Ingredients:
4 cups all-purpose flour
1 teaspoon baking powder
1/2 teaspoon baking soda
1/2 teaspoon salt
1 cup unsalted butter, softened
1 1/2 cups white sugar
2 large eggs
2 teaspoons vanilla extract
1 cup sour cream
Directions:
Preheat your oven to 350°F (175°C) and line baking sheets with parchment paper.
In a medium bowl, whisk together the flour, baking powder, baking soda, and salt.
In a large bowl, cream together the softened butter and white sugar until light and fluffy.
Beat in the eggs one at a time, then stir in the vanilla extract.
Gradually add the dry ingredients to the wet ingredients, alternating with sour cream, beginning and ending with the dry ingredients. Mix well after each addition.
Drop rounded tablespoons of dough onto the prepared baking sheets.
Bake for 10-12 minutes or until the edges are lightly golden.
Allow the cookies to cool on the baking sheets for a few minutes before transferring them to wire racks to cool completely.
