Looking for more cookie bar recipes? Try our Oatmeal Cookie Bars, Sugar Cookie Bars, Peanut Butter Bars or M&M Cookie Bars! I can’t resist the combination of marshmallows, chocolate and graham crackers and these S’more Bars are easy to make, any time of year. They’re always a huge crowd favorite, and I love that you can make them a day ahead, or even freeze them, with wonderful results.
How to Make S’mores Bars:
Make graham cracker cookie dough: Combine flour, graham cracker crumbs, baking powder and salt. In a separate large bowl, cream the butter and sugar together until light and fluffy, about 2 minutes. Add the eggs and vanilla and beat until well combined. Reduce the mixer speed to low and add the flour mixture, mixing until combined. Press half the cookie dough evenly into the bottom of a 9×13 pan lined with parchment paper. Add marshmallow fluff on top of the cookie dough. (Tip: If the creme gets sticky, dip your spoon in hot water, to help it spread smoothly.) Add chocolate pieces on top of the marshmallow creme. Top with remaining cookie dough. Break off small pieces and place the dough all over the top, flattening into an even layer as best you can. Bake at 350F for 28-32 minutes. Cool completely before cutting.
Freezing Instructions:
Place parchment paper in pan before baking. Allow baked bars to cool completely, then lift the cooled bars out of the pan by pulling up on the parchment paper. Wrap the bars in plastic wrap and aluminum foil. Freeze for up to 3 months. Thaw completely before serving. *I first shared this post in July 2014. Updated June 2018, June 2021 and May 2022.
