Step 1

In a stand mixer using the paddle attachment, or in a medium bowl using a hand-mixer, beat together the butter and sugars (both dark + granulated) for about 3 minutes until well combined and pale in color.

Step 2

To the bowl, add the egg, egg yolk, and vanilla extract. Beat to combine for about 1 minute.

Step 3

In a separate bowl, combine the dry ingredients - flour, baking soda, salt, cinnamon. Gently mix together.

Step 4

In increments of three, add the dry ingredients into the wet until combined and a dough forms.

Step 5

Grab a parchment lined baking sheet and roll the dough into 2 tbsp size balls. Roll through the additional 1/4 cup sugar + 1 tsp cinnamon, and place on the baking tray. They can be touching here. Put in the fridge for at least an hour, up to overnight.

Step 6

When ready to bake, take your cookies out of the fridge and allow them to come down closer to room temp while you preheat your oven to 350℉. Bake the cookies on a parchment lined baking sheet for 14-16 minutes. Allow them to cool on the baking sheet.

Step 7

Enjoy!
