The Best Lemon Frosting Recipe
This brilliantly flavored lemon frosting strikes the perfect balance between tart and sweet. With it’s pale yellow hue and bright, citrusy flavor, this frosting is a perfect choice for topping spring cakes and cupcakes!
Why You’ll Love This Recipe:
Unlike most lemon frostings that manage a shallow lemon flavor from lemon juice, lemon zest, or even lemon extract, this recipe has a robust flavor from a simple small-batch homemade lemon curd.It spreads and pipes beautifully, much like my classic buttercream frosting. Pairs perfectly with just about any springtime recipe, but especially my lemon blueberry cake!
To make sure the added step of cooking a curd was really worth the effort (a little time on the stovetop has certainly proven worth it for my German buttercream and ermine frosting!), I asked half a dozen of my family members do a blind taste test. When compared to a frosting made with lemon juice and zest, every single person overwhelmingly preferred this version, so I definitely think it’s worth the extra effort! Let’s see if you agree 😊
What You Need
You only need a handful of ingredients for the most flavorful lemon frosting:
Egg yolks. We’ll use these for our lemon curd. Don’t worry–they’ll be thoroughly cooked and safe to eat!Lemon juice. Fresh squeezed lemon juice is best for the most flavorful lemon frosting.Sugar. Compared to my classic lemon curd, you’ll notice that today’s recipe has a lesser amount of granulated sugar. This is intentional, since we’ll need to use powdered sugar later on and we don’t want our frosting to be overwhelmingly sweet. Unsalted butter. Use unsalted butter so we can control the amount of salt in our frosting.
SAM’S TIP: Do not add vanilla extract! It may seem odd to have a frosting recipe without any vanilla extract (even my chocolate frosting has a splash!), but I found that even the tiniest amount of vanilla completely dominated the lemon flavor in this frosting. It’s intentionally missing from this ingredient list, so leave it out! Remember, this is just an overview of the ingredients I used and why.
