Preheat the oven to 350°F (180°C).
Slice the peaches and add them to a mixing bowl with the coconut sugar, lemon juice, vanilla, and cornstarch. Mix well to coat the fruit, then transfer to a baking dish.
2 pounds yellow peaches, ¼ cup coconut sugar, 1 tablespoon lemon juice, 1 teaspoon vanilla extract, 2 tablespoons cornstarch
In another mixing bowl, whisk the flour, sugar, and baking powder together. Make a well in the middle and add the milk, butter, vanilla, and optional spices. Whisk until just combined but make sure not to over-mix.
1 cup all-purpose white flour, ½ cup sugar, 2 teaspoons baking powder, ¾ cup plant based milk, ¼ cup melted vegan butter, 1 teaspoon vanilla extract, ½ teaspoon nutmeg or pumpkin pie spice
Pour the batter topping over the fruit. Bake for 50-55 minutes, or until the topping is golden and the cobbler is bubbling around the edges. Cool for at least 20 minutes before serving.
Leftovers will keep for a few days, covered, in the fridge and can be frozen for up to 3 months.
