Preheat the oven to 350 degrees. Coat 4 ramekins with butter or cooking spray. Line a baking sheet with parchment paper.
Make the almond topping by combining the flour, brown sugar, baking powder, cinnamon, cardamom, salt, and diced cold butter in a small bowl; work the mixture with your fingers until crumbly and well combined. Add the sliced almonds and work them into the flour mixture; set aside until needed.
Make the filling by combining the peaches, raspberries, sugar, cornstarch, vanilla, and cinnamon in a bowl, then mix until the fruit is evenly coated.
Divide the mixture evenly into the ramekins.
Sprinkle the almond topping evenly over each dish.
Bake the mini crisps for 25-30 minutes or until the topping is golden brown and the fruit is tender.
Allow them to cool on a wire cooling rack for 10 minutes before serving as is or with vanilla ice cream. Enjoy.
