Baking Dish - I've used my Emile Henry 1.8L baker which measures 9" x 11". If you want the cobbler to be more spread out and not risk it overflowing in the oven, use a 9" x 13" baking dish. I prefer it in a smaller dish because I love that it gives me a thicker sponge cake. I've baked this recipe many times in the smaller baking dish and it doesn't overflow, but it comes close. It's totally up to you! But I do recommend lining the base of your oven just in case - you don't want the sauce to leak and bake onto the base of your oven.
