Cast-iron Skillet Cookie

An invisible internet friend shared this recipe on Facebook.  I am cutting and pasting here so I can try it tomorrow.  I may or may not share it with my family.

1cup (2 sticks) butter softened
1/2 cup brown sugar
1/2 cup white sugar
3/4 cup flour
2 eggs
2 tsp baking soda
1 tsp salt
1/4 cup peanut butter
1 cup rolled oats
1/4 cup chocolate chips
Preheat oven to 350
Cream butter and sugars together
Add peanut butter and eggs mix well. 
Add flour, salt, baking soda.
Fold in oats and choc chips. 
Lightly grease a medium-sized cast iron skillet and fill with cookie dough smoothing it out without packing it too much. 
Bake until edges are golden brown and center is still moist.
For drizzle: 
Mix 2 tablespoons chocolate chips with 2 tsp coconut oil and microwave just until melted. Stir and drizzle on top of cookie. Let cool slightly and serve!
