When lip-smacking, chin-dripping peaches are in season, there is nothing like a wonderfully tasty cobbler. Serve it warm, with a scoop of vanilla ice cream.
Butter the bottom and sides of a 6-cup round soufflé dish. Arrange peaches, with any accumulated juices, in dish.
In a medium bowl, whisk together baking mix, 1/3 cup brown sugar and nutmeg. Whisk in milk just until moistened and a few lumps remain. Pour evenly over peaches.
Add 1-1/2 cups hot water to the inner pot and place the steam rack in the pot. Place a crisscross foil sling on the rack and place the souffle dish in the sling.
Close and lock the lid and turn the steam release handle to Sealing. Set your Instant Pot to Pressure Cook on High for 20 minutes.
When the cooking time is done, press Cancel and let stand, covered, for 10 minutes, then turn the steam release handle to Venting. When the float valve drops down, remove the lid and foil. A tester inserted in the center of the cobbler should come out clean. (If more cooking time is needed, continue pressure cooking on High for 2 minutes, then quickly release the pressure.)
Meanwhile, preheat broiler with the rack about 7 inches from the heat.
Using the foil sling, remove dish from the pot. Sprinkle with the remaining brown sugar. Broil for about 5 minutes or until topping is browned. Let cool on rack and serve warm or at room temperature.
Notes
To quickly peel peaches, fill the inner pot halfway with water. Set your Instant Pot to sauté on Normal. When the water is boiling, use tongs to dunk each peach in the water for 10 to 20 seconds or until the skin starts to split. Quickly plunge peach in a bowl of ice water. Use your fingers to peel the skin off the peaches. Reserve 1-1/2 cups water in the pot for step 3 and discard the remainder.
You can use 2-1/2 cups frozen sliced peaches, thawed, in place of fresh. Combine the peaches with 3 tbsp orange juice or water before adding them to the souffle dish.
