Keto Apple Pie Filling:

  • 1/2 cup Butter (salted)
  • 1/4 cup Besti Powdered Monk Fruit Erythritol Blend (or more to taste)
  • 6 tbsp Lemon juice (divided)
  • 2 tsp Cinnamon
  • 1 tsp Nutmeg
  • 1/2 tsp Cardamom
  • 1 tbsp Unflavored gelatin powder
  • 5 medium Yellow squash (~6-7 cups, ~50 oz, peeled, sliced and diced into 1/2 inch pieces; or zucchini!)
  • 1 tsp Vanilla extract (optional)
  • 1/2 tsp Maple extract (optional)

Keto Apple Pie Crust:

  • 3 3/4 cup Blanched almond flour
  • 1/3 cup Besti Monk Fruit Erythritol Blend
  • 1/2 tsp Sea salt
  • 1/2 cup Butter (unsalted, measured solid, then melted)
  • 1 large Egg
  • 1/2 tsp Vanilla extract (optional)
  • 1 tbsp Unflavored gelatin powder
  • 2 tbsp Water


Keto Apple Pie Filling:

  1. In a small pinch bowl, whisk the gelatin powder with 3 tablespoons (44 mL) lemon juice. Set aside to bloom.

  2. In a large 3.5-quart (3.3 liter) saucepan, melt the butter over medium heat. Stir in the powdered sweetener, the remaining 3 tablespoons (44 mL) lemon juice, cinnamon, nutmeg, and cardamom. When the gelatin mixture has thickened, whisk it into the pan, until dissolved.

  3. Add the diced squash to the pan. Bring to a simmer. Simmer over medium heat for about 30-40 minutes, until the squash is very soft and the mixture has thickened, similar to apple pie filling.

  4. Stir in the maple extract.

  5. Set the filling aside to cool until no hotter than lukewarm, at least 20 minutes.

Keto Apple Pie Crust:

  1. Meanwhile, preheat the oven to 350 degrees F (177 degrees C).

  2. To make the pie crust dough, follow steps 1-3 from this almond flour pie crust recipe, BUT you will use the amounts of almond flour, sweetener, sea salt, butter, egg, and vanilla above. (This is an extra amount for the top crust.)

  3. Add the gelatin powder and water, and use a hand mixer to combine, until uniform.

  4. Divide the dough in half. Press half of the dough into the lined pie pan, including the bottom and going up the sides. Set the 2nd half of the dough aside.

  5. Bake the crust in the oven for 10-12 minutes, until just lightly golden.

  6. When done, set aside to cool for at least 10 minutes before adding the filling.

  7. Meanwhile, place the remaining half of the dough between two lightly oiled pieces of parchment paper. Use a rolling pin over the parchment paper to roll out to a circle slightly larger than the top of the pie pan, for the top crust.

Keto Apple Pie Assembly:

  1. Preheat the oven again to 350 degrees F (177 degrees C), if it has cooled. Make sure the filling and bottom crust are both cooled to no hotter than lukewarm before assembling.

  2. Gently transfer the cooled filling to the cooled bottom crust.

  3. Lift the top piece of parchment paper off the rolled out top crust. Using the bottom piece of parchment paper, carefully and rapidly flip the top crust over onto the pie, then gently peel off the parchment paper. Use a knife to cut any excess top crust off the edges, making sure it still completely covers the bottom crust. Use your fingers to press the edges down to seal. Cut 4 slits in the top of the pie.

  4. Bake for 20-25 minutes, until the edges are browned. Cover the edges of the pie with foil and bake for an additional 5-15 minutes, until the top crust is light golden and semi-firm to the touch. (It will not fully firm up until after cooling.)

  5. Remove the pie from the oven and cool completely before cutting or removing from the pan.
