In a food processor, add the flour, sugar, and salt.
Cut the vegan butter into chunks, drop them into the food processor over the flour, and then add small scoops of the coconut oil.
Pulse the food processor until the vegan butter and coconut oil have been evenly distributed and the mixture resembles sand.
With the processor running, pour the cold water through the top of the processor and let it run until the dough comes together in a ball.
If the dough is still sticky, turn it out onto a floured surface and knead a few times.
Now, you can chill and use it later after wrapping it in parchment paper.
Or you can now roll it out on the floured surface to 1/8 inch thick and blind bake for another recipe, or fill and bake.
For blind baking, I recommend 350 degrees(F) for 15-17 minutes or until golden brown.
If you plan to use it for a baked pie, you can follow the instructions for that pie from this point.
