Frosted Sugar Cookies
These are soft, cakey sugar cookies with a thick layer of vanilla frosting, similar to the Lofthouse-style cookies found in stores. The dough uses sour cream for a tender crumb and a slight tang that balances the sweetness of the frosting.
Ingredients
For the Sugar Cookies:
- 2 3/4 cups cake flour
- 1/2 tsp baking powder
- 1/2 tsp kosher salt
- 1/2 cup plus 1 tbsp unsalted butter 1 stick, melted
- 1 1/2 cups granulated sugar
- 1 large egg
- 2 1/4 tsp vanilla extract
- 1/2 cup plus 1 tbsp sour cream
For the Vanilla Frosting:
- 1/2 cup plus 1 tbsp unsalted butter 1 stick, softened
- 2 1/4 cups powdered sugar
- 1 tsp vanilla extract
- Pinch kosher salt
- 1-2 tbsp milk as needed
Instructions
- Whisk cake flour, baking powder, and salt in a medium bowl.
- In large bowl, whisk melted butter and sugar until combined. Add egg and vanilla, whisk until smooth.
- Fold flour mixture into wet ingredients in three additions, alternating with sour cream. Mix until just combined.
- Cover and refrigerate dough for 1 hour.
- Preheat oven to 350°F. Line baking sheets with parchment.
- Scoop 2 tablespoon portions of chilled dough onto sheets, spacing 2 inches apart. Flatten tops slightly.
- Bake 12-15 minutes until edges set and centers are matte. Do not brown.
- Cool on sheets 5 minutes, then transfer to wire rack.
- Beat softened butter until creamy. Add powdered sugar, vanilla, and salt. Beat until fluffy, adding milk as needed for spreading consistency.
- Once cookies are completely cool, spread with frosting.
- Add sprinkles immediately if using.
Notes
Dough can be chilled overnight. Frosting will form a light crust as it sets.
