Sugar Cookie Frosting That Hardens
This sugar cookie frosting is smooth, buttery, and sets perfectly without royal icing. Made with powdered sugar, melted butter, and milk, it creates a glossy bakery-style finish in just 5 minutes.
Equipment
- Mixing bowl
- Fine mesh sieve
- Whisk
- Spatula
Ingredients
- 2 cups powdered sugar, sifted
- 2 tbsp butter, melted
- 2-3 tbsp whole milk
- 1/2 teaspoon vanilla extract (optional)
- Gel food coloring (optional)
Instructions
- Sift the powdered sugar into a medium mixing bowl to remove lumps.
- Add the melted butter and whisk until combined.
- Add milk one tablespoon at a time, mixing until the frosting reaches a smooth, spreadable consistency.
- Stir in vanilla extract if using. Add gel food coloring and mix until evenly colored.
- Spread over completely cooled sugar cookies and add sprinkles immediately. Allow frosting to set for 20–30 minutes before stacking.
Notes
- Frosting begins to set within 5 minutes. Work quickly.
- If frosting thickens too fast, add a few drops of milk.
- Do not refrigerate iced cookies to prevent condensation.
- Best used on completely cooled cookies.
