Step 1: Prepare the Crust - Start by preheating your oven to 350°F (175°C). In a mixing bowl, combine the keto cookie crumbs, melted butter, and allulose sweetener. Mix until the crumbs are evenly coated. Press the mixture firmly into the bottom and up the sides of a 9-inch pie pan. Bake the crust in the preheated oven for about 10 minutes or until slightly golden. Remove from the oven and let it cool completely.
Step 2: Make the Filling - In a large mixing bowl, beat the softened cream cheese until smooth and creamy. Gradually add the keto condensed milk, continuing to beat until well combined. Mix in the lime juice and blend until fully incorporated. The mixture should be smooth and creamy with a vibrant lime flavor.
Step 3: Whip the Cream - In another bowl, whip the heavy cream until soft peaks form. Gradually add the sugar-free powdered sugar and continue whipping until stiff peaks form. Gently fold the whipped cream into the lime filling mixture, being careful not to deflate the cream.
Step 4: Assemble the Pie - Pour the filling into the cooled crust, smoothing the top with a spatula. Refrigerate the pie for at least 4 hours, or until set. This allows the flavors to meld beautifully and the filling to firm up.
Step 5: Serve and Enjoy - Once set, slice the pie and garnish with fresh lime slices. Serve chilled and watch as your guests indulge in this delightful Keto Key Lime Pie.
