How to Make Weight Watchers Key Lime Pie
Follow these simple steps to prepare the perfect pie without the need for baking or complicated ingredients.
- Dissolve the gelatin: In a large bowl, combine the sugar-free lime gelatin with boiling water, whisking gently until fully dissolved. Allow the mixture to cool slightly for optimal texture.
- Mix filling: Add the key lime pie yogurt and fat-free whipped topping into the bowl. Stir thoroughly with a wire whisk to ensure even blending and smooth consistency.
- Prepare the crust: Pour the whipped, creamy filling into the reduced-fat graham cracker crust. Use a spatula to spread evenly.
- Chill: Refrigerate the pie for a minimum of two hours. Chilling allows the filling to set, resulting in a firmer and more cohesive texture when sliced.
- Serve: Slice the pie into eight equal portions. Serve chilled and garnish if desired.

The pie stays fresh for up to 3-4 days, provided it is kept covered and chilled. The crust may begin to soften after the first couple of days, but flavor remains.
