Lemon Sweetened Condensed Milk Buttercream Ingredients

For the Buttercream
• Butter – Use softened butter for easy blending and to achieve that rich creaminess.
• Powdered Sugar – Adds sweetness and aids in forming a light crust; feel free to adjust based on your desired sweetness level.
• Lemon Extract – Intensifies the lemon flavor; consider adding fresh lemon zest for an extra citrusy punch.
• Sweetened Condensed Milk – Provides unique creaminess and fluffiness, making this buttercream a standout choice in easy frosting recipes.

Step‑by‑Step Instructions for Lemon Sweetened Condensed Milk Buttercream

Step 1: Beat the Butter
Start by placing 1 cup of softened butter in a large mixing bowl. Using an electric mixer, beat the butter on medium speed for about 2-3 minutes until it’s light and fluffy. You’re looking for a pale color and creamy texture that will create a rich base for your Lemon Sweetened Condensed Milk Buttercream.

Step 2: Add Powdered Sugar and Flavor
Gradually add 4 cups of powdered sugar to the beaten butter, one cup at a time. Mix on low speed until combined to avoid a sugar cloud, then increase to medium speed. Next, incorporate 2 teaspoons of lemon extract along with 2 tablespoons of fresh lemon juice, mixing for another 1-2 minutes until the mixture is smooth and well-blended.

Step 3: Incorporate Sweetened Condensed Milk
Slowly add ½ cup of sweetened condensed milk to the butter mixture, one tablespoon at a time. Continue to mix on medium speed for about 2-3 minutes until the frosting becomes light and airy. Keep an eye on the consistency; it should be creamy yet spreadable, perfect for your frosting needs.

Step 4: Adjust Consistency
If the buttercream is too thick, gradually mix in an additional teaspoon of lemon juice until you achieve your desired consistency. Alternatively, if it’s too runny, you can add more powdered sugar by the tablespoon as needed. This adjustment enables you to personalize your Lemon Sweetened Condensed Milk Buttercream to fit any frosting project.

Step 5: Add Zest for Extra Flavor
For an extra zing, stir in finely grated lemon zest from one lemon. This optional step enhances the lemon flavor and adds a delightful texture to the frosting. Mix just until combined for a beautifully zesty finish that will make your buttercream truly shine.

Step 6: Frost and Enjoy
Once your frosting is complete, use it immediately to frost cooled cakes or cookies. Spread generously using a spatula or pipe it onto your treats as desired. The vibrant color and fresh lemon scent will elevate each dessert, making your Lemon Sweetened Condensed Milk Buttercream a delightful crowd-pleaser.

How to Store and Freeze Lemon Sweetened Condensed Milk Buttercream

Fridge: Store leftover buttercream in an airtight container in the refrigerator for up to 2 weeks. Make sure to cover it tightly to prevent it from absorbing odors.

Freezer: For longer storage, freeze the buttercream in a freezer-safe container for up to 3 months. Thaw it in the fridge overnight before using for the best texture.

Reheating: Before using stored frosting, bring it to room temperature. Give it a good stir to restore its creamy consistency, ensuring your Lemon Sweetened Condensed Milk Buttercream is fluffy and ready to shine!

Make Ahead Options

This Lemon Sweetened Condensed Milk Buttercream is perfect for prepping ahead, saving you precious time on busy baking days! You can make the buttercream up to 3 days in advance; simply store it in an airtight container in the refrigerator. To maintain its delightful texture, be sure to give it a quick remix before using. If making earlier, consider holding off on adding the lemon zest until right before serving to keep its fresh flavor intact. When ready to frost your cakes or cookies, take it out of the fridge about 15-30 minutes prior to use, allowing it to soften and return to that fluffy, creamy consistency that makes this buttercream so irresistible!

Expert Tips for Lemon Sweetened Condensed Milk Buttercream

Use Softened Butter: Ensure your butter is at room temperature for optimal creaminess. Cold butter can result in lumps in your Lemon Sweetened Condensed Milk Buttercream.
Gradual Sugar Addition: Add powdered sugar one cup at a time to prevent a messy sugar explosion. Blend gradually for a smooth texture.
Taste and Adjust: After mixing in the sweetened condensed milk, taste your frosting. Add more lemon juice for tartness or powdered sugar for sweetness until you find the perfect balance.
Chill When Needed: If your frosting feels too soft, chill it in the refrigerator for about 15 minutes. This helps it firm up, making it easier to spread or pipe.
Cool Cakes First: Always let cakes or cookies cool completely before frosting. This prevents the buttercream from melting and losing its fluffy texture.
