Step 1

Preheat the oven to 350 degrees Fahrenheit. Grease the bottom and sides of a 9" pie pan with coconut oil.

Step 2

Mix all the crust ingredients in a large bowl then transfer them to the prepared pie pan. Wet your hands lightly to prevent the crust from sticking to them then press the crust into the pan, making sure it is even on the sides and bottom.

Step 3

Bake the crust in the oven for 10 minutes. When you remove it from the oven, the crust will be puffed up and light golden brown. Use the back of a spoon to gently push the crust down so there is room for the filling.

Step 4

Bring an inch of water to a boil in a medium-sized pot. Add the purple yams and steam for 10 minutes, or until the yams can be pierced with a fork. Drain the yams then put them in a high-powered blender or food processor.

Step 5

Add the rest of the pie filling ingredients and blend on high until everything is smooth and creamy.

Step 6

Pour the pie filling into the baked pie shell and smooth out the top. Bake for 45 minutes, or until the pie has set but still has a little jiggle in the middle. Remove the pie from the oven and let it cool completely before serving it.
