Preheat oven to 350°F and prepare cookie sheets with Parchment paper.
Place the Butter and brown sugars in the bowl of a stand mixer.
Using a stand mixer fitted with the paddle attachment, mix the softened butter and sugar together on medium speed (speed 4for a Kitchen Aid) for 2-4 minutes until light and fluffy.
Next, scrape down the sides of the bowl and add one egg at a time; mixing until fully combined and scraping down the sides of the bowl after each egg.
In a separate bowl, measure the flour, salt, corn starch, and baking powder.
Add the dry ingredients to the mixing bowl and mix on a low speed until the flour is just completely mixed in. Don’t overmix!
Using a cookie scoop, scoop the cookie dough and roll the cookies between the palm of your hands to make a smooth cookie dough ball.
Place the cookies onto the parchment lined cookie sheets (about an inch from each other). Place in the freezer for 5-10 minutes.
In a small bowl, measure out the granulated sugar.
After pulling the chilled cookie dough balls from the freezer and before baking, roll the cookies in the granulated sugar.
Place the tray of cookies in the oven and bake for 12-15 minutes or until the edges are just starting to get golden brown.
Let the cookies cool completely before frosting. Cook The bacon while cookies are cooling.
