Preheat the oven to 400°F and grease a 9 inch round tin or 9×13-inch baking dish (the beauty of crumbles is their flexibility!) with butter or coconut oil.
Layer the sliced fruit into the bottom of the baking dish and lightly toss with the lemon juice.
In a medium bowl, mix the flour, sugar, cinnamon, cardamom, baking soda, and salt. Add the butter or coconut oil and vanilla and combine until the mixture forms a crumbly dough. Sprinkle over the peaches and bake for 30 minutes, or until the mixture is just lightly browned on top and the fruit is juicy.
Serve warm with vanilla ice cream.
