Ingredients You’ll Need
NOTE: Full ingredient amounts and instructions appear in the printable recipe card below.
Jump
- Butter – The base of the buttercream. Use room-temperature butter for the creamiest texture. Salted or unsalted will work; see notes for salt adjustments.
- Powdered sugar – Adds sweetness, stability, and volume to the frosting.
- Lemon zest and fresh lemon juice – Both add bright, natural citrus flavor. Fresh ingredients give the best aromatic result.
- Milk or heavy cream – Used to thin the frosting and achieve the right spreading or piping consistency.
How to Make Lemon Frosting
- Beat: Place room-temperature butter in a large bowl. Beat with an electric mixer until smooth and creamy, scraping down the bowl as needed.
- Add: Add the powdered sugar, lemon zest, lemon juice, and milk or cream.
- Mix: Beat until the powdered sugar is fully dissolved and the frosting is smooth. If the frosting feels too thick, add milk or cream a half tablespoon at a time until you reach your desired consistency.
Pro tip: Use a spatula to press out any air pockets and smooth the frosting before piping. If piping, chill briefly to make edges crisper, then rewhip slightly if needed.
That’s all it takes. In a few simple steps you’ll have a creamy, lemon-forward buttercream ready to spread or pipe on your favorite desserts.

Storage and Freezing
- To store: Keep leftovers in an airtight container in the refrigerator for up to 5 days. Before using, allow the frosting to soften at room temperature and stir or rewhip briefly to restore a smooth texture.
- To freeze: Spoon the frosting into an airtight, freezer-safe container or a zip-top bag, removing excess air. Freeze for up to 3 months. Thaw in the refrigerator overnight, then bring to room temperature and re-whip by hand or with a mixer to revive the original consistency.
Recipe Notes
Follow these simple tips for bakery-quality lemon buttercream:
- Room temperature butter blends more evenly and gives a lighter, fluffier frosting. Avoid using melted butter.
- Fresh lemons provide the best flavor. Fresh zest captures essential oils that bottled extracts cannot replicate.
- Salt matters — if using unsalted butter, add a small pinch (about 1/4 teaspoon) of salt to balance sweetness. If you prefer less salt, start with 1/8 teaspoon and adjust.
- Only zest the yellow peel — avoid the bitter white pith beneath the peel when grating zest.
- Yield: The recipe makes approximately 2 1/2 cups of frosting, enough to frost about 18 cupcakes or provide a thin layer on a 9×13-inch sheet cake. For a two-layer cake, increase the recipe by 50% or add another cup of powdered sugar and 2–4 tablespoons milk or cream as needed to reach the desired volume and stiffness.
What Desserts Pair Best with Lemon Buttercream?
This lemon buttercream pairs wonderfully with a wide range of desserts.

FAQs
Yes. The frosting will still taste of lemon from the juice, but the zest adds concentrated lemon oil and aroma that make the flavor more pronounced. For the brightest lemon profile use both zest and juice.
Absolutely. This frosting holds its shape well for piping decorations, borders, and cupcakes. It develops a slight crust that helps maintain detail. Chill briefly if you need stiffer peaks for intricate piping.
Bottled lemon juice can be used in a pinch, but fresh-squeezed lemon juice and fresh zest provide the best flavor and aroma.
