Instructions

Cream the Butter: In a large bowl, beat the butter using a hand or stand mixer on medium-high speed for 2–3 minutes until pale and creamy.

Add Sugar: Gradually add powdered sugar, one cup at a time, mixing on low until blended. Beat on medium-high until smooth and lump-free

Incorporate Flavor: Add lemon juice, zest, vanilla, and a pinch of salt. Mix thoroughly to combine.

Adjust Consistency: Mix in 2 tablespoons of cream or milk. Add more liquid for a softer frosting or extra sugar for a thicker consistency.

Final Whip: Beat on high speed for 2 minutes until light and fluffy.

Store or Serve: Use immediately, or refrigerate for up to 5 days. Bring to room temp and re-whip before using.

Notes

Zest for Extra Flavor: Using fresh lemon zest enhances the citrusy aroma and flavor—don’t skip it!
Sift the Sugar: This prevents lumps and ensures a silky-smooth texture.
Adjust Sweetness: If you prefer a tangier frosting, add an extra teaspoon of lemon juice. For a sweeter version, increase powdered sugar slightly.
Best Pairings: Pairs beautifully with vanilla, lemon, or berry-flavored cakes and cupcakes.
Storage: Keep in an airtight container in the refrigerator for up to 5 days or freeze for up to 3 months.
