These Sour Cream Cookies have a luxurious, tender, and buttery texture. Butter and sour cream combined result in a dreamy, creamy texture with the perfect crispy and golden edges. Top them with buttercream frosting and sprinkles for the prettiest simple cookies that are so much fun to make with kids!
Preheat your oven to 350°F and line a baking sheet with parchment paper.
In a large mixing bowl, (or the bowl of a stand mixer) blend together the softened butter and sugar until the mixture is light and fluffy with an electric hand mixer (or the paddle attachment).
Add the egg and mix to ensure it's well combined.
Add the sour cream and vanilla extract, mixing thoroughly.
In a separate bowl, whisk together the flour, baking powder, baking soda, and salt.
Gradually incorporate these dry ingredients into the wet mixture, stirring just until combined.
Using rounded tablespoons or a small cookie scoop, drop portions of the cookie dough onto the prepared baking sheet, leaving 2 inches of space between each cookie.
Bake for 10-12 minutes or until the edges are lightly golden brown.
Allow the cookies to cool on the baking sheet for 5 minutes before transferring them to a wire rack to fully cool.
After a 30-minute cooling period, generously spread buttercream on the cookies and embellish with sprinkles.
Notes
Do not overmix the cookie dough or you will lose the beautiful light cakey cookie texture and have a tough cookie instead.
For the best flavor, store leftover cookies in an airtight container in the refrigerator for up to 3 days.
Try lemon zest or almond extract as an alternative to vanilla extract. You can also add a spiced buttercream for fall.
Do not overbake the cookies; they should just be slightly golden on the edges.
