Tips for Lemon Buttercream Frosting
- If you’d like a thinner consistency, add a bit more lemon juice.
- For a thicker consistency, add more powdered sugar.
- Make sure your cake or cupcakes are completely cooled before using.
- If you’re spreading this on a 9×13 cake or another use where it doesn’t need to hold its shape, you can add 2 ounces of cream cheese along with the butter for a little tang. If you add the cream cheese, it won’t hold its shape as well when piped.

Pretty easy to do and taste is great!
So happy you enjoyed it!
So delicious and super easy. Love the subtle lemon flavor – not overpowering or puckery! :) Your baking recipes really have brought me back home to homemade everything. I’ve learned to enjoy buttercreams again. Bakery stuff NEVER comes close to homemade. Thank you. Once again.
I made this cream for the Banana Cupcakes (also your recipe). The combination is awesome and I’m not much of a lemons lover, but this frosting lemon is absolutely delicious! And the cupcakes are sooo fluffy! Thank you!
You’re welcome Cristina! I love that combination too!
Did everything you said but it came out to juicy . I had also added more sugar to thicken it but no good.
It tasted good but couldn’t spread it too runny , destroyed my cake.
Did you use only 2 tablespoons of the lemon juice?
