🧾 Ingredients (Makes enough for 12–18 cupcakes or 1 layer cake)

  • 1 cup (226g) unsalted butter, softened
  • 4 cups (480g) powdered sugar, sifted
  • 2–3 tablespoons (30–45ml) heavy cream or milk
  • 1 teaspoon vanilla extract
  • Pinch of salt, optional (helps cut sweetness)

👨‍🍳 Instructions

1. Cream the Butter

Place the softened butter in a large mixing bowl. Beat on medium speed for about 2 minutes until smooth and creamy.


2. Add Powdered Sugar

Gradually add the sifted powdered sugar, 1 cup at a time, beating well after each addition. Scrape down the bowl often to make sure everything is fully incorporated.


3. Add Vanilla + Cream

Mix in the vanilla extract and a pinch of salt (if using). Slowly add the heavy cream or milk, one tablespoon at a time, until the buttercream reaches your desired consistency—smooth, fluffy, and easy to pipe.


4. Whip It Up

Once everything is combined, increase the mixer to high speed and whip for an additional 2-3 minutes until light and fluffy.


🪄 Tips & Variations

  • Too thick? Add an extra splash of cream.
  • Too thin? Mix in more sifted powdered sugar, 1 tablespoon at a time.
  • Want chocolate buttercream? Add ½ cup sifted cocoa powder or melted chocolate.
  • Bright flavor boost: Add lemon zest, almond extract, or maple syrup.

❄️ Storage Tips

  • Room temp: Store covered at room temperature for up to 1 day.
  • Fridge: Store in the refrigerator for up to 1 week. Bring to room temp and re-whip before using.
  • Freezer: Freeze in an airtight container for up to 3 months. Thaw overnight in the fridge, then bring to room temperature and beat until fluffy.
