Looking for a delightful dessert that combines the tangy zest of citrus with a creamy base? Ww Key Lime Pie Bars are a refreshing treat, perfect for any occasion. With their luscious filling and buttery crust, the bars are sure to brighten your day.

For a richer flavor, consider using regular cream cheese instead of fat-free, though that will increase the calorie count. If you’re looking for a gluten-free option, swap the all-purpose flour for a gluten-free blend. Fresh key limes provide the best flavor, but if they are unavailable, regular limes can be used as a substitute.

Ww Key Lime Pie Bars Recipe
Ingredients
- 3 tablespoons margarine, softened
- 3 tablespoons fat free cream cheese
- 1 1/2 cups sugar
- 1 large egg yolk
- 3/4 all-purpose flour
- 2 tablespoons all-purpose flour
- 3 tablespoons powdered sugar
- 1 large egg
- 1/4 cup fat free egg substitute
- 1/3 cup fresh lime juice, from key limes
Instructions
- Preheat your oven to 350 degrees Fahrenheit.
- Coat an 8-inch square baking dish with cooking spray to prevent sticking.
- For the crust, beat together 3 tablespoons of softened margarine, 3 tablespoons of fat-free cream cheese, and 1/2 cup of sugar with an electric mixer until the mixture becomes light and fluffy.
- Add 1 large egg yolk and gradually mix in 3/4 cup of all-purpose flour until combined.
- Spread the crust mixture evenly into the prepared baking dish using your hands. To avoid sticking, coat your hands with 1 tablespoon of powdered sugar.
- Bake in the preheated oven for about 15 minutes, or until the crust is lightly browned.
- While the crust bakes, prepare the filling by beating 1 large egg and 1/4 cup of fat-free egg substitute in the same bowl used for the crust.
- Add the remaining 1 cup of sugar and 2 tablespoons of all-purpose flour to the egg mixture, then beat on low speed until everything is well blended.
- Stir in 1/3 cup of fresh lime juice and continue to beat on low until combined.
- Once the crust is ready, pour the lime filling into the warm crust and bake for an additional 15 minutes.
- After baking, allow the bars to cool completely and sprinkle with 2 tablespoons of powdered sugar before slicing into squares.
