In a medium sized bowl, mix half of a Sugar Cookie Mix, following the package directions.
Line the Bottom of a 9 inch Spring-form pan with Parchment paper, and press the Sugar Cookie Mix into the bottom of the pan, evenly, smoothing the dough with a spoon. Place the pan in the Oven and bake at 350 degrees for about 20 minutes, or until cookie dough is completely done, and browned on the top and edges. Remove from oven, and gently press the dough down evenly on top with the bottom of a smooth glass. Set pan in the Freezer to cool quickly.
In the mixing bowl of a stand mixer, place the Heavy Cream, 3 Tablespoons of Powdered Sugar, and whip with the Whisk attachment until stiff peaks form, and the Cream is whipped. Add the Vanilla and the Cream Cheese, and blend until smooth and fluffy. Add the Sugar, and Torani White Chocolate Syrup, and mix until smooth.
In a small dish, add 1/3 cup of water, and sprinkle the Unflavored Gelatin over the water, and let the Gelatin 'bloom' for about 3 minutes, or until the gelatin has absorbed the water. Stir the Gelatin to mix, and add the Gelatin to the mixer. Blend well to make sure Gelatin is blended into the Cheesecake batter.
Divide the Cheesecake batter in half, and place several drops of Aqua Food Coloring Gel in one half of the batter, and stir well to mix. Remove the spring-form pan from the Freezer, and pour the Aqua Cheesecake Batter into the pan on top of the Sugar Cookie Crust. Place the pan back in the Freezer until firm, about 3 hours.
In the remaining half of the Cheesecake Batter, add the Lime Green Food Coloring Gel several drops at a time until you get the desired color. Place the Lime Green Cheesecake Batter in the refrigerator until it's time to pour into the pan. When the Aqua Cheesecake is set, or firm to the touch, remove the pan, and pour the Lime Green Cheesecake Batter into the pan, on top of the Aqua layer, and place the pan back in the Freezer, over night.
