Sourdough Chocolate Chip Cookie Skillet

2 Preheat your oven to 350F degrees.
0 Melt the butter in a small pot or microwave. Set aside and let cool.
1 In a medium mixing bowl, add in the cooled butter and brown sugar. Mix with a whisk until combined.
3 Next, add in the egg, sourdough discard, and vanilla extract. Mix.
4 Pour in the flour, baking powder, and sea salt. Mix until incorporated with a rubber spatula.
5 Sprinkle in the chocolate chips and fold to combine. 
6 Add the dough to a greased 6in cast iron skillet or a similar sized pan. Bake in the oven for 25-30 minutes. Bake less for a doughy spoonable skillet and bake longer for a more set skillet that you can cut into slices once cooled.
7 When it's done, sprinkle with flakey sea salt. Optional: top with vanilla ice cream and dive in. Enjoy!
