Easy 3-Ingredient Peach Dump Cake (In A Cast Iron Skillet)

It's bubbly, filled with juicy peaches, and made with my favorite fluffy yellow cake mix. But no one needs to know that. The sprinkle of earthy cinnamon on top of the cake mix completely elevates this simple dessert into a quick family favorite. My daughter and husband fight about what the best way to serve it is: drizzled with salted caramel sauce or with a scoop of vanilla ice cream. The truth is, they're both right.

This is one of my go-to dessert recipes because it's effortless, easy to switch up, and perfect for all types of occasions.

Simple ingredients: You need canned peach slices, a box of cake mix, butter, and a sprinkle of cinnamon. That's it.

Great for every occasion: We love it for weeknight family dinners, potlucks, dinner parties, and just about every event.

Beginner-friendly: No fancy techniques or ingredients, just dump the ingredients into the skillet!

Versatile: Swap the cake mix and fruit filling for a new version of this dump cake next time.

This juicy peach dump cake is proof that a stick of butter can go a long way. The measurements for the following ingredients are in the recipe card at the bottom of the post.

• Canned peaches: Save the syrup. Fresh and frozen peaches work too.
• Box of yellow cake mix: Use your favorite brand.
• Unsalted butter: You can also use salted butter.
• Ground cinnamon: Adds cozy warmth. Don't swap it for ground nutmeg.

This golden peach dump cake with a layer of tender yellow cake on top is one of the easiest desserts you can make this summer. Scroll to the bottom of the post for a printable recipe card.

Step 1: Pour the peaches and reserved ½ cup syrup into the prepared skillet and spread into an even layer. Sprinkle the dry cake mix evenly over the top, fully covering the peaches, do not stir. If using, dust cinnamon over the cake mix.

Step 2: Drizzle the melted butter slowly and evenly over the cake mix, covering as much of the surface as possible. Bake for 45–50 minutes, until the top is deep golden brown and the edges are bubbling. Remove from the oven and let rest for 10–15 minutes before serving. Top with vanilla ice cream or whipped cream.

Switching things up with seasonal fruit or a different box mix can add a little extra flavor depending on what you have at home. Here are some of my favorite twists:

Swap the box mix: White cake mix, spice cake mix, or a box of vanilla cake mix gives great flavor to this cake. I particularly love the spice cake mix variation in fall.

Blueberry dump cake: Swap the canned peaches for fresh blueberries tossed in lemon juice and then lightly dusted in flour.

Use fresh fruit: Chopped pineapple, apricots, strawberries, blackberries, and even raspberries are great alternatives to peaches.

Chocolate cherry dump cake: Use chocolate cake mix and swap the filling for fresh, pitted cherries for a black forest-inspired dump cake.

​This buttery peach dump cake with hints of cinnamon is an easy recipe to pull off when you don't want to spend all day in the kitchen. Here are our favorite ways to enjoy it:

• With a big scoop of vanilla ice cream or whipped cream.
• Drizzled with caramel for a caramel peach cobbler dump cake. This is my favorite!
• Prepped for a dinner party along with 5-Ingredient Chocolate Mousse Cups and No-Bake Tiramisu Cheesecake Cups.
• Made for potlucks along with No-Bake Pink Lemonade Pie and Oreo Fluff Salad.

​This delicious treat is best straight out of the oven, but here's how to store leftover peach dump cake for later:

Fridge

Covered with plastic wrap for up to 3-4 days. You can also store it in an airtight container. Keep it away from strong-smelling foods like onions to prevent the transfer of odors.

To Reheat It

To reheat it: Place it in the oven at 300F for 20-30 minutes. You can also heat it in the air fryer or in the microwave in 20-second increments until warm.

These simple tips and tricks will help you nail any dump cake flavor you ever want to make. Here's what to do for best results:

Use the right pan: If you're not using a skillet, stainless steel baking pans are always best because they heat up quickly and distribute heat evenly. Ceramic ones are second best. Avoid glass ones at all costs because they take too long to heat up and often burn whatever's in the bottom before the rest of the cake is done.

Right skillet size: A 10-inch cast iron skillet works best. A smaller skillet may overflow, and a larger one will spread too thin.

Quick clean-up: Line the bottom of the skillet with parchment paper or aluminum foil before adding the peach filling and cake mix to prevent sticking.

Add-ins: Mix ½ cup chopped pecans, sliced walnuts, dried cranberries, or shredded coconut into the canned peach mixture for extra flavor and texture.

Assemble in the right order: Layer the ingredients, such as peaches on bottom, dry cake mix on top, butter last. Do not stir. Pour melted butter evenly over the cake mix to help it bake into a golden, crisp topping. Any dry spots may stay powdery, and it is completely safe to eat.

No peach pie filling: Fruit pie filling can have excess sugary and make this dessert overly sweet because the cake box mix is already sweetened, so I prefer sticking to canned peaches instead.

​Here's what other home cooks with a sweet tooth for peach desserts are asking about this recipe:

No. The butter needs to be melted so it can cover the cake mix and help "cook" the cake.

No. Peach dump cake and peach crisp are different desserts. Both are effortless bakes, but peach crisp has a crumbly, oat-flour topping that "crisps" up in the oven.

Of course! Mixing 1 teaspoon vanilla extract into the peach mixture gives it great flavor.
