Step‑by‑Step Instructions for Simple Lemon Curd Frosting

Step 1: Prepare Lemon Curd
In a medium saucepan over medium heat, whisk together egg yolks, granulated sugar, lemon zest, and fresh lemon juice until they are well combined. Continuously stir the mixture for about 10 minutes, or until it thickens enough to coat the back of a spoon. Once thickened, remove it from heat and let it cool for 20 minutes in the refrigerator to set.

Step 2: Make Frosting Base
In a large mixing bowl, beat 1 cup of softened unsalted butter with an electric mixer on medium speed for about 2 minutes, or until the butter becomes creamy and smooth. This step is crucial for achieving a light texture in your Simple Lemon Curd Frosting, so take your time to ensure it’s fluffy and paler in color.

Step 3: Combine Ingredients
Gradually add the sifted powdered sugar to the creamy butter, beating on low speed until fully incorporated. Then, fold in the prepared lemon curd along with 1 tablespoon of additional lemon zest. Finally, drizzle in 2 teaspoons of cream or milk to adjust the consistency as you mix. The mixture should be smooth and well combined.

Step 4: Adjust Texture/Flavor
Taste your Simple Lemon Curd Frosting and decide if it needs a tangier kick or a sweeter note. If it’s too sweet for your liking, fold in another tablespoon of lemon curd. Conversely, if you desire more sweetness, add up to ½ cup more sifted powdered sugar until it meets your taste preferences.

Step 5: Chill/Use
Transfer the frosting into an airtight container and refrigerate for up to 4 days. When you’re ready to use it, allow the frosting to sit at room temperature for about 15-20 minutes. If it appears too firm when you take it out of the fridge, rewhip it briefly to restore that luscious, creamy texture.

Fridge: Store your Simple Lemon Curd Frosting in an airtight container for up to 4 days. Allow the frosting to sit at room temperature for 15-20 minutes before rewhipping to restore texture.

Airtight Storage: Always ensure that your container is well-sealed to prevent any absorption of odors from the fridge, keeping the frosting fresh.

Reheating: If the frosting becomes too firm, simply rewhip briefly and add a splash of cream or milk to regain its creamy texture.
