Why You'll Love This Recipe
About the Ingredients
2 3/4 cups (350g) all-purpose flour
Provides structure. For a lighter texture, you can substitute 1/2 cup with cake flour, but don't use all cake flour.
1/2 teaspoon baking powder
Helps the cookies rise slightly. Make sure it's fresh for best results.
1/2 teaspoon baking soda
Balances acidity and aids in spreading. If you don't have baking soda, you can omit it, but cookies will be less fluffy.
1/2 teaspoon salt
Enhances flavor. Use fine sea salt for even distribution.
1 cup (2 sticks, 226g) unsalted butter, softened
Adds richness and tenderness. If using salted butter, reduce added salt to 1/4 teaspoon.
1 1/2 cups (300g) granulated sugar
Sweetens and helps with browning. You can reduce to 1 1/4 cups if you prefer less sweet.
2 large eggs, room temperature
Bind ingredients and add moisture. Bring to room temperature for better incorporation.
2 teaspoons vanilla extract
Adds flavor. Use pure vanilla extract for best taste; imitation works too.
1/2 cup (120g) sour cream, room temperature
Adds moisture and tenderness. Greek yogurt can be substituted.
Tips & Tricks
- Do not overmix the dough after adding flour, as this develops gluten and makes cookies tough.
- Chill the dough for at least 1 hour to prevent excessive spreading and enhance flavor.
- Use a cookie scoop for uniform cookies that bake evenly.
- Check cookies at the minimum baking time; they should look set around edges but soft in center.
Pro Tips
Step-by-Step Instructions
1. Gather Ingredients and Tools
Measure all ingredients. You'll need mixing bowls, an electric mixer, a whisk, a spatula, baking sheets, and parchment paper. Preheat oven to 350°F (175°C) later.
2. Whisk Dry Ingredients
In a medium bowl, whisk together flour, baking powder, baking soda, and salt. Set aside. This ensures even distribution of leaveners.
3. Cream Butter and Sugar
In a large bowl, beat softened butter and granulated sugar on medium speed until light and fluffy, about 2-3 minutes. Scrape down the bowl. This incorporates air for fluffiness.
4. Add Eggs and Vanilla
Add eggs one at a time, beating well after each addition. Mix in vanilla extract. Ensure eggs are room temperature to avoid curdling.
5. Mix in Sour Cream
Add sour cream and mix until combined. The mixture may look slightly curdled; that's okay. It adds moisture.
6. Incorporate Dry Ingredients
Gradually add dry ingredients to wet mixture, mixing on low speed until just combined. Do not overmix. The dough will be soft.
7. Chill the Dough
Cover the dough and refrigerate for at least 1 hour, or up to 3 days. Chilling prevents spreading and improves flavor.
8. Scoop and Bake
Preheat oven to 350°F (175°C). Line baking sheets with parchment. Scoop dough into 1.5-tablespoon balls and place 2 inches apart. Bake for 10-12 minutes until edges are set and lightly golden, but centers are soft. Do not overbake.
9. Cool and Decorate
Let cookies cool on the baking sheet for 5 minutes, then transfer to a wire rack to cool completely. Decorate as desired or enjoy plain.
Delicious Variations
Lemon Sugar Cookies
Add 1 tablespoon lemon zest and substitute vanilla with lemon extract.
Chocolate Chip Sugar Cookies
Fold in 1 cup of mini chocolate chips before chilling.
Spiced Sugar Cookies
Add 1 teaspoon cinnamon and 1/4 teaspoon nutmeg to the dry ingredients.

Frequently Asked Questions
Q: Why are my sugar cookies flat?
Flat cookies usually result from dough that is too warm or too little flour. Ensure you chill the dough for at least 1 hour and measure flour correctly by spooning and leveling.
Q: Can I use self-rising flour?
Yes, you can substitute self-rising flour for all-purpose flour, but omit the baking powder, baking soda, and salt from the recipe.
Q: How do I keep sugar cookies soft?
Store them with a slice of bread in an airtight container, which releases moisture and keeps cookies soft. Also, avoid overbaking.

Absolutely! Shape the dough into balls, freeze on a baking sheet, then transfer to a zip-top bag. Bake directly from frozen, adding a couple of minutes.
