Preheat your oven to 350° and prepare you mini skillet pans by greasing them so your cookies do not stick.
In a large bowl add your browned butter, brown sugar and 1/4 cup of the sugar and mix until combined. Let your brown butter cool down a little bit before adding more ingredients.
Next, add your your egg, egg yolk, pumpkin purée and vanilla and whisk until well combined.
Add your flour, cornstarch, baking soda, 1 tbsp of the cinnamon, your pumpkin pie spice & salt into your mixture. Stir until just combined.
In a small bowl add remaining sugar and cinnamon to make a cinnamon sugar mixture.
Once your dough is ready, add two scoops of cookie dough (about 1/4 cup) into each skillet, sprinkle with your cinnamon sugar and bake at 350° for 8-10 minutes.
Remove from oven and let cool. Add your vanilla ice cream (or ice cream of choice), and sprinkle with some extra cinnamon.
Share and enjoy your delicious fall cookie.
