Ingredients
Cookies
- 1½ cups all-purpose flour (188 grams)
- 2 teaspoons cornstarch
- ½ teaspoon baking powder
- ¼ teaspoon baking soda
- ¼ teaspoon salt
- ½ cup unsalted butter (112 grams), softened but not melting
- ¾ cup granulated sugar (150 grams)
- ½ cup full-fat sour cream (120 ml), room temperature
- 1 large egg, room temperature
- 1½ teaspoons vanilla extract
- ¼-½ teaspoon almond extract
Frosting
- ¾ cup unsalted butter (168 grams), softened
- ¼ cup vegetable shortening (or substitute with an additional ¼ cup butter)
- 3-4 cups powdered sugar (sifted) (33-440 grams)
- 1 teaspoon vanilla extract
- ¼ teaspoon salt
- 3-4 tablespoons whipping cream (45-60 ml) or milk
- ½ cup nonpareil sprinkles (100s and 1000s)
Instructions
- Prepare Dry Ingredients: In a large bowl, whisk together the all-purpose flour, cornstarch, baking powder, baking soda, and salt until well combined. Set aside for later use.
- Cream Butter and Sugar: In a separate large bowl, use a mixer to beat the softened butter and granulated sugar together until light and fluffy, about 2-3 minutes.
- Add Wet Ingredients: Beat in the egg, sour cream, vanilla extract, and almond extract into the creamed butter mixture. Occasionally stop the mixer to scrape down the bowl sides to ensure even mixing.
- Combine Dry and Wet Ingredients: On low speed, gradually mix the dry ingredients into the wet mixture. Continue mixing until no lumps remain and a thick dough forms.
- Chill Dough: Cover the dough bowl and refrigerate for at least 1 hour, or up to 48 hours, to help firm up the dough for easier handling and better texture.
- Preheat Oven and Prepare Baking Sheets: When ready, preheat the oven to 350°F (180°C). Line two cookie sheets with parchment paper or silicone baking mats.
- Scoop Cookies: Use a cookie scoop or spoon to portion about 1½ tablespoons of dough per cookie. Place dough balls on prepared sheets, spacing them about 2½ inches apart for spreading.
- Bake Cookies: Bake one sheet at a time in the oven’s middle rack for 12-14 minutes. The cookies should look set on top and spring back slightly when lightly pressed.
- Cool Cookies: Allow cookies to cool completely on the baking sheets to firm up.
- Make Frosting: In a large bowl, beat the softened butter until smooth. Add the vegetable shortening and continue beating.
- Add Sugar and Flavoring: Incorporate 3 cups of powdered sugar, vanilla extract, and salt. Start mixing on low speed, then increase to medium until well combined.
- Adjust Frosting Consistency: Beat in whipping cream one tablespoon at a time, alternating with more powdered sugar if needed, until the frosting is smooth, sweet, and pipeable.
- Prepare for Decorating: Ensure cookies are completely cooled. Line a cookie sheet with clean parchment or wax paper. Transfer frosting to a piping bag fitted with a large round tip or a plastic freezer bag with the tip cut off.
- Pipe Frosting: Apply a large round dollop of frosting on top of each cookie.
- Freeze for Firmness: Turn the frosted cookies upside down onto the lined tray to flatten frosting slightly. Freeze for about 20 minutes until frosting firms.
- Add Sprinkles: Pour sprinkles onto a plate. Remove cookies from freezer and carefully peel from parchment. Dip the frosted side into the sprinkles, gently pressing to adhere.
- Alternative Decorating: Optionally, frost cookies with a flat knife and then dip into sprinkles for a different texture.
Notes
- The dough can be refrigerated for up to 48 hours to improve flavor and texture.
- Make sure all wet ingredients like egg and sour cream are at room temperature to ensure smooth batter.
- Chilling the frosting before dipping helps keep the sprinkle coating intact.
- If you prefer a less sweet frosting, reduce powdered sugar or increase whipping cream accordingly.
- Use parchment paper fresh for decorating to prevent sticking during sprinkle application.
- Store finished cookies in an airtight container at room temperature for up to 3 days.
- For dairy-free, substitute butter and sour cream with suitable plant-based alternatives.
