In a deep pan, brown the stick of butter. Once the butter is completely browned, stir in the light brown sugar until it is completely incorporated. Add the peaches and cover in the butter/sugar mixture. Keep cooking on high (or as high as you need with your stove to keep it a good bubbly mixture) to cook down the peaches. When the sugar and peaches appear to be incorporated well (after about 5 minutes), add the vanilla, salt and bourbon. Cook for another 10 minutes or so until the entire mixture is a bit thicker and a taste let’s you know it is all melded together.
Mix the dry ingredients together in a mixing bowl. In another mixing bowl, mix the egg and whipping cream together until incorporated. Slowly add the dry ingredients and mix each addition together until batter is formed.
Assemble the cobbler: - 1 stick of butter
In another pan, brown another stick of butter. Once browned, pour into the baking dish. Add the batter on top of the butter. Do not stir. Spoon the peach mixture on top of the batter and do not stir.
Place the cobbler in a 9x13 baking dish and place in the oven at 375 for 20 minutes. Remove when top is golden brown and a toothpick inserted into the cake parts come out clean. You may need to adjust cooking time based on your dish and how your oven cooks. I used a ceramic Le Cruset baking dish so if yours is metal, smaller or larger you will need to reduce heat and cook longer or shorter depending on your choice.
