It’s CUPCAKE season and this Lemon Buttercream Frosting is a new addiction of mine!

This year at my daughters cupcake and lemonade stand, I decided to do a little experimenting with flavor combinations.

I made 3 different lemon style cupcakes and took them to each of my daughter’s teachers at school to taste test.

Would you believe that not a single one of them complained about having to taste test a variety of cupcake ideas?

Shocking I know.





However I finally decided on a Lemon Lovers Cupcake.

It included a lemon cupcake with a lemon whipped cream filling and a lemon buttercream frosting, topped with a lemon head.

However I couldn’t quite get the lemon whipped cream or the lemon buttercream to taste quite right.

I tried fresh lemon juice, lemon juice and zest and lemon extract.

As a result, all were failures according to my taste buds.

However, after much trial and error an idea came to me.

Would you believe that I just happened to have some lemon curd in my fridge?

If you know me, then this really isn’t much of a shock.

Lemon curd is a pretty regular item in my fridge – if for no other reason than to eat it with a spoon.

However I decided to try experimenting with adding the lemon curd to my frosting and nothing else and see what kind of lemon flavor I would get.

And BAM.

That was it.

A natural tasting lemon buttercream frosting that wasn’t too sweet, wasn’t bitter and wasn’t overpowering.

You taste the lemon but not in an overwhelming way.

It’s light and sweet and oh so tasty!

And there you have it.

A winner.

Sometimes (and by sometimes I mean always) cupcake and frosting experiments take several rounds of experimenting.

However eventually, if I don’t give up, I find the perfect combination and give myself a gold star.

If you love lemons and are looking for a lemon frosting that isn’t going to overpower your guests, try this one.

It’s a favorite of ours and we hope it will be yours too!

    • Pam! Thank you so much for pointing this out! I’ve fixed it. It’s 1/2 cup. When I made it I doubled the recipe so my brain kept trying to get me to do 1 cup but that would be a bit much for a single batch. However after your half cup is added, taste test it. If it’s not lemon enough, add a spoonful more. I hope you like this as much as we do! We couldn’t stop eating it!

  1. Awesome! I make lemon milkshakes by adding lemon curd to vanilla ice cream. Perfect balance! I’m trying this lemon buttercream tomorrow. Thanks!

    • Heather that is a GREAT question. I don’t know the answer to it however. I have made it in advance and left it in the fridge, at which point you’ll need to allow it to come to room temperature and give it a quick whip again. But I’ve never tried freezing it. If you do try it, let me know how it turns out!
