In a large mixing bowl, whisk together the eggs, brown sugar and granulated sugar until well combined. Stir in the pumpkin puree, heavy cream, salt and spices and mix until smooth. Pour into the bottom of the prepared baking dish.

For the cobbler topping, whisk together the flour, sugar, baking powder, salt and cinnamon until no lumps remain. Cut the butter into the mixture with a fork or your hands until it has a coarse, crumbly texture. Gently mix in the oats. Add the beaten egg and buttermilk, then stir until the mix is just combined and moistened. Drop the mixture by large spoonfuls over the pumpkin. Sprinkle over the chopped, toasted pecans.
1 cup all purpose flour, 3 Tablespoons granulated sugar, 1 ½ teaspoons baking powder, ½ teaspoon kosher salt, ½ teaspoon ground cinnamon, 4 Tablespoons unsalted butter, 1 egg, ¼ cup buttermilk, ¾ cup pecans, ¼ cup rolled oats
Bake the cobbler until the top is golden brown and the custard has set, about 45 to 50 minutes. Let rest for at least 10 minutes before serving.
