Creating Russian Sour Cream Cookies is simple if you follow these easy steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C). Line a baking sheet with parchment paper or a silicone mat.
2. Mix Wet Ingredients: In a large mixing bowl, cream together the softened butter and granulated sugar until light and fluffy.
3. Add Egg and Flavorings: Incorporate the egg and vanilla extract into the butter-sugar mixture, mixing until well combined.
4. Combine Sour Cream: Gently mix in the sour cream until fully integrated.
5. Add Dry Ingredients: In a separate bowl, whisk together the flour, baking soda, baking powder, and salt. Gradually add this mixture to the wet ingredients, mixing gently until a dough forms.
6. Scoop the Cookies: Using a cookie scoop or tablespoon, drop rounded balls of dough onto the prepared baking sheet, allowing some space between each cookie.
7. Bake: Place the baking sheet in the preheated oven and bake for 15-20 minutes, or until the edges are lightly golden.
8. Cool: Remove the cookies from the oven and let them cool on the baking sheet for a few minutes before transferring them to a wire rack to cool completely.
9. Dust with Powdered Sugar: Once the cookies have cooled, feel free to dust them with powdered sugar for an elegant finish, if desired.

With these simple steps, you’ll have a batch of soft and delectable Russian Sour Cream Cookies ready to be enjoyed!
