S’mores Cookie Bars Ingredients
Here’s what you need to make these easy cookies.
For the graham cookie base:
- Crushed graham crackers
- Butter, at room temperature
- Granulated sugar and brown sugar
- Large egg
- Vanilla extract
- All-purpose flour, plus baking powder and salt
For the filling:
- Chocolate bars
- Marshmallows (or a jar of marshmallow creme)
I use traditional marshmallows in this recipe. Somehow it just seems… right. But you can easily substitute marshmallow creme if you prefer.
How to Make S’mores Cookie Bars
Begin by preheating the oven to 350°F and lining an 8×8-inch baking pan with parchment.
Step 1: Make the graham cookie dough
Cream together butter and sugar until light and fluffy. Add the egg and vanilla and mix. Then add the dry ingredients: flour, baking powder, salt and crushed graham crackers.
Step 2: Divide the dough and make the layers
Divide the dough in half. Then, press 1/2 of the dough in the bottom of an 8×8 baking pan. Lift out the parchment with the dough on it and set it aside. This is the top layer, then:
- Line the pan with a second sheet of parchment, pressing the remaining dough into the bottom. This will be your bottom layer.
- Top with chocolate bars.
- Finally, top the chocolate with marshmallows. I lay mine on their sides.
- Cover the marshmallows with the top layer of graham dough you set aside.
Step 3: Bake the cookies
Bake for 30 minutes or until golden brown. Cool completely before cutting, as the cookies will be good!
