For the crust:
Preheat the oven to 200 C.
In a medium bowl, combine the flour, baking powder, salt, and sugar.
In another small bowl, combine the almond milk, butter, water, and lemon juice.
Pour the milk mixture into the flour mixture. Stir until combined.
Divide the dough in two.
Roll out one half of the dough on a lightly floured surface with a floured rolling pin, into a circle.
Transfer the circle to the pie pan.
For the filling:
In a large bowl, add the sliced peaches. Add the rest of the peach filling ingredients to the bowl and mix to incorporate. Set aside.
Make the top crumble by mixing the remaining dough with topping ingredients, and add the mixture to the meat grinder.
Cover the pie crust bottom with the peach filling and top with crumbled mixture.
Bake for about 25 minutes or until the edges are golden.
