Homemade Apple Pie with Oatmeal crumb topping. Easier to make than a double crust pie, this homemade apple pie has a delightful oatmeal crumb topping. Super delicious, especially served with a dollop of vanilla ice cream on top.
In a large bowl, mix the flour, cornstarch, and salt. Cube the butter and place it into a small bowl. In a measuring cup, add the vinegar and top with water to reach 1/3 cup. Put everything in the fridge for about 10 minutes.
To prepare the apples, you can use an apple slicer. Then, peel the slice and cut it into two to make it thinner.
In a food processor, combine the oats, flour, sugar, salt, cinnamon. Pulse a few times just to mix.
Place the dough on a lightly floured parchment paper and lightly dust the top with flour. Dust the rolling pin with flour, too. Flatten the dough a little, just to make it more workable.
Adjust the racks in the oven, one in the lower position, and one in the middle. Preheat the oven to 400°F (200°C).
