Instructions
Preheat oven to 350° F.
Using a stand mixer or bowl and hand mixer, beat together the softened butter and dark brown sugar together on medium high for 2-3 minutes, until light and fluffy. Add egg and vanilla and beat until well combined. Scrape down the sides and mix to combine.
Add the flour, salt and baking soda and mix only until combined. Add the chocolate chips and stir by hand with a spatula to combine.
Butter the sides and bottom of a 10 inch cast iron skillet (or 8 inch cake pan). Press the cookie dough into the bottom of the pan. Bake for 17-20 minutes, until the edges are set and the tops has turned matte.
Serve warm with ice cream and toppings! Enjoy!
Notes
Store in an airtight container for up to 3 days.
Beat the butters and sugars until fluffy, then again after adding the egg and vanilla beat until fluffy. This will yield the best possible texture in the end.
Make sure to wait at least 15 minutes before adding ice cream or it melts too quickly! We found 15-25 minutes to be the sweet spot of melty ice cream but not soupy ice cream.
Store in a freezer in an airtight container for up to 2 months.
The dough may also be frozen and stored in the freezer for up to 2 months. Thaw completely in the refrigerator then allow to sit at room temperature for 20 minutes before use.
