Ingredients

• Peaches in syrup or sliced fresh peaches - I prefer the peaches in heavy syrup because of the juice and also the fact that they make this recipe so easy, but fresh peaches will also work and will taste great.
• Yellow cake mix - This recipe uses the dry cake mix only. You will not be mixing the cake batter.
• Butter - It doesn't matter whether you use salted or unsalted butter.
• Ground cinnamon optional
• Vanilla ice cream optional for serving

Substitutions & variations

You can use yellow cake mix, white cake mix, butter cake mix, or even butter pecan cake mix for this peach dump cake. Yellow cake mix gives the topping a classic buttery flavor, while white cake mix is a little lighter. Spice cake mix is another delicious option if you want a warm, fall-inspired dessert.

If you prefer fresh peaches, you can use peeled and sliced ripe peaches instead of canned peaches. Fresh peaches don't have the extra liquid and sweetness of canned peaches, so you will need to add a little sugar and peach juice or apple juice to keep the filling moist.

For extra flavor, a little vanilla extract or almond extract mixed into the peaches is an easy way to enhance the flavor.

You can also add chopped pecans or walnuts over the cake mix for a little crunch. The nuts will toast as the dump cake bakes and add a delicious nutty flavor to the buttery topping.

If you don't have a cast iron skillet, you can make this peach dump cake in a regular baking dish instead. A 9x13-inch baking dish works well for a full-size recipe, but you may need to adjust the baking time depending on the size and depth of your dish.

Serve this easy peach dump cake warm with a scoop of vanilla ice cream, whipped cream, or a drizzle of caramel sauce. The cold ice cream melts into the warm peaches and buttery cake topping, making an already delicious dessert even better.

Storing leftover peach dump cake

Cover and store at room temperature for up to 2 days.

For longer storage, transfer leftovers out of the cast iron skillet into an airtight container and store in the fridge for up to 5 days. Fruit left in cast iron can pick up a metallic taste and wear down the seasoning.

Warm individual servings in the microwave for 20 to 30 seconds, or rewarm in a 350°F oven until heated through.

You can also wrap cooled portions tightly in aluminum foil or plastic wrap and freeze for up to 3 months. Thaw overnight in the refrigerator.
