This pretty little guy has a peanut butter cookie base and is topped with a layer of chocolate and a layer of perfectly toasted marshmallows. Need I say more? It’s heaven in a skillet.

Peanut Butter S’mores Skillet Cookie

1. In the bowl of a stand mixer (I used this one) cream the butter, peanut butter, and both sugars until creamy and smooth. Add eggs one at a time, mixing fully after each addition.
2. In a separate bowl, combine the flour, baking powder, baking soda, and salt. Whisk to combine.
3. Add dry ingredients to the butter mixture and mix until just combined.
4. Chill the dough for at least 30 minutes.
5. Preheat the oven to 375 degrees (F).
6. Spray a 6.5-inch dish (I used a cast-iron dish like this, but you can use any type) with non-stick spray and press the cookie dough into the pan.
7. Bake for 20-25 minutes or until the outside of the cookie is golden brown and the center isn’t too soft.
8. Remove the cookie from the oven and cover it with the chocolate chips. If you are using mini marshmallows you cover the top of the cookie with them now. If you are using regular marshmallows, like I did, cut them in half and arrange them on top of the chocolate.
9. Turn your oven to broil and place the cookie back in the oven until the marshmallows are toasted to your liking.
10. Remove from oven and allow to cool slightly before digging in!
