  1. Love the lemon frosting. So fresh and lemony. I used it to frost a lemon raspberry cake. So awesome.

  2. Loved this recipe when I first made it for Easter, but it’s no longer the same. Do you have the original one with the cream cheese instead of shortening? I don’t remember if the proportions are the same as just substituting one for the other.

    1. Sure thing Amy. I apologize for the change, some readers were having trouble with the consistency of the original recipe. I’ve included it below for you. Enjoy!

      2 lemons
      1 cup butter
      3 cups powdered sugar
      4 oz cream cheese
      Instructions
      Cream butter with mixer on medium until light and fluffy. Zest lemons and add into butter (you should have about 1 tablespoon lemon zest).
      Juice 1/2 of one of the lemons and add 2-3 tablespoons to butter mixture.
      Add powdered sugar 1/2 cup at a time and beat until light and fluffy. Add softened cream cheese and beat until fluffy.
      Add more lemon juice if required to reached desired consistency.

  3. Under recipe notes you say: “Lemon extract is optional. I prefer to make this frosting without using just the flavor of fresh lemon. ” Please clarify this or correct your Notes. Does it mean you like using the lemon extract in addition to the fresh lemon or that you only use the fresh lemon for flavor???

    1. I apologize for the confusion. The lemon extract is optional and I usually don’t add it.

  4. Followed recipe to the letter, the frosting never got thick even after doubling the amount of powdered sugar. Very disappointed.

    1. I’m so sorry to hear that Kev. I’ve made this recipe many times and haven’t had that issue, so can’t say for sure what went wrong. Did you juice 1/2 of one of the lemons and add only 2-3 Tablespoons of the juice to the butter mixture?

    1. If it’s a few hours, I leave it on the counter. If it’s going to be longer, I refrigerate and then remove from the fridge to soften for a while before serving.

  5. Holly, I actually doubled the recipe. It was FANTASTIC. I agree with others. It is the best frosting EVER! It is so smooth and goes on the cake smoothly. I have never had a recipe for frosting before that was as great as this one is. We loved it! Will definitely be using it a lot more times. Thank you for sharing it with us.5 stars

  6. Mine won’t pipe like in the picture.
    All the same ingredients.
    Do I have to beat longer to thicken?

    1. You shouldn’t have to beat it longer. If the temperature is very warm, it could soften the frosting. You may like to refrigerate it for a little bit first.

  7. Love all your recipe. But we pucker up for lemon in my house doesn’t stay around very long. Just love the icing.

  8. The hey holly, I found your site today and made the lemon buttercream icing and it is absolutely, positively ,unbelievably delicious! This is now my favorite icing of all time. Thank you so much for posting and sharing!

  9. These recipes look delicious, thanks for sharing them, I have tons of zucchini this year, looking forward to trying all your recipes
