I made this fruit dip for Arden’s St. Patrick’s Day party at preschool (I brought green fruit – apples and grapes – and dip) and it was a huge hit. It tastes just like cheesecake and is incredibly easy to make up. If you made it with a little less cream, it would make a perfect frosting for cupcakes as well.

Cheesecake Dip
8 oz cream cheese
1/2 cup heavy cream
1/4 cup sugar
2 tsp. lemon juice
1 tsp. grated lemon zest
1/4 tsp. vanilla

Heat over medium-low heat in a small pot until smooth, stirring frequently. A whisk helps to break up lumps easily. Cool to room temperature and serve.
