In a large mixing bowl, combine 1 1/2 cups (220 g) of rolled oats with 2 teaspoons of stevia.

Melt 1 tablespoon of butter and add it to the oats.

Mix in 1/4 cup (60 ml) of water and knead until the mixture holds together. If necessary, add more water, one tablespoon at a time.

Form the dough into a disk, wrap it in plastic wrap, and refrigerate it for at least 30 minutes.

Add the stevia, sliced apples and cook for about 5 minutes until they start to soften.

Stir in ½ cup (125 g) of unsweetened applesauce and 1 teaspoon of ground cinnamon. Mix well and remove from heat.

Preheat your oven to 375°F (190°C).

Roll out the chilled dough on a floured surface to fit your pie dish.

Place the rolled-out dough into a 9-inch (23 cm) pie dish.

Pour the apple mixture into the crust, spreading it out evenly.

Bake in the preheated oven for 45-50 minutes, or until the crust is golden brown, and the filling is bubbling.

Let the pie cool before slicing. It's delicious served warm with a scoop of vanilla ice cream or a dollop of whipped cream.
