Step 1

To a large bowl add in unsalted butter and using an electric mixer (hand or stand mixer are both fine - use the paddle attachment if using a stand mixer) cream for a few minutes on a medium high speed until it's light and fluffy.

Step 2

Add in the powdered sugar in 3 batches while mixing on low. Ensure that each batch of powdered sugar is mixed into the butter well before adding in the next batch.

Step 3

Next add in your cold cream cheese, vanilla and fresh lemon juice and mix on a medium speed just until the frosting is smooth. Avoid over-mixing (see note 3). If using a stand mixer, you may need to mix on a high speed to get everything nice and smooth (see note 4 if your frosting is lumpy).
