Made with simple pantry ingredients, these whipped shortbread cookies are incredibly soft and tender. Decorate them with sprinkles for a great holiday cookie.
In a large bowl, or a stand mixer fitted with the paddle attachment, beat the butter and sugar on medium-high for 4-5 minutes until light and fluffy. Mix in the vanilla extract.
In a medium bowl, whisk together the flour and cornstarch.
Gradually beat in the flour mixture on low speed until JUST combined.
Roll the dough into smooth 1-tablespoon balls. Place 1-2 inches apart on parchment-lined baking sheets. Use a fork to gently, slightly flatten each cookie. Add sprinkles, if desired.
Chill the dough balls in the fridge for at least 1 hour (this prevents the cookies from spreading when baking). You can speed this up by putting them in the freezer.
Preheat your oven to 325°F. Bake for 12-14 minutes until the edges are lightly golden. Cool completely on the baking sheets.
