Why You Must Make

They have the 3 components of the classic campfire treat: Graham Crackers, Chocolate, and Marshmallow!
The fluffy marshmallow meringue topping is homemade and SO much better than any marshmallow you’d ever get out of a bag!
These are fun for summer gatherings when it’s too hot to light a fire to make old-fashioned s’mores.

Ingredient Notes:

Graham Cracker Crumbs – Buy by the box or grind your own in a food processor using graham crackers.
Milk Chocolate Chips – May use semisweet chocolate chips if desired.
Cream of Tarter – Stabilizes the meringue topping.
Egg Whites – Make sure whites, bowl, and beaters are free from any grease, oil, or egg yolk or the egg whites won’t whip correctly.
Corn Syrup – I use Karo brand. Spray your measuring cup with Pam to help it slide out easily.

Expert Tips:

The marshmallow topping is made with egg whites. PRO-Tip: When you whip egg whites, your utensils must be scrupulously clean or the meringue will not get white and fluffy. Make sure your bowl and beaters do not have any traces of oils and if even one speck of egg yolk contaminates the whites, they will not whip properly.
PRO-Tip: Use a hot dry knife to cut these bars. The topping is sticky and the heat will help the knife “melt” its way through.
Reheat your knife once it starts sticking again. I run it under my hot water dispenser, then wipe it dry with a towel.
You can purchase graham cracker crumbs, but you can also make them at home by breaking up graham cracker squares and running them through the food processor. The latter is more economical, too!

This s’mores bars recipe has a gooey topping so it’s best to keep them in a single layer, in a covered container in the refrigerator for 3-4 days. Keep s’mores bars made with bagged marshmallows covered at room temperature or in the refrigerator.
