1½ cups plain nonfat Greek yogurt

How to Make Our Weight Watchers No-Bake Key Lime Cheesecake

Combine the crushed biscuits, melted light butter, and sweetener until the mixture resembles wet sand.
Press the mixture firmly into the base of an 8-inch springform pan. Refrigerate for 20 minutes while preparing the filling.
Beat the light cream cheese until smooth and creamy.
Mix in the Greek yogurt, powdered sweetener, lime juice, lime zest, and vanilla extract until completely combined.
Stir in the prepared gelatin if using. This helps the cheesecake slice neatly after chilling.
Pour the filling over the chilled crust and smooth the top with a spatula.
Refrigerate for at least 4 hours or overnight until fully set.
Decorate with lime slices, additional zest, or a dollop of light whipped topping before serving.

This refreshing Weight Watchers dessert is perfect for summer entertaining, healthy celebrations, or satisfying a cheesecake craving without the heaviness of a traditional recipe.
