Peel apples if preferred, then core and chop them. We dice the apples for a more chunky and bite-sized texture. If you want a softer texture you can slice the apple thinly.
In a bowl, stir together the chopped apples, granulated sugar, lemon juice and cinnamon.
In a large mixing bowl, add the flour, oats, nuts, vegan butter and brown sugar. Using a pastry cutter, a fork, or your hands, combine until you have a rough mixture with no loose flour. It's ok to have some small chunks of butter in the crisp mixture.
In a 7 x 11 inch (18 x 28 cm) or 9 inch (23cm) square baking dish, spread out the apples and then sprinkle the crisp mixture on top.
Bake at 350℉ / 180℃ for 40-50 minutes, until the top is crisp and golden and the apple mixture is bubbling.
Serve warm and enjoy, with or without a scoop of vegan ice cream.
Notes
Apple tipsChoose an apple suitable for baking that won't go completely mushy when cooked. We used Granny Smith apples here. Golden Delicious, Honeycrisp, Braeburn or Fuji are other crisp varieties you could use.You can even use a combination of tart apples and sweet apples. If just using sweeter apples, you may wish to reduce the sugar in the filling, depending on your preference.Measuring flourFor best results use a scale to weigh your ingredients. If not, use the spoon and level method to measure flour in cups.If your crumble mixture seems too dry and has a very sandy texture or loose flour, you may have overmeasured the flour. Rub in some extra vegan butter until you have a more crumbly and moist texture.
