Lemon Buttercream Frosting Recipe
Introduction
This Lemon Buttercream Frosting is a bright and creamy topping perfect for cakes and cupcakes. The fresh lemon juice and zest give it a refreshing citrus flavor that balances the sweetness beautifully.

Ingredients
- 1 cup (16 Tbsp; 226g) unsalted butter, softened to room temperature
- 4 and 1/2 cups (540g) confectioners’ sugar
- 2 and 1/2 Tablespoons fresh lemon juice
- 2 Tablespoons heavy cream
- 2 teaspoons lemon zest
- Pinch salt, to taste
Instructions
- Step 1: With a handheld or stand mixer fitted with a paddle or whisk attachment, beat the butter on medium speed until creamy—about 2 minutes.
- Step 2: Add confectioners’ sugar, lemon juice, heavy cream, and lemon zest while mixing on low speed. Increase to high speed and beat for 3 full minutes.
- Step 3: Taste the frosting and add a pinch of salt as needed. If the frosting is too thin, add up to 1/2 cup more confectioners’ sugar. If it’s too thick, add another tablespoon of cream.
Tips & Variations
- Use fresh lemon juice and zest for the best flavor; bottled lemon juice won’t deliver the same brightness.
- For a tangier kick, add a teaspoon of lemon extract in addition to the fresh lemon ingredients.
- Adjust the frosting thickness by adding cream or confectioners’ sugar gradually to reach your desired consistency.
Storage
Store the frosting tightly covered in the refrigerator for up to 1 week, or freeze for up to 3 months. When ready to use after chilling, thaw in the refrigerator, bring to room temperature, and beat again until creamy. If needed, add a little milk or heavy cream to loosen the consistency.

FAQs
Can I use margarine instead of butter?
Butter provides the best texture and flavor for this frosting. Using margarine may affect the creaminess and taste, so it’s not recommended.
How do I make the frosting more lemony?
Increase the lemon zest or add a teaspoon of lemon extract for a stronger lemon flavor without altering the frosting’s texture.
