Make crumble topping in a large mixing bowl. Combine the flour, light brown sugar and add the diced vegan butter. Using a pastry cutter, a fork, or your hands, combine until you have a crumbly mixture.
1 cup (125 g) all purpose flour, ⅔ cup (135 g) light brown sugar, ½ cup (110 g) vegan butter
Prepare peaches or nectarines. Peel if desired, then slice in half, remove pit and cut into slices.
4-5 large peaches or nectarines
Make peach filling directly in a 8 x 8 inch (20cm) baking dish, by stirring together sliced peaches, lemon juice, zest, spices and cornstarch.
1 lemon, 1 teaspoon cinnamon, ½ teaspoon ground ginger, 1 tablespoon cornstarch, ¼ teaspoon nutmeg
Scatter the crumble mixture evenly over the top of the peaches. No need to press the topping down.
Bake at 350℉ / 180℃ for around 40 minutes, until the top is golden brown and the peach mixture is bubbling.
Serve warm and enjoy, with a scoop of vegan vanilla ice cream!
