Get all the ingredients ready. Then, preheat the oven to 350 degrees F to ensure it’s nice and hot for baking.

Lightly grease the inside of a medium casserole dish with a bit of butter. I typically use a 7”x11″ dish for this recipe, but any similar-sized dish will work just fine.

In a large saucepan, combine the thawed peaches and 3/4 cup of white sugar. Gently stir them together over medium to medium-low heat until they come to a low boil. Let them simmer for about 6 to 7 minutes, stirring occasionally.

Once the peaches are simmered, remove the saucepan from the heat. Use a large slotted spoon to carefully lift the peaches out of the juice and place them into the prepared baking dish. Be sure to reserve the juice for later.

Measure out 1/2 cup of the reserved peach juice and pour it evenly over the peaches in the baking dish.

Now, it’s time to add the Jiffy golden yellow cake mix. Sprinkle the cake mix evenly over the peaches in the baking dish.

After adding the cake mix, sprinkle 1/4 cup of white sugar over the top.

Sprinkle 1/4 teaspoon of cinnamon evenly over everything in the baking dish.

To swirl everything together, gently use a butter knife to make swirls in the baking dish, combining some of the dry ingredients with the peach juices below.

Drizzle the top of the cobbler with 1/4 cup of melted butter, ensuring it’s evenly distributed.

If you’d like to add a twist, scatter 2 cups of fresh blueberries and 1⁄2 cup of chopped nuts over the top of the cobbler. This adds a burst of flavor and color!

Finally, bake the cobbler in the preheated oven at 350 degrees F for about 35 minutes, or until the top is golden brown and set. Once baked to perfection, remove it from the oven and let it cool slightly before serving. Enjoy your delicious Jiffy mix peach cobbler with a scoop of ice cream or a dollop of whipped cream!
