Key Lime Tarts

I have to give all of the credit for this recipe from Angel. She does a homemade blondie brownie for the crust but I take the easy way out...

Ingredients:
sugar cookie mix
1 medium size tub of whipped topping
1 block cream cheese
1/4 Cup powdered sugar
4 squares of Bakers white chocolate
1 lime
optional:green food coloring, granulated sugar, lime for garnish

For crust:
Prepare cookie mix as directed. I do prefer to use the mix because it has more butter than the roll cookie dough thus making it easier to get out of the pans. Spray pan with cooking spray, even if it is a nonstick pan. Use mini muffin pan and fill each cup about half way with dough. Sprinkle a pinch of sugar on top of each ball of dough. Bake at 350 degrees for about 5-7 minutes. Let cool.

For filling:
Put cream cheese in a large bowl and microwave it for a few seconds to get it nice and smooth. Melt squares of white chocolate in microwave. Add chocolate to the cream cheese. Add powdered sugar and the zest of 1 lime to the cheese mixture and stir together. Fold in whipped topping. I also add 1 drop of green food coloring so people know that it's lime filling but that is optional. You can also add more whipped topping if you like a lighter filling.

If any of the crust get stuck in the mini muffin pan, gently slide a butter knife around the edges and it should release the crust. Put on a plate and pipe the filling on the top of each crust. You may want to garnish with lime zest or cut wedges of lime to dress up your plate.
