Can I use white box cake mix instead of yellow?

Yes, you can certainly use a white box cake mix instead of yellow for this recipe. The white mix has a slightly lighter flavor and a pale color, which allows the natural orange hue of the peach purée to shine through beautifully. The texture remains incredibly soft and tender regardless of which variety you choose.

How do I stop the peaches from sticking to the pan?

To prevent sticking, make sure your skillet is thoroughly coated with the melted butter before you sprinkle the sugar. Working quickly while the skillet is hot also helps the sugar dissolve into the butter rather than hardening on the iron. Always invert the cake within five minutes of taking it out of the oven before the caramel begins to cool and set.

Can I use fresh peaches instead of canned?

Fresh, ripe peaches are highly recommended for this recipe because they hold their shape much better and offer a brighter, more complex flavor. Canned peaches can be used in a pinch, but you must drain them thoroughly and pat them dry with paper towels to prevent excess moisture from making the cake soggy. If using canned, skip the purée step and use pre-made peach nectar instead.

Should I prepare the cake mix exactly as instructed on the box?

No, do not follow the standard instructions printed on the back of the cake mix box. Instead, use the specific liquid measurements and ingredients listed in our recipe card, including the fresh peach purée and half-and-half. This custom liquid ratio is designed to handle the heavy fruit topping without becoming dense or waterlogged.

When and how do I flip the cake?

Flip the cake exactly five minutes after removing it from the hot oven. Place your serving platter upside down over the skillet, use sturdy dry oven mitts to grip both sides, and turn them over in one confident, swift movement. Let the inverted skillet rest on the platter for ten seconds to allow gravity to release the fruit before lifting the pan.

How should I store any leftover cake?

Store any leftover cake in an airtight container in the refrigerator for up to three days. Because of the fresh fruit topping, leaving it at room temperature for too long can cause the caramelized peaches to spoil. When you are ready to enjoy a slice, warm it gently in the oven or microwave to soften the butter glaze.

Can I bake this recipe in a standard cake pan instead of cast iron?

Yes, you can bake this cake in a deep nine-inch round cake pan or a square baking dish if you do not own a cast iron skillet. Be sure to grease the sides of the pan thoroughly with nonstick spray or butter before adding the sugar and peaches. The baking time may vary slightly, so keep a close eye on the oven during the final ten minutes.

Cook Mode Prevent your screen from going dark

Instructions

Prepare the skillet. Preheat your oven to 350°F and melt the unsalted butter in a cast iron skillet over medium heat, then stir in the brown and granulated sugars until smooth.
Slice the fruit. Wash and slice the peaches into half-inch wedges, reserving two cups to pulse into a thick purée.
Purée the peaches. Pulse the reserved peach wedges in a food processor until smooth, then measure out one cup for the batter.
Flavor the base. Combine the peach purée with the peach jello mix and vanilla extract in a bowl, stirring until the gelatin dissolves.
Arrange the peaches. Lay the remaining peach slices in tight, overlapping circles over the butter-sugar mixture in the skillet.
Mix the batter. Combine the cake mix, flavored purée, eggs, half-and-half, and oil in a large bowl and beat on high for two minutes before pouring over the peaches.
Bake the cake. Bake for 35 to 40 minutes until a toothpick inserted into the center comes out clean.
Rest and invert. Let the skillet cool for five minutes, then carefully invert the cake onto a serving platter and rearrange any fruit that may have shifted.

Notes

Ensure the skillet is well-seasoned to prevent the caramelized fruit from sticking during the inversion process.
Use freestone peaches for easier prep as the pits release cleanly without tearing the fruit flesh.
Bring your eggs and half-and-half to room temperature before mixing to ensure a smooth, uniform cake batter.
Tent the top of the cake with aluminum foil if it starts browning too quickly to allow the center to finish baking properly.
