Preheat your oven to 375 degrees. Line two baking sheets with parchment and set aside.

Whisk together the flour, baking soda, and salt in a small bowl. Set aside.

Cream the butter, shortening, and sugar until light. Stir in the egg, extract, sour cream, and dry ingredients.

Turn the dough onto a lightly floured surface and roll 1/4 inch thick. Cut using your desired shape. Place on the baking tray and cook for ten minutes or until the edges are just lightly browning.

Cool completely. Top with cream cheese frosting and fresh berries.
