In the bowl of a mixer beat the cream cheese and butter until smooth and fluffy, start on medium-low speed then increase to high.

Add in the powdered sugar and salt. Start by mixing on low so it doesn't make a mess.

Then add in the flavor. Add two tablespoons and mix in the flavor very well, then taste it and see if you need more.

Typically I add a tablespoon or two of heavy cream to whip the frosting up but since there is the additional liquid in the strawberry syrup or curd it's not necessarily this recipe, but if you are only adding extract and want to add heavy cream go right ahead.

This frosting can be thickened by adding up to a cup of powdered sugar without making it overly sweet. The cream cheese and salt help balance the flavor.
