In a large bowl using an electric mixer mix the heavy whipping cream until stiff peaks form.
In another bowl combine the cream cheese, granulated sugar, sour cream and vanilla until smooth.
Using your mixer combine the heavy whipping cream into the cream cheese mixture until well combined.
Separate the batter into 4 bowls and dye each one a different color. Stir to blend the color evenly into the mixture.
Place the different batter in individual ziploc bags and snip off the ends.
Pipe one color into 6 of the silicone molds.
Bang the mold on the counter to level the batter.
Repeat with the colors until almost at the top of the mold.
In a microwave safe bowl melt your butter.
To the butter add the graham cracker crumbs and 1 tablespoon of sugar.
Spoon some of the graham cracker mixture onto the top of each cheesecake pressing the crumbs into the batter.
Place the mold onto a tray and place in the freezer for 2-4 hours.
Remove the cheesecakes from their molds, garnish and serve!
I like to top these with a dollop of whipped cream, sprinkles and a little chocolate egg.
