For the Frosting

Unsalted Butter – Provides a rich, creamy base; make sure it’s softened for easy mixing.
Confectioner’s Sugar – Sweetens and adds fluffiness; sift it to ensure a smooth texture.
Lemon Extract – Delivers that zesty lemon punch; more zest can be used for a fresher flavor.
Citric Acid – Boosts tartness for a punchy lemon flavor; adjust to taste or omit if you prefer a milder sweetness.

Step‑by‑Step Instructions for Lemon Buttercream

Step 1: Soften the Butter
Begin by taking your unsalted butter out of the refrigerator and allow it to soften at room temperature for about 30 minutes. You’ll know it’s ready when it’s slightly soft to the touch but not melted. This will help create a creamy texture in your lemon buttercream frosting.

Step 2: Whisk the Butter
In a stand mixer fitted with a paddle attachment, beat the softened butter on high speed for 6 to 9 minutes, until it becomes fluffy, pale, and creamy. You’ll want to see it nearly double in volume. Scrape down the bowl halfway through to ensure even mixing for your delightful lemon buttercream.

Step 3: Add Confectioner’s Sugar
Gradually incorporate the sifted confectioner’s sugar into the whipped butter on low speed. Mix until the sugar is fully combined, which usually takes about 1 to 2 minutes. Once incorporated, increase to high speed and whisk for an additional 3 to 4 minutes until your frosting is light and airy.

Step 4: Flavor with Lemon Extract and Zest
Now it’s time to add the vibrant flavors! Add the lemon extract, citric acid, and lemon zest to your mixture. Whisk on medium speed for another 2 to 3 minutes, scraping down the bowl as needed to ensure everything is well combined, and the lemon buttercream is bursting with zesty goodness.

Step 5: Final Whisk for Fluffiness
Give your lemon buttercream a final whisk on high speed for about 1-2 minutes. This step ensures that all ingredients are thoroughly combined and that your frosting has reached the perfect fluffy texture. Check that it’s light, creamy, and ready to adorn your favorite cake or cupcakes!

Step 6: Store or Use Immediately
Once your lemon buttercream is ready, you can either use it immediately to frost your cakes or cupcakes or store it. If saving, place it in an airtight container and refrigerate it for up to a week. When ready to use again, give it a gentle stir or re-whisk to restore its creamy consistency.

Make Ahead Options

These Zesty Lemon Buttercream Frosting preparations are ideal for busy home cooks looking to save time without sacrificing flavor! You can prepare the frosting up to 3 days in advance, allowing the flavors to meld beautifully. To do this, whip the frosting as directed, then store it in an airtight container in the refrigerator to maintain its fresh taste and fluffy texture. When it’s time to use, simply take it out and let it sit at room temperature for about 15 minutes before re-whisking gently to restore its creamy consistency. You’ll enjoy a perfectly delightful lemon buttercream that’s just as delicious as if you made it fresh!
