Cooking time






  • For the tart crust:
  • 6 Tbsp butter, melted

  • 2 cups almond flour

  • 1/3 cup erythritol sweetener

  • 1 tsp ground cinnamon

  • For the filling:
  • 3 cups thinly sliced Granny Smith apples, peeled and cored

  • 1/2 tsp lemon juice

  • 1/4 cup butter

  • 1/2 tsp ground cinnamon

  • 1/4 cup erythritol sweetener

  • For the topping:
  • 1 Tbsp erythritol sweetener

  • 1/4 tsp ground cinnamon


  • Preheat the oven to 375 degrees F.
  • In a medium bowl, add all ingredients for the crust. Stir to well combined and crumbly.
  • Press dough firmly into a 10″ spring-form pan. Create a rim about 1/2 inch-high up the sides of the pan, using your fingers or the back of a metal teaspoon. Bake in preheated for 5 minutes.
  • Combine sliced apples and lemon juice in another bowl. Stir well. Lay sliced apples evenly across the bottom of the crust in a circular pattern. Press the apples down lightly when done.
  • In a small bowl, combine butter, cinnamon and sweetener and microwave for 1 minute. Whisk until smooth and brush or spoon evenly over the top of the apples. Bake the tart for 30 minutes.
  • Remove the tart and gently press the apples down flat with the back of a spoon or spatula. Reduce the heat to 350 degrees (F) and bake the tart for more 20 minutes.
  • Once cooked, remove from the oven and set aside.
  • Combine the cinnamon and sweetener. Sprinkle over the top of the tart. Slice and serve.
