- 2 1/2 cups all purpose flour
- 2 teaspoons cornstarch
- 1 teaspoon baking soda
- 1/4 teaspoon salt
- 3/4 cup butter
- 1 cup light brown sugar packed
- 1/2 cup sugar
- 1 tablespoon vanilla extract
Optional Topping Ideas
- chocolate candy
- ice cream
- whipped cream
Preheat the oven to 350 F while you whisk the flour, cornstarch, baking soda, and salt in a medium bowl.
Combine the softened butter, brown sugar, and granulated sugar in the bowl of a stand mixer.
While scraping the sides down, add the vanilla and egg, mixing well. Mix the dry mixture to the wet ingredients until well combined. Gently fold the chopped candy into the cookie dough.
Press the dough into the bottom of the cast-iron skillet (12-inch or similar size) and bake for 22 minutes.
Remove the baked cookie skillet from the oven and allow the cookie to cool for 10 minutes. Serve it with a few scoops of vanilla ice cream on top.
Tips & Tricks
- Don’t store leftovers with toppings as this will soften the cookie base.
- Store-bought cookie dough can be added to a stand mixer to combine with the chopped candy.
- A cast iron skillet withstands oven heats and distributes heat evenly. A regular skillet can be used if it’s oven-safe but keep a watch on the cookie. Pie dishes (round or square) offer another alternative.
- Don’t over bake this skillet cookie as you want it to be ooey and gooey.
- You can make the cookie dough ahead of time and bake before serving or bake the cookie base the day before and reheat it for 7-10 minutes at 350F.
