A big soft pumpkin snickerdoodle cookie baked in a skillet. Filled with pumpkin, brown sugar, and pumpkin pie spice, you'll love the warm and comforting flavors in this easy fall dessert.
Preheat oven to 350°F. Grease a 10-inch cast iron skillet. If you'd prefer to make a smaller size you can use a 8-inch cast iron skillet (four servings); see note for ingredient amounts for the smaller cookie.
In a large bowl, combine flour, cream of tartar, baking soda, salt, pie spice, and cinnamon. Set aside.
Using a hand mixer or stand mixer, beat butter and both sugars until creamy and combined (a minute or two). Add pumpkin puree (see note about drying), eggs, and vanilla, and beat to combine, scraping the sides and bottom of the bowl as needed. Add the dry ingredients, beating until combined. Stir in white chocolate chips, if using. Scoop the batter into the prepared skillet, smoothing the top with a rubber spatula or moistening your fingers with water and pressing it in.
In a small bowl combine sugar and cinnamon (for the topping). Sprinkle evenly over the top of the dough. Bake for 20-25 minutes, until the edges are golden brown and the center no longer jiggles. Check the center with a toothpick, moist crumbs are ok, just no raw batter. Allow to cool slightly, serve warm with ice cream and caramel sauce.
Notes
Blotting pumpkin:
For the best results, it is important to remove excess moisture from the pumpkin puree. Place a double layer of paper towels on a plate. Spread the pumpkin puree onto the towels. Place a double layer of paper towels on top of the pumpkin and lightly press down allowing the paper towels to soak up excess moisture. Repeat this step one more time with fresh dry paper towels.
