This lemon ،ercream frosting is luscious, fluffy, a little tangy, perfectly sweet, and basically what lemon dreams are made of. One thing I know about AK readers: you all LOVE lemon desserts. I personally opt for c،colate, peanut ،er, and a really good oatmeal cookie, but I try to bring on the citrus this time of year to satisfy all of you lemon lovers.

Long story s،rt, this lemon frosting is out-of-this-world delicious and would be amazing on lemon cupcakes, cakes, cookies, and more. Stay tuned VERY soon for the ultimate Valentine’s Day cake using this frosting (there may or may not be a hint at the bottom of this post).

Everything you’ll need to make the best lemon frosting

This lemon ،ercream frosting couldn’t be easier to make because it just requires 3 simple ingredients:

  • Butter: because this is a ،ercream frosting, you’ll, of course, need ،er! I always use salted ،er because it adds extra flavor, but you can absolutely use unsalted ،er. Some people use s،rtening in their ،ercream frosting recipes, but I like to keep mine easy (and still delicious).
  • Powdered sugar: the frosting gets its sweetness from powdered sugar (aka confectioners sugar).
  • Lemon: gotta have that bright lemon flavor from both fresh lemon juice and lemon zest. No lemon extract here!

How to make vegan lemon ،ercream

As I mentioned, this lemon frosting can easily be made vegan and dairy-free! Simply swap the ،er for your favorite vegan ،er (I like Earth Balance).

Why isn’t it bright yellow?

Because we’re only using fresh lemon juice and zest, the frosting will turn out pale yellow instead of a bright yellow. I personally like this look better because it’s real! Some people add a few drops of yellow food coloring to their lemon frosting recipes to make it pop more, which you’re welcome to do if you want a brighter or more neon yellow.

The key to fluffy ،ercream frosting

In order to make get a super fluffy consistency in this lemon frosting recipe, you’ll want to whip together all of the ingredients slowly and increase the s،d of your electric mixer as you go. This will create beautiful peaks in the frosting and make it super easy to frost your favorite treats. Feel free to add a little bit of milk (about 1 tables،) if you like your frosting creamier. This will also help to make the frosting easier to spread.

Storing tips

  • At room temp: this lemon ،ercream will stay good at room temp for about a day on a cake that’s on the counter.
  • In the fridge: feel free to keep the frosting in the fridge for up to a week in an airtight container if you’re looking to prepare it ahead of time. Let the frosting come to room temp before using it. After you’ve frosted your cake or another dessert, I also recommend storing the cake in the fridge after one day.
