Cast Iron Peach Upside-Down Cake (Easy Southern Dessert)

Share to Social

Bake this Cast Iron Peach Upside-Down Cake with warm spices, buttery caramel, and juicy peaches for an easy Southern dessert perfect for fall gatherings.

Some desserts just seem to belong to a particular season.

As soon as the weather begins to cool, we find ourselves reaching for cinnamon instead of lemon, warm spices instead of bright citrus, and cozy desserts that make the whole house smell amazing. While fresh peaches are one of summer’s greatest gifts, canned peaches have earned a permanent place in our pantries because they make recipes like this possible all year long.

This Cast Iron Peach Upside-Down Cake is one of those desserts that feels equally at home on a Sunday dinner table, at a church potluck, or beside the pumpkin pie on Thanksgiving Day.

Fall Spices, Warm Peaches, Pure Fall Bliss!

It’s warm, buttery, gently spiced, and every bite tastes a little like peach cobbler and homemade cake all wrapped into one.

After the success of our recent Cast Iron Pineapple Upside-Down Cake, we couldn’t resist trying another version. This time we reached for peaches, added a sprinkle of apple pie spice, and used the reserved peach syrup in place of the water called for in the cake mix.

The result was everything we had hoped for.

Beautiful. Caramelized. Peaches.

The peaches caramelized beautifully in the brown sugar and butter, the cake stayed incredibly moist, and the warm spices transformed an ordinary cake mix into something that tasted completely homemade.

If you’re looking for a dessert that bridges the gap between late summer and the holiday season, you’ve just found it.

Here’s why we think you’ll love it:

• Easy cake mix shortcut
• Rich buttery caramel topping
• Warm cinnamon and spice in every bite
• Perfect for fall, Thanksgiving, and holiday gatherings
• Beautiful presentation with very little effort
• Delicious served warm with vanilla ice cream
• Oven, grill, and smoker friendly

Why You’ll Love Baking This in Cast Iron

If you’ve been following Backyard Texas Grill for a while, you’ve probably noticed we’ve become big fans of cast-iron desserts. There’s a good reason for that.

Cast iron distributes heat beautifully and holds that heat throughout the baking process. Instead of simply baking the cake, it slowly caramelizes the butter and brown sugar beneath the peaches, creating deeper flavor than a traditional cake pan.

The edges develop just enough color to add richness while the center stays wonderfully moist. It’s one of the reasons upside-down cakes feel so perfectly suited to cast iron.

Ingredients

You will find a full printable recipe card at the bottom of this post but here’s a quick glance at what you’re going to need to make this light and delicious peach upside-down cake in a cast-iron skillet.

For the Caramel Layer

• ½ cup (1 stick) butter
• 1 cup packed light brown sugar
• 1 teaspoon apple pie spice (or 1 teaspoon pumpkin pie spice or 1 teaspoon cinnamon plus ¼ teaspoon nutmeg)
• 1 (29-ounce) can sliced peaches in juice, drained well (reserve the juice)

For the Cake

• 1 (15.25-ounce) white cake mix
• 3 large eggs
• ½ cup melted butter
• Reserved peach juice (use in place of the water called for on the cake mix box)

How to Make Cast Iron Peach Upside-Down Cake

Here’s how you’re going to make this cake. It’s so easy and fun! (Your inner artist will get to come out and play.)

Step 1: Prepare the Caramel

Preheat your oven to 350°F.

Place a 10-inch cast-iron skillet over medium heat and melt the butter directly in the skillet.

Sprinkle the brown sugar evenly over the melted butter and stir gently until it begins to bubble.

Add the apple pie spice and stir until fragrant then remove the skillet from the heat.

Separate the peaches from their juice but reserve the use to use for the cake. Place the peaches on a plate with paper towels and do your best to pat them dry.

Arrange the peach slices in overlapping circles or a decorative pattern over the caramel. You can sprinkle with more cinnamon or apple pie spice if you like.

Step 2: Mix the Batter

In a large mixing bowl, combine the cake mix, eggs, melted butter, and the reserved peach juice.

Mix on low speed until incorporated, then beat on medium speed for about two minutes until smooth.

The batter will be thicker than a traditional cake batter because of the peach syrup. That’s perfectly normal.

Step 3: Assemble

Carefully spoon the batter over the peaches.

