Step-by-Step Instructions for Lemon Sweetened Condensed Milk Buttercream
Step 1
Start by placing your softened unsalted butter into a large mixing bowl. Using an electric mixer, beat the butter on medium speed for about 2-3 minutes until it becomes light and fluffy. This step is crucial as it creates the base for your Lemon Sweetened Condensed Milk Buttercream, ensuring a rich and creamy texture that will help your frosting spread beautifully.
Step 2
Gradually add in the powdered sugar, lemon juice, and lemon extract. Continue mixing on low speed to prevent a sugary cloud from forming, and blend for about 3-4 minutes until well combined. The mixture should start to take on a thicker consistency, and the lovely lemon scent will begin to fill your kitchen, hinting at the delightful flavor awaiting in your buttercream.
Step 3
Now, it's time to introduce the sweetened condensed milk to your mixture. Add it in tablespoon increments, mixing well after each addition. This step typically takes about 5-7 minutes, allowing the frosting to achieve a silkier consistency. The sweetened condensed milk is what makes this Lemon Sweetened Condensed Milk Buttercream uniquely creamy, setting it apart from traditional frostings.
Step 4
Assess the consistency of your buttercream at this point. If it feels too thick, add a splash more lemon juice for tanginess or an extra tablespoon of sweetened condensed milk to loosen it. If it’s too runny, gradually insert more powdered sugar until you reach your desired thick and spreadable texture. The buttercream should hold its shape yet spread smoothly with a vibrant lemon hue.
Step 5
For an added burst of fresh flavor, (if desired), stir in the lemon zest at this stage. Using a spatula, incorporate the zest slowly into the frosting, making sure it is evenly distributed. This final touch enhances the flavor profile of your Lemon Sweetened Condensed Milk Buttercream and adds a delightful, cheerful speck of color.
Step 6
Your Lemon Sweetened Condensed Milk Buttercream is now ready for use! Spread a generous layer over your cooled cakes or cookies, using a spatula or a piping bag for decorative flair. Take a moment to admire your lovely, fluffy creation before sharing it with family and friends. Enjoy the bright, sunny taste of your delicious frosting on any dessert you cherish!

Lemon Sweetened Condensed Milk Buttercream Recipe FAQs
Can I add sweetened condensed milk to buttercream?
Absolutely! Sweetened condensed milk adds a unique creaminess and richness to your buttercream, making it smoother and more velvety. It’s particularly useful in this Lemon Sweetened Condensed Milk Buttercream, where it complements the lemon flavor perfectly.
What happens when lemon juice is added to condensed milk?
When lemon juice is added to sweetened condensed milk, it creates a deliciously tangy balance that cuts through the sweetness. In baking, this combination can also help thicken or stabilize mixtures, making it ideal for frostings like our lemon buttercream.
Will condensed milk curdle with lemon?
Not necessarily! Sweetened condensed milk is thick and syrupy, and adding lemon juice should not cause curdling like fresh milk might. However, make sure to mix them well to create a creamy consistency in your frosting.
What does adding sweetened condensed milk do to cake mix?
Adding sweetened condensed milk to cake mix gives it a richer taste and moisture. It can enhance the flavor profile while adding a tender crumb, creating a lusciously soft cake.
Why is my condensed milk buttercream runny?
If your buttercream turns out runny, it could be due to too much liquid in the mix. To fix this, gradually add more powdered sugar until you achieve the right consistency. Allow the frosting to sit for a few minutes; it may thicken as it settles.
What is German buttercream?
German buttercream is a delicious blend that combines butter, milk, and sugar with egg yolks, resulting in a richer, creamier frosting than traditional buttercream. It's an amazing alternative if you're looking to explore different buttercream styles!
