Preheat oven to 375F.
In a food processor, combine graham crackers, coconut sugar, and melted ghee.
Process until very fine and pinch together when sticks.
Press into the bottom of a 9.5 inch pie dish, ungreased.
Bake for 12 minutes, let cool for 30 minutes. Lower the oven heat to 350F.
While crust is cooling, in a large bowl whisk together eggs, lime juice, maple syrup, lime zest, and sifted coconut flour.
Pour into cooled crust and bake for 22-25 minutes or until center is no longer jiggly. It can wiggle a little, just not 'wet' looking.
Let cool on stove for 30 minutes, then place in fridge for at least 2 hours or overnight.
Add a layer of defrosted whipped topping and add lime slices, zest, and reddiwhip for topping.
