Preheat the oven to 350°F. Lightly grease an 8x8-inch baking dish or similar-sized oven-safe dish.

In a medium bowl, combine the mixed berries, honey, cornstarch, and 1 teaspoon vanilla extract. Stir to coat evenly, then pour the mixture into the prepared baking dish.

In a separate bowl, whisk together the almond flour, coconut flour, coconut palm sugar, baking powder, and salt. In another small bowl, whisk the egg, melted butter, and remaining 1 teaspoon vanilla extract.

Pour the wet mixture into the dry ingredients and stir until a soft dough forms.

Drop spoonfuls of the topping evenly over the berry mixture. Gently spread with the back of a spoon, leaving a few gaps for the berries to bubble through.

Place the dish in the oven and bake for 30–35 minutes, or until the topping is golden brown and the berries are bubbly.

Cool and serve: Let the cobbler rest for 10–15 minutes before serving to allow the filling to thicken. Serve warm with whipped cream or vanilla ice cream, if desired.
