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

1. 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.
2. 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.
3. 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.

Instructions

1. Beat the Butter: Using a handheld or stand mixer fitted with a paddle or whisk attachment, beat the softened unsalted butter on medium speed until creamy, which should take about 2 minutes.
2. Add Ingredients: With the mixer running on low speed, gradually add the confectioners’ sugar, fresh lemon juice, heavy cream, and lemon zest to the butter.
3. Whip the Frosting: Increase mixer speed to high and beat the mixture for 3 full minutes until smooth and fluffy.
4. Adjust Consistency: 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 too thick, add an additional tablespoon of heavy cream.
5. Store Properly: Cover the frosting tightly and refrigerate for up to 1 week or freeze for up to 3 months.
6. Recondition Before Use: When ready to use after refrigeration or freezing, thaw in the refrigerator, bring to room temperature, and beat the frosting briefly to restore its creamy texture. Add a little milk or heavy cream if still stiff.

Notes

• Use fresh lemon juice and zest for the best bright citrus flavor and aroma.
• For a thicker frosting, add more powdered sugar gradually; for a thinner consistency, increase the heavy cream slightly.
• If frosting has been frozen, always rebeat after thawing to regain smoothness.
• Butter should be softened to room temperature but not melted to ensure proper creaming.
• This frosting works excellently for lemon cakes, cupcakes, or as a tangy filling between layers.
