Ingredients

Scale

Buttercream Base

  • 1 cup (226g) unsalted butter, room temperature
  • 3 1/2 cups (420g) powdered sugar
  • 2 tsp (10ml) whole milk, room temperature
  • Pinch of salt, or to taste

Flavoring

  • 2 tbsp (30ml) fresh lemon juice (about 1/2 of a large lemon)
  • 12 drops yellow food color gel (optional)

Instructions

  1. Whip Butter: In a stand mixer fitted with the paddle attachment, whip the room temperature unsalted butter on high speed for about 5 minutes until it becomes creamy and light in color. This step aerates the butter to create a smooth base.
  2. Add Powdered Sugar: Gradually add the powdered sugar in two portions, mixing thoroughly for about a minute after each addition. Be sure to scrape down the sides of the bowl and paddle to ensure even mixing and a consistent texture.
  3. Incorporate Lemon Juice and Milk: Pour in the fresh lemon juice, whole milk, and a pinch of salt. Mix on low speed for 1-2 minutes until the buttercream is smooth and well combined. If desired, blend in 1-2 drops of yellow food color gel to give the frosting a vibrant lemon hue.

Notes

  • Use room temperature butter for the best whipping results and smooth texture.
  • Adjust the amount of lemon juice to taste if you prefer a more or less tangy buttercream.
  • If the buttercream is too thick, add a small amount of milk to reach desired consistency.
  • The optional yellow food coloring helps achieve a classic lemon buttercream color but can be omitted if coloring is not desired.
  • Buttercream can be stored in an airtight container in the refrigerator for up to 1 week; bring back to room temperature and whip before using.
