Step‑by‑Step Instructions for Simple Lemon Curd Frosting
Step 1: Prepare the Lemon Curd
In a medium saucepan, whisk together 4 egg yolks, 6 tablespoons of granulated sugar, 2 teaspoons of lemon zest, and ¼ cup of fresh lemon juice. Cook the mixture over medium heat, stirring constantly until it thickens, which should take about 15 minutes. It’s ready when the curd coats the back of a spoon. Remove from heat and let it cool for about 20 minutes before using.
Step 2: Cream the Butter
In a large mixing bowl, add 1 cup of softened unsalted butter. Using an electric mixer, beat the butter on medium speed until it becomes light and fluffy, approximately 3 to 5 minutes. This step is crucial for achieving a creamy texture in your Simple Lemon Curd Frosting, so ensure the butter is properly aerated before adding any other ingredients.
Step 3: Incorporate the Powdered Sugar
Gradually sift in 3 ½ cups of powdered sugar, mixing on low speed to avoid a sugar cloud. Once incorporated, increase the mixer speed to medium and beat until the frosting is smooth and fluffy, about 2–3 minutes. This step ensures that your frosting has that perfect sweetness and a velvety consistency, making it ideal for spreading.
Step 4: Add Lemon Curd and Zest
Carefully fold in 3 tablespoons of the cooled lemon curd and 1 tablespoon of additional lemon zest into the buttercream mixture. Use a spatula and mix gently until well combined, being careful not to deflate the frosting. This addition enhances the flavor of your Simple Lemon Curd Frosting, making it bold and zesty.
Step 5: Adjust the Consistency
If your frosting is too thick for spreading or piping, add 2 teaspoons of cream or milk. Blend the mixture on low speed until the desired consistency is reached, ensuring it remains creamy but easy to work with. This step allows your Simple Lemon Curd Frosting to perfectly adorn cakes or cupcakes with a luscious finish.

Simple Lemon Curd Frosting Recipe FAQs
What type of lemons should I use for the lemon curd?
Absolutely! When choosing lemons, opt for ones that are firm and heavy for their size with vibrant yellow skin, indicating ripeness. Avoid any lemons with dark spots all over, as they signal overripeness. Fresh, juicy lemons will give your lemon curd the bright flavor you desire.
How long can I store Simple Lemon Curd Frosting?
You can store your Simple Lemon Curd Frosting in an airtight container in the refrigerator for up to 4 days. I often make a batch ahead of time for special occasions, and it stays deliciously creamy throughout. Just ensure it’s well-sealed to keep it fresh.
Can I freeze Simple Lemon Curd Frosting?
Unfortunately, I don’t recommend freezing this frosting because the texture can significantly change upon thawing, often resulting in a grainy consistency. If you’ve made a larger batch, it’s best to store it in the fridge and enjoy it fresh!
What should I do if my lemon curd is too thin?
If your lemon curd is too thin, don’t worry! Simply return it to the stove and cook it over low heat, stirring continuously until it thickens to your desired consistency. Remember, this step takes about 5-10 minutes. Once thickened, cool it completely before incorporating it into your frosting.
Is there any dietary consideration for this frosting?
This Simple Lemon Curd Frosting is vegetarian-friendly! However, if you have allergies, ensure to use unsalted butter labeled as dairy-free for a vegan variation. Additionally, avoid adding kosher salt if you’re watching your sodium intake. If you’re making for pets, keep in mind that the lemon and sugar aren’t suitable for their diets.
Can I adjust the sweetness of the frosting?
Very much so! If you prefer a less sweet frosting, you can start by reducing the powdered sugar to 3 cups instead of 3 ½ cups. Be sure to taste as you go, and you can always add more lemon curd for added zest and flavor balance!
