These healthy key lime parfaits are a bright, refreshing snack or dessert for warm days when you want something sweet. A graham cracker crumble forms the base, topped with layers of vanilla Greek yogurt blended with whipped topping, key lime juice, lime zest and a touch of vanilla. Finished with shredded coconut, these parfaits deliver the tangy-sweet flavor of key lime pie in a lighter, ready-in-minutes form.

About these healthy key lime parfaits
Creating lower-calorie desserts can be a challenge, especially if you avoid zero-calorie sweeteners and many sugar substitutes. I developed this recipe to satisfy a sweet tooth without a heavy calorie or points hit. These parfaits look special, taste indulgent, and are an easy, lighter take on classic key lime pie.
Flavor and texture
The flavor mirrors key lime pie—tart, sweet and aromatic—while the texture is lighter. Traditional key lime pie relies on sweetened condensed milk and egg yolks to achieve a dense custard. To cut calories, this recipe replaces the condensed milk with a mix of vanilla Greek yogurt and fat-free whipped topping, yielding an airy mousse-like filling that still captures the pie’s signature taste without the extra fat.

Ways to reduce calories further
If you want an even lower-calorie version, choose a vanilla yogurt made with sugar alternatives or a zero-sugar option and skip the coconut garnish. The recipe already uses light butter and fat-free whipped topping to keep calories down; each parfait is about 190 kcal. They’re a satisfying treat that won’t derail a weeknight plan or a lighter dessert menu for guests.
Ingredients you’ll need
Gather the following:
- Graham cracker crumbs (3 oz)
- Light butter (2 tbsp)
- Fat-free whipped topping (8 oz)
- Vanilla Greek yogurt (10 oz)
- Key lime juice (1/4 cup) — note: not the same as regular lime juice
- Vanilla extract (1 tsp)
- 2 limes, zested
- Coconut flakes (3 tbsp), for garnish
How to make these parfaits
1. Melt the light butter in a small bowl. Mix it with the graham cracker crumbs until the texture resembles damp sand. Divide the mixture evenly among six glasses or mason jars and press lightly to form the base.
2. Zest two limes. Reserve half the zest for the filling and the other half for garnish.
3. In a large bowl, combine the vanilla Greek yogurt, fat-free whipped topping, the zest of one lime, key lime juice and vanilla extract. Stir gently until the mixture is smooth and airy.
4. Spoon or pipe equal portions of the yogurt mixture over the graham cracker bases in each glass.
5. Garnish with remaining lime zest and a sprinkle of coconut flakes. Cover and refrigerate; parfaits will keep for several days.
