Cut the butter into the flour, stach and sugar, mix until well combined. (I use my hands and squish the shortening and flour together until a crumbly mixture forms)
Add the egg yolk, milk and vinegar. Then mix until a firm dough forms. (It will seem to dry at first but just keep mixing it. I like to press it into the bottom of the bowl and sort of knead it like bread dough. A smooth dough will form.) Place the dough wrapped in plastic wrap in the fridge for ½ - 1 hour.
Pre heat oven to 425 F.
In a large mixing bowl mix the canned pumpkin with the sweetened condensed milk, egg and cinnamon.
On a lightly rice floured piece of parchment paper on your counter, roll out to dough until it's big enough to cover your pie pan. If the dough breaks or cracks just press it back together with your fingers.
Place the rolled out crust into the pie pan then trim the edges. Put the pie crust in the fridge for another 10 minutes , then use a fork and poke some holes into the bottom of the crust. Then fill with the gluten free pumpkin pie filling.
Cover the edges of crust with tin foil and Bake for 15 minutes. Then turn your oven down to 350 F. Bake for approximately another 40-45 minutes. Let cool completely before serving.
Note: Make sure it's the Pumpkin Puree and not Pumpkin Pie Filling. Some of the brands of canned pumpkin pie filling have wheat in them.
