Description

This easy peach upside-down cake uses a pantry-friendly white box mix to create a moist, golden crumb beneath a layer of caramelized, fresh peach wedges. It is the perfect stress-free dessert for warm family dinners and cozy weekend gatherings.


Ingredients

  • 6-8 ripe freestone peaches, sliced into thick wedges
  • 1 box white cake mix
  • 1/2 cup unsalted butter
  • 1/2 cup light brown sugar
  • 1/4 cup granulated sugar
  • 1 small package peach jello mix
  • 3 large eggs
  • 1 cup half-and-half
  • 1/3 cup vegetable oil
  • 1 teaspoon vanilla extract


Instructions

  1. Preheat the oven. Heat your oven to 350°F and place a heavy ten-inch cast iron skillet over medium heat to melt the butter.
  2. Caramelize the base. Whisk the brown and granulated sugars into the melted butter until a thick, sandy paste forms across the bottom of the pan.
  3. Prepare peach puree. Blend 2 cups of peach slices into a smooth puree and stir in the peach jello mix and vanilla extract.
  4. Arrange peach slices. Layer the remaining peach wedges in a decorative concentric circle pattern over the sugar and butter mixture in the skillet.
  5. Mix the batter. Combine the white cake mix, prepared peach puree, eggs, half-and-half, and oil in a stand mixer bowl until the batter is smooth and glossy.
  6. Bake the cake. Pour the batter over the peaches, spread evenly, and bake for 35 to 40 minutes or until a toothpick comes out clean.
  7. Rest and invert. Let the cake cool for exactly five minutes, then carefully invert it onto a serving platter to release the caramelized fruit top.

Notes

  • Always choose freestone peaches to ensure the pits remove cleanly and the slices hold their shape.
  • Ensure eggs and half-and-half are at room temperature to prevent the butter from seizing during mixing.
  • Use a timer to count the five-minute rest period strictly to prevent the caramel from either leaking or sticking to the pan.
  • If the cake edges brown too quickly, loosely tent the skillet with aluminum foil during the final ten minutes of baking.
