  • 1/2 cup butter softened
  • 1 1/2 cups granulated sugar
  • 2 large eggs room temperature
  • 1 cup sour cream room temperature
  • 1 teaspoon vanilla extract
  • 2 3/4 cups all purpose flour
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon baking powder

  • Cream together butter and sugar in a large bowl.

  • Cover bowl with saran wrap, place in fridge, and let it chill for an hour.
  • Preheat oven to 350 degrees F and line a baking sheet with a silicone mat.
  • Scoop dough onto a prepared baking sheet using a cookie scoop and bake in preheated oven for 8 - 10 minutes. (Time will depend on cookie size - if using a large cookie scoop, I like 14 minutes)
