Ingredients
For the cookie dough:
1 cup (2 sticks) unsalted butter, softened
1 cup brown sugar, packed
½ cup granulated sugar
2 large eggs
2 tsp vanilla extract
2 ½ cups all-purpose flour
1 tsp baking soda
½ tsp baking powder
½ tsp salt
1 cup graham cracker crumbs (about 8 full sheets, finely crushed)
1 cup semi-sweet or milk chocolate chips
For the filling:
Large marshmallows, cut in half
Hershey’s chocolate bar squares (or any milk chocolate squares)
Instructions
- Preheat oven to 350°F (175°C). Line baking sheets with parchment paper.
- Make the dough:
Cream together butter, brown sugar, and white sugar until light and fluffy.
Beat in eggs one at a time, then add vanilla.
In a separate bowl, whisk together flour, baking soda, baking powder, salt, and graham cracker crumbs.
Gradually mix dry ingredients into wet.
Stir in chocolate chips.
- Assemble the cookies:
Scoop about 2 tablespoons of dough and flatten it slightly in your hand.
Place half a marshmallow and a piece of chocolate bar in the center.
Take another tablespoon of dough, flatten, and cover the filling. Seal edges well so the marshmallow doesn’t leak too much.
- Bake:
Place on prepared cookie sheet, spaced about 2 inches apart.
Bake 9–12 minutes, until edges are golden but centers still look soft.
Let cool on the pan for 5 minutes before moving to a wire rack.
- Optional: For extra gooeyness, press an extra piece of chocolate on top while cookies are still warm.
