Preheat oven to 350°F.
In a large saucepan, melt butter over medium heat until golden and bubbly.
Remove from heat and add vanilla extract, maple syrup, cinnamon, and nutmeg. Stir to combine.
In a large bowl, combine 2/3 cup finely ground sugar cones (about 6 blended), AP flour, baking soda, and salt.
Add brown sugar and white sugar to melted brown butter mixture.
Add your egg and mix until combined. Then, add your dry ingredients, shards of 5 crushed sugar cones, and chocolate.
Scoop cookie dough into 7 even balls with a large ice cream scoop. Bake one immediately to test, and to taste.
Refrigerate the other 6 cookie balls, covered, until ready to bake, up to 24 hours. Remove from fridge and let come to room temperature before baking.
Top your dough balls with large shards of the last sugar cone and chocolate chips. Then, bake for 10-12 minutes until flat and gooey.
Press down on your cookies before baking to ensure they spread, or drop your baking pan on the counter a few times when the cookies come out to help them flatten.
