Lemon Buttercream Recipe

You can’t have a bakery-style lemon cookie without a thick, velvety layer of fresh lemon buttercream on top. 🍋🧁

This is my go-to frosting when I want something incredibly bright, tangy, and perfectly sweet. It whips up so smooth and holds its shape beautifully.

🥣 The Lemon Buttercream Recipe

1 cup butter

3 ½ cups powdered sugar

2 tbsp lemon juice

2 tbsp milk

Yellow food coloring (just a touch!)

Top with sprinkles! ✨

Quick tip: For the absolute best texture, make sure your butter is truly at room temperature before you start whipping it. Add the powdered sugar and liquids alternately so it stays light and fluffy.

... Read moreOne of the best things about this lemon buttercream recipe is how versatile it is. Beyond just topping lemon cookies, I've found it works wonderfully on cupcakes, layer cakes, and even as a filling between cake layers. The key to getting that perfect texture lies in how you handle the butter and sugar. Ensuring the butter is at true room temperature allows it to whip up light and fluffy, which makes it easier to incorporate the powdered sugar without making the frosting dense or greasy. When I make this frosting, I add the lemon juice and milk gradually while mixing on a low speed to keep it airy. This approach helps maintain that smooth consistency without it becoming too runny. If you want a more intense lemon flavor, you can swap some or all of the lemon juice with lemon zest, but be mindful of the texture. The yellow food coloring is a nice touch for presentation, giving the frosting that delightful sunny hue reminiscent of fresh lemons. Don't hesitate to try decorating with colorful sprinkles or even edible flowers to make your baked treats stand out. Also, this buttercream can be stored in the fridge for a few days; just bring it back to room temperature and re-whip before using to regain its fluffy texture. Overall, experimenting with this lemon buttercream has made my homemade desserts look and taste like they came straight from a bakery, impressing friends and family alike.
