Once you have the sugar free graham cracker crusts prepared (see my previous blog post for the recipe), you can fill them any way you choose. I tried making key lime and chocolate cream pies because they are such sweet treats for the summertime, and I wanted to take on the challenge of making them sugar free.
For the key lime pie, I started with a Cooking Light magazine recipe that is a healthier version than many other recipes I reviewed. The trick with a key lime pie is to get the right consistency without using sweetened condensed milk. My online research found that heating evaporated milk with agave nectar could work as a good substitute. Adding Greek yogurt to the filling provides some tang and a thick consistency. This pie takes a while to bake and it will continue to thicken once it is out of the oven and cools. Fresh key lime juice tastes great in this pie although fresh lime juice will work just as well.
Ingredients for Filling:
1/2 cup plain 2% reduced-fat Greek yogurt
1/2 cup fresh Key lime juice (or fresh lime juice)
1/2 teaspoon lime zest
3 large egg yolks
1 (14-ounce) can evaporated milk
1 cup agave nectar
1. Preheat oven to 350°.
2. Combine evaporated milk and agave nectar in a small saucepan. Cook on low heat for approximately 10 minutes. Use approximately 14 ounces (or 1 2/3 cups) of the resulting mixture in the filling in the next step.
3. To prepare filling, place yogurt, lime juice, lime zest, egg yolks, and milk/agave mixture in a bowl; beat with a mixer at medium speed for 2 minutes. Pour mixture into prepared crust. Bake at 350° until set, about 35 minutes. Cool pie completely on a wire rack. Cover loosely, and chill at least 2 hours. Serve with whipped cream.
As for the chocolate cream pie, I again started with a Cooking Light recipe as the base. I substituted the coconut palm sugar for the cane sugar, and used grain sweetened chocolate (Endangered Species or Sunspire are delicious cane sugar free options) instead of the usual store-bought sugary brands. This pie is delicious and had a light and rich texture.
Ingredients for Filling:
2 cups fat-free milk, divided
1/2 cup coconut palm sugar
1/3 cup unsweetened cocoa
3 tablespoons cornstarch
1/8 teaspoon salt
1 large egg
2 ounces (cane sugar free) chocolate, chopped
1 teaspoon vanilla extract
1 teaspoon grated (cane sugar free) chocolate
1. To prepare filling, combine 1/2 cup milk, 2/3 cup palm sugar, and next 4 ingredients (2/3 cup palm sugar through egg) in a large bowl, stirring with a whisk.
2. Heat 1 1/2 cups milk in a heavy saucepan over medium-high heat to 180° or until tiny bubbles form around edge (do not boil). Remove from heat. 3. Gradually add hot milk to sugar mixture, stirring constantly with a whisk. Return milk mixture to pan. Add chopped chocolate; cook over medium heat until thick and bubbly (about 5 minutes), stirring constantly. Reduce heat to low; cook 2 minutes, stirring constantly.
4. Remove from heat; stir in vanilla. Pour into prepared crust; cover surface of filling with plastic wrap. Chill 3 hours or until cold. Remove plastic wrap; spread whipped cream evenly over filling. Sprinkle with grated chocolate.
Serve your favorite pie in a pie plate – or in my case – a pi plate! Pi (pronounced “pie”) is the ratio of the circumference of a circle to the diameter, which is the same value no matter the size of the circle.
