Recipe Yield: Frosts 12–16 cupcakes or 1 standard 8–9″ cake
INGREDIENTS
1 cup unsalted butter, softened to room temperature
4 cups powdered sugar, sifted
4 tbsp heavy cream, plus more if needed
1 tbsp pure vanilla extract
1/4 tsp fine sea salt
INSTRUCTIONS
1. Cream the butter:
In a large mixing bowl, beat the softened butter on medium-high speed for 2–3 minutes until pale, fluffy, and smooth.
2. Add powdered sugar:
Reduce mixer speed to low. Gradually add the sifted powdered sugar, 1 cup at a time, mixing well after each addition to prevent lumps.
3. Add flavor and creaminess:
Pour in the heavy cream, vanilla extract, and sea salt. Increase speed to medium-high and whip for 3–4 minutes until light, airy, and fully combined.
4. Adjust consistency:
If frosting is too thick, add 1 teaspoon of cream at a time until desired spreadable texture is reached. If too soft, add a bit more powdered sugar.
5. Use or store:
Use immediately to frost cakes, cupcakes, or cookies. For later use, refrigerate in an airtight container for up to 1 week. Bring to room temperature and re-whip before frosting.
Helpful Tips to Perfect This Recipe
- Use quality butter: High-fat, European-style butter creates the creamiest and richest flavor for your frosting.
- Sift for smoothness: Always sift powdered sugar to avoid lumps and ensure a silky-smooth buttercream.
- Whip for airiness: Whipping longer gives the frosting a lighter, more luxurious texture—ideal for piping or spreading.
