How To Make S'mores Bars
1. Preheat and prep: Preheat your oven to 350 °F and grease the baking pan.
2. Crush crackers: Place graham crackers in a zip bag and crush with a rolling pin into coarse crumbs. The easiest (and most fun) way I have found to do this is to let your child crush the crackers using a zipped bag and a rolling pin. Simply insert the crackers, seal the bag, and roll over it with the rolling pin until crumbs are formed.

3. Mix crust: In a bowl, stir cracker crumbs with melted butter and brown sugar. Set aside about ¼ of the mixture for the topping.
4. Bake base: Press the remaining crumb mix into an 8x8 or 9x9 pan and bake for 10 minutes.

5. Add chocolate: What are s'mores without chocolate? Break up pieces of your chocolate bar and add to the baked crust. Placing the pieces of chocolate on the just baked crust needs to be an adult job since the pan will still be warm from the oven.

6. Melt and spread: Return to oven for 5 minutes, then spread the chocolate gently with a spatula.

7. Top with marshmallows: Arrange marshmallows over the chocolate layer and bake 6 minutes (or until they become puffy). I bought some square marshmallows that worked perfectly on these s'mores bars, but traditional or mini marshmallows will work as well.

8. Add crumb topping: Sprinkle the reserved crumb mix over the marshmallows and bake for a final 6 minutes.

9. Chill: Let this cool in the pan, and then refrigerate it for 30 minutes before slicing so it can firm up a bit.

Even after cooling off a bit, the gooey goodness you have come to expect from s'mores remains.

Tips For S'mores Bars
Tip 1: If you want a little extra crunch in the crust, leave some of the crackers in bigger chunks when crushing them.
Tip 2: Remove bars from the fridge before slicing so they don't crumble.
Tip 3: For extra gooey marshmallow tops, broil for 30-60 seconds at the end. Just be sure to watch them closely.

Did you melt the butter to mix in or use softened butter?

These S'mores bars look so very delicious! They'll be perfect for after school snacks for my kiddos. Messy recipes always tend to taste a little better! Huggies are definitely a lifesaver with children, we'd be lost without them.

Looks like a messy (but fun!) recipe! I love s'mores so I am sure I would love these s'more bars. Marshmallow and chocolate are the best combination! And thanks for the tip to have some wipes on hand, because that is easier than getting the whole kitchen sticky!
