how to make S’mores cookie bars

Ingredients

  • 1/2 cup Butter (softened, salted or unsalted)
  • 1/3 cup brown sugar
  • 1/4 cup granulated sugar
  • 1 egg
  • 1 tsp vanilla extract
  • 1 & 1/2 cup all-purpose flour
  • 1/2 cup graham crackers (finely crushed, about 3.5 sheets, for the cookie dough)
  • 1/4 tsp salt
  • 3/4 tsp baking soda
  • 5 standard Hershey bars
  • 1 & 1/2 cup Marshmallow fluff

Directions

  1. Preheat the oven to 350°F. Line an 8×8 inch baking pan with parchment paper and set it aside.
  2. Cream the softened butter, granulated sugar, and brown sugar together until well combined.
  3. Add in the egg and the vanilla extract, mixing until combined.
  4. Slowly stir in the flour, graham cracker crumbs, salt, and baking soda. Mix just until the flour disappears.
  5. Press half of the dough evenly onto the prepared baking sheet. Remove that layer from the pan and place it in the freezer while you re-line the pan with more parchment paper.
  6. Repeat the process with the remaining cookie dough.
  7. Break the chocolate bars into pieces and lay them over the dough, fitting them to cover the whole surface.
  8. Spread marshmallow fluff or cream on top of the chocolate layer.
  9. Gently flip the chilled cookie dough layer on top, being careful to keep it intact.
  10. Bake in the preheated oven for 25 minutes.
  11. Let the bars cool completely before slicing into them to reveal that beautiful cross-section.

how to serve S’mores cookie bars

S’mores cookie bars are best served fresh and warm, but they can also be enjoyed at room temperature. You can cut them into squares or rectangles for easy sharing. Consider serving them with a scoop of vanilla ice cream or drizzling some chocolate sauce on top for an extra touch.

how to store S’mores cookie bars

Store the S’mores cookie bars in an airtight container. They can be kept at room temperature for up to three days. If you want them to stay fresh longer, you can refrigerate them for a week. You can also freeze the bars in a freezer-safe container for up to three months.

tips to make S’mores cookie bars

  • Ensure the butter is softened for easier mixing and creaminess in the bars.
  • If you prefer a thicker bar, you can use a smaller baking pan to increase the height.
  • Keep a close eye on the baking time; oven times may vary, and you want them to be golden brown without over-baking.

variation

You can add nuts, like chopped walnuts or pecans, to the cookie dough for added crunch. For a twist, consider using different types of chocolate, such as caramel-filled or mint chocolate bars. If you enjoy peanut butter, you can layer some peanut butter on top of the chocolate before adding the marshmallow fluff.

FAQs

Can I use graham cracker crumbs instead of crushing the crackers?

Yes, pre-packaged graham cracker crumbs will work perfectly! Just ensure you measure them correctly.

What if I don’t have marshmallow fluff?

You can use mini marshmallows instead. Just layer them on top of the chocolate, and they will melt as they bake.

How do I know when my bars are done?

The edges should be slightly golden, and the center may look a little soft. They will firm up as they cool.