Use an offset spatula or the back of a spoon to gently spread the batter evenly all the way to the edges of the skillet. Try not to disturb the peach arrangement underneath.

Step 4: Bake

Bake for 40 to 50 minutes, checking for doneness around the 40-minute mark. (Mine baked for 45 minutes total before I pulled it out.)

A toothpick inserted into the center should come out clean or with just a few moist crumbs attached.

If the top begins browning faster than you’d like, loosely tent it with foil for the final few minutes of baking.

Step 5: Flip the Cake

Allow the cake to cool in the skillet for about 10 minutes. Run a thin knife around the edge of the cake.

Place a serving platter over the skillet and carefully invert the cake.

Leave the skillet upside down for about a minute before lifting it away. That little bit of patience helps every drop of caramel find its way back onto the cake instead of staying behind in the pan.

This would be a good time to explain that upside-down cakes that are baked in cast iron are often slightly darker in color than traditional upside-down cakes baked in ordinary pans. This is completely normal and good.

Serve and Enjoy!

This one slices beautifully! It’s tender, beautiful, and super easy to serve.

What to Expect from this Recipe

There are plenty of peach desserts to choose from, but this one offers the best of several favorites all in one skillet. You get the rich caramel topping of a classic pineapple upside-down cake, the cozy flavor of peach cobbler, and the convenience of a cake mix that comes together in just minutes.

The thing that surprised me most? This cake was feather-light. No, really. You don’t expect an upside-down cake to turn out as soft and light as a feather, but this one sure did. I think the peach juice did the trick, honestly. The added moisture in the peaches probably helped, too.

The top, instead of being crust-like, was most and beyond delicious. Again, the peach juice did its work, merging with the brown sugar. The result? A scruptuous cake with a lovely topping. Just perfect!

Tips for Success

Pat the peaches as dry as possible before arranging them in the skillet. Even canned peaches hold quite a bit of moisture, and removing a little of that liquid helps the caramel develop beautifully.

Don’t rush the flip. Letting the cake rest for about ten minutes gives the caramel time to settle while keeping it soft enough to release easily.

If your cake still looks slightly underdone at the 40-minute mark, don’t panic. Start checking around 45 minutes and bake until a toothpick inserted into the center comes out clean.

Finally, don’t be afraid to serve this cake warm with vanilla ice cream. The melting ice cream mingles with the buttery caramel and warm peaches in the best possible way.

Delicious Variations

One of the things I love most about this recipe is how easily you can customize it for different seasons and occasions.

While I chose a white cake mix because it lets the peaches shine, there are several delicious ways to make this recipe your own.

Butter Pecan Cake Mix

If you’re baking this cake for Thanksgiving or another fall gathering, this is probably the first variation I’d try. The buttery pecan flavor pairs beautifully with the peaches and warm spices, creating a dessert that feels even more special for the holidays.

Spice Cake Mix

For an even cozier version, swap the white cake mix for a spice cake mix. The cinnamon, nutmeg, and cloves complement the peaches perfectly and make the whole house smell amazing while the cake bakes.

Yellow Cake Mix

A yellow cake mix creates a richer, more traditional upside-down cake while still allowing the peaches to remain the star.

Change the Spice

Don’t have apple pie spice? No problem. Pumpkin pie spice works beautifully, or make your own blend with cinnamon, nutmeg, a pinch of cloves, and a little ginger.

Add Pecans

Scatter a handful of pecan halves over the peaches before adding the batter. As the cake bakes, the pecans toast in the buttery caramel and add wonderful crunch to every slice.

Storage

If you’re lucky enough to have leftovers, this cake keeps beautifully.

Cover it tightly and store it at room temperature for up to two days or refrigerate it for up to five days.

To serve, simply let slices come to room temperature or warm them in the microwave for 15 to 20 seconds. The caramel softens again, and the peaches become wonderfully tender.

What to Serve with Peach Upside-Down Cake

This cake is delicious all by itself, but it’s even better with a few simple additions.

A scoop of vanilla ice cream melting over the warm peaches is hard to beat.

Fresh whipped cream is another classic choice, especially if you’re serving the cake after Sunday dinner or taking it to a holiday gathering.

If you’re serving dessert after a backyard barbecue, pair it with sweet tea or freshly brewed coffee for the perfect ending to the meal.
