  • Author: Mellissa Sevigny
  • Total Time: 32 minutes
  • Yield: 12 servings 1x


The creamy, luscious filling in this Keto Pistachio Pudding Pie doesn’t require cooking, making this delicious low carb pudding pie fast and easy. Gluten Free.



For the pie crust:

For the filling and garnish:

  • 8 ounces mascarpone cheese
  • 1.5 cups heavy whipping cream
  • 1.5 cups unsweetened almond milk
  • 2 packages sugar free pistachio pudding mix
  • 2 tablespoons confectioners style powdered erythritol
  • 1/2 teaspoon vanilla extract
  • 3 tablespoons chopped pistachios for garnish


For the crust:

  1. Preheat the oven to 350 degrees F. (while waiting for the oven to heat, consider doing step one of the filling prep, which will allow for chill time.)
  2. Press the pistachio shortbread cookie dough firmly along the bottom and sides of a standard sized pie plate.
  3. Bake for 12 minutes.
  4. Remove from the oven and cool.

For the filling and garnish:

  1. Combine the mascarpone, 1/2 cup of the heavy whipping cream, unsweetened almond milk and 2 packages pistachio pudding mix in a large bowl.
  2. Mix well and chill for 15 minutes. (Useful to do this while the crust is baking and cooling)
  3. Meanwhile, combine the remaining 1 cup of heavy whipping cream, 2 tablespoons of  confectioners style powdered erythritol, and 1/2 teaspoon vanilla extract in a large mixing bowl.
  4. Beat with a whisk or electric mixer until stiff peaks form.
  5. Fold half of the whipped cream mixture gently into the pistachio mixture.
  6. Spoon the pistachio mixture into cooled pie shell and smooth out evenly.
  7. Pipe or spoon the remaining whipped cream over the top of the pie.
  8. Garnish with chopped pistachios.
  9. Serve immediately, or chill until ready to serve.


This pie is incredibly rich so a little goes a long way and I kept the serving size at 1/12th of the pie for that reason.  You can obviously eat more, but this is a good starting point for the average person.
