake cookie on each square and flatten them slightly before baking for 6 minutes.
3. Remove from oven and add the marshmallows, candy, and chocolate chips and bake for an additional 6 to 7 minutes.
4. Remove from oven and pull apart to eat.

Variations Of Peanut Butter S’mores Bar Recipe:

Chocolate Chip Cookies: Use ready-to-bake chocolate chip cookie dough instead of peanut butter cookies if you have a nut allergy or prefer that flavor.

M&M’s: If you’re not a fan of Reese’s pieces, you can use mini chocolate chips, peanut butter chips, or M&Ms instead.

Sugar Cookies: Use ready-to-bake sugar cookies instead of peanut butter and use white chocolate and sprinkles on the top for a fun Birthday Cake-like version!

Caramel: Drizzle with caramel for even more gooeyness!

Nuts: Sprinkle the top of the cookie dough with chopped nuts before adding the marshmallows for added crunch!
