Description

This effortless dessert combines juicy frozen peaches with a buttery yellow cake mix topping for a warm, cobbler-style treat. Perfect for busy schedules, this one-pan recipe delivers a rustic bakery flavor with minimal preparation.


Ingredients

  • 6 cups frozen peach slices
  • 1/2 cup granulated white sugar
  • 1/2 cup packed brown sugar
  • 2 tablespoons cornstarch
  • 1 teaspoon ground cinnamon
  • 1/4 teaspoon ground nutmeg
  • 1 tablespoon fresh lemon juice
  • 1 package (15.25 oz) yellow cake mix
  • 1/2 cup unsalted butter, cold and thinly sliced
  • 1/2 cup chopped pecans


Instructions

  1. Prep the oven. Preheat your oven to 400°F and grease a 9×13-inch baking pan with non-stick cooking spray.
  2. Season the peaches. In a large bowl, combine the peaches, both sugars, cornstarch, cinnamon, nutmeg, and lemon juice, stirring well until coated.
  3. Spread the fruit. Spoon the peach mixture into the prepared pan and spread it into an even layer covering the bottom.
  4. Add cake mix. Sprinkle the dry yellow cake mix evenly over the peach layer, smoothing out any large mounds with a spoon.
  5. Arrange butter pats. Place thin, uniform pats of cold butter across the surface of the dry cake mix to cover as much area as possible.
  6. Add the pecans. Scatter the chopped pecans over the top of the butter and dry cake mix layer.
  7. Bake at high heat. Bake uncovered at 400°F for 30 minutes until the fruit juices are bubbling around the edges.
  8. Finish baking. Reduce the oven temperature to 350°F and bake for an additional 15 minutes before cooling briefly to set.

Notes

  • Keep the butter cold until the moment you slice it to ensure thin, even coverage over the dry cake mix.
  • If dry powdery patches remain on top, gently spread pools of melted butter over those areas midway through the baking process.
  • Use frozen berries or cherries mixed with the peaches if you want to experiment with different flavor profiles and colors.
  • Cover the assembled pan with foil and store in the refrigerator to bake fresh the next morning.
