S’Mores Chocolate Chip Cookie Bars are one of the sweet treats perfect for a crowd or parties! Easy delicious dessert with graham crackers, chocolate chips and homemade marshmallow cream.
S’Mores Chocolate Chip Cookie Bars are easy to make, and it is so delicious! You practically need 6 ingredients, of which you, most likely, have 4 at any time in your kitchen (butter, sugar, 2 eggs, all-purpose flour). For the same reason, I found it easier to make my, homemade marshmallow cream than using a storebought.
How Do You Make Homemade Marshmallow Cream?
For 3 cups of marshmallow cream, you will need just one egg white, sugar and water (optionally, +vanilla extract), and 10-15 minutes of your time. Egg (or eggs, if you want to double de recipe) should be at room temperature, took out from the fridge one hour before making the recipe. Or, if you are in hurry, place eggs in a bowl of warm water (not hot!) for 5-10 minutes.
Start with making sugar syrup. In a medium saucepan, add the sugar and water and cook over medium heat, stirring constantly until syrup is translucent and without granules of sugar (about 5 minutes). Remove from heat, (stir in the vanilla extract) and set aside.
Beat egg white with a mixer (using a whipping attachment) on low speed until foamy. Increase the speed to medium and continue to beat until the white stays firm (soft peaks).
Slowly add the syrup, 1-2 tablespoons at a time, mixing constantly. Increase the speed to medium-high and beat for 5 minutes more.
Store in the fridge until use. The marshmallow cream will separate after a few hours of refrigeration, so it will be best if you use it soon after you made it.
