In a large bowl, whisk 1/2 cup of room temperature butter and 1 cup of granulated sugar until fluffy
Add 1 large egg, 1 teaspoon of vanilla extract and 1/4 teaspoon of almond extract whisk until creamy
Add 1/3 cup of sour cream and mix to combine
Sift 1 cup of cake flour, 1 1/3 cups of all purpose flour, 1 tablespoon of cornstarch, 1/2 teaspoon of baking soda, 1/2 teaspoon of baking powder and 1/4 teaspoon of salt into the bowl and mix until just combined
Use a greased cookie dough scoop to portion the dough onto a parchment lined baking sheet
Chill the dough for 20 minutes in the freezer or 1 hour in the refrigerator
Preheat your oven to 350 degrees
Bake the cookies in a 350 degree over for 8-9 minutes or until the cookies look puffed and no longer appear glossy on the top
Allow the cookies to cool for a few minutes on the baking sheet and then carefully transfer them onto cooling racks to cool fully before frosting
