Smores Skillet Cookie in 40 Minutes

Instructions:

1. In a large bowl, beat the softened butter, brown sugar, and white sugar until the mixture is pale and fluffy.
2. Add eggs one at a time, beating well after each addition, then stir in the vanilla extract.
3. In a separate bowl, whisk together the flour, graham cracker crumbs, baking soda, and salt.
4. Gradually add the dry ingredients to the wet mixture. Mix on low speed until just combined; do not overmix.
5. Fold in the semi-sweet chocolate chips by hand using a rubber spatula.
6. Grease a 10 or 12-inch cast-iron skillet or line it with parchment paper.
7. Press approximately two-thirds of the cookie dough evenly across the bottom of the skillet.
8. Scatter the broken graham cracker squares and half of the marshmallows over the dough base.
9. Dollop the remaining cookie dough over the marshmallow and graham layer, sealing the core.
10. Top with the remaining marshmallows and bake in the oven for 25 minutes until the edges are caramelized and the center is set.
