Preheat the oven to 350°F
Combine the dry crust ingredients in a bowl (everything except the oil and water)
Add the oil and gradually add the water, mixing until a dough forms – it should be tacky, but not sticky*
Oil a muffin pan and press the dough into the tins and up the sides to make ~4 pie crusts (or for a thicker crust, 3 pies), leaving some dough aside for the lattice; you can either eyeball it or evenly divide the dough into 5 pieces (4 pieces for the tins, 1 for the lattice)
Bake the crusts for 5 minutes
Peel and dice the apples to your liking, if you haven't already
In a bowl, mix the diced apples and rest of the filling ingredients together
Generously scoop the spiced apples into the crusts; it’ll look like a dome of apples but they’ll lose volume as they bake so no need to press or pack them down
Use the extra dough to make the lattice – take a small piece, roll it between your hands, then flatten and shape it to form a long, skinny rectangle, making 5 pieces per pie. If there isn’t enough dough, no big deal! You can leave it plain, drizzle some caramel, add a crumble topping (such as a Brown Sugar Oat Crumble, linked in the notes), or jazz it up by serving with whipped cream or ice cream
Assemble the lattice by evenly spacing out 3 pieces parallel to one another, lay 2 more perpendicularly on top of those, then gently weave them together
Bake for 15-20 minutes, removing when the edges of the crust start to gain some golden brown color
Cover each pie with a little tin foil blanket to prevent the tops from burning, then bake for an additional 7-15 minutes, or until the filling is bubbly or apples are soft (piercing with a fork or toothpick to check) but not applesauce soft*
Let cool before removing the pies from the pan, then store in an airtight container at room temperature (or the fridge to last longer) and pop them in the microwave for ~10-15 seconds to warm before serving
