Stir all cobbler ingredients together and place in the bottom of a cast-iron skillet. In a medium bowl, mix together all streusel toppings. Crumble streusel over the peach mixture. Cover skillet and heat over medium heat for 15-25 minutes, until the peaches reach your preferred tenderness and the streusel topping has set.
Serve topped with coconut milk ice cream and a sprinkling of fresh blueberries.
