This easy Crockpot Pineapple Upside-Down Cake is made with a boxed yellow cake mix, canned pineapple rings, brown sugar, butter, and maraschino cherries. Pour the batter over the fruit, cook the cake in a 6-quart slow cooker on HIGH for 2 to 2 1/2 hours, then let it rest for 10 to 15 minutes before turning it onto a plate.
The result is a soft, moist cake with buttery caramelized brown sugar, juicy pineapple, and little bursts of cherry in every slice. Using reserved pineapple juice in the batter gives the cake extra fruit flavor while the slow cooker keeps the crumb wonderfully tender.
Jump to RecipeWhy You’ll Love This Recipe
This crockpot dessert delivers the classic look of pineapple upside-down cake without requiring a hot oven. The slow cooker does the baking while the pineapple, cherries, butter, and brown sugar create a glossy topping that settles over the cake when it is inverted.
It is especially useful when you are preparing a large meal and need the oven for another dish. Prep takes only 15 to 20 minutes, and the recipe produces 8 to 10 generous servings for family dinners, potlucks, birthdays, or casual weekend gatherings.
The cake mix keeps the process simple, but the finished dessert does not taste plain. Reserved pineapple juice replaces part of the usual cake-mix liquid, adding a bright fruity note to the buttery yellow crumb.

Ingredients You’ll Need
Set out the ingredients before you begin so the topping and batter come together quickly. A 6-quart slow cooker, preferably oval, gives the cake enough surface area for the pineapple rings and an even layer of batter.
- Butter and brown sugar: Melted unsalted butter coats the bottom, while packed light brown sugar forms the caramel-style topping.
- Pineapple and cherries: Use one 20-ounce can of pineapple rings and 10 to 12 drained maraschino cherries. Reserve the pineapple juice for the batter.
- Cake batter: Combine one 15.25-ounce box of yellow cake mix with three large eggs, 1/2 cup vegetable oil, and one cup of pineapple juice topped off with water.
- Pan preparation: Lightly grease the slow cooker and add a round of parchment to help the cake release cleanly.
Drain the pineapple and cherries thoroughly before arranging them. Extra syrup or juice can make the brown-sugar layer watery, create excess steam, and delay the point at which the cake is fully set.

How to Make It Step-by-Step
Step 1: Lightly grease the inside of a 6-quart slow cooker, paying attention to the bottom and lower sides. Set a round of parchment in the base and grease the parchment lightly so the delicate fruit topping has a better chance of releasing in one piece.
Step 2: Pour 1/2 cup of melted unsalted butter across the bottom of the crock. Sprinkle 1 cup of packed light brown sugar evenly over the butter rather than leaving thick piles in one area, since an even layer helps the topping cook consistently.
Step 3: Arrange the drained pineapple rings over the brown sugar. Put one maraschino cherry in the center of each ring, and cut extra rings in half if necessary to fill gaps around the edges of the slow cooker.
Step 4: Measure the reserved pineapple juice and add enough water to make exactly 1 cup of liquid. In a separate bowl, combine the yellow cake mix, three eggs, 1/2 cup vegetable oil, and the juice mixture.
Step 5: Beat the cake batter just until smooth, usually 1 to 2 minutes. Avoid overmixing, because a gentle mix helps preserve a tender crumb rather than making the cake heavier than necessary.
Step 6: Pour the batter slowly over the pineapple layer. Spread it carefully with a spatula or the back of a spoon, taking care not to shift the rings or cherries underneath.
Step 7: Cover the slow cooker and cook on HIGH for 2 to 2 1/2 hours. If you want to reduce condensation on the cake surface, place a clean kitchen towel under the lid, keep it away from the heating element, and make sure it does not hang down the sides.
Step 8: Start checking near the early end of the cooking range because slow cookers do not all heat at the same rate. The cake is done when the center is set and a toothpick inserted into the cake comes out with only a few moist crumbs.
Step 9: Turn off the slow cooker and let the cake rest for 10 to 15 minutes. Run a knife around the edge, place a serving plate over the crock, and carefully invert the cake in one confident motion.
Step 10: Lift away the crock and parchment, allowing any topping that remains behind to be spooned back onto the cake. Slice while warm or at room temperature, and serve each piece with plenty of pineapple and cherry topping.
Pro Tips for the Best Crockpot Cake
The brief resting period is important. It lets the buttery brown-sugar topping settle and gives the cake time to firm slightly, making the inversion less messy and reducing the chance of a broken center.
Do not open the lid repeatedly while the cake cooks. Each release of steam can lower the temperature and extend the cooking time, so check only when the cake is approaching the early end of the recommended range.
The clean towel under the lid helps absorb condensation, but it must be used safely. Keep the towel away from the heating element and make sure no fabric hangs over the sides where it could become unsafe.
Because the slow cooker is enclosed, this cake will be softer and moister than a cake baked in a conventional oven. That texture is part of its appeal, particularly when the warm fruit topping melts into the tender crumb.
Use a serving plate with a slight rim if possible. The melted butter, brown sugar, and pineapple juices create a delicious sauce, and a rim helps keep those flavorful juices around the cake instead of running onto the counter.

Serving Suggestions
Serve slices warm, at room temperature, or chilled from the refrigerator. The cake is flavorful on its own, but a spoonful of softly whipped cream or a small scoop of vanilla ice cream pairs beautifully with the warm pineapple and caramel-like topping.
For a pretty presentation, place one pineapple ring and cherry on each slice when possible. If the rings overlap in the crock, cut the cake into portions that include a combination of pineapple pieces and topping.
This dessert is sweet and fruity enough for a celebration but easy enough for a weeknight treat. It also travels well once cooled, provided it is kept level so the glossy topping stays in place.
If you are planning a relaxed party menu, balance this dessert with a snack such as our easy cheeseburger dip before the meal.
Storage and Reheating
Let leftover cake cool completely, then cover it tightly and refrigerate it. The fruit topping contains moisture, so refrigeration is the best choice for maintaining quality when the cake will not be eaten the same day.
Enjoy refrigerated slices cold, or warm individual servings gently until just heated through. Avoid overheating, which can make the cake rubbery and cause the fruit topping to separate.
When serving leftovers, use a broad spatula to support the moist cake from underneath. A little extra topping spooned over each slice will refresh its glossy finish and keep every bite juicy.
Common Questions
Can I cook it on LOW? Some versions use LOW for approximately 3 1/2 to 4 hours. Since slow cookers vary, watch for a set center and use the toothpick test rather than relying only on the clock.
Why use pineapple juice in the batter? The reserved juice can replace some or all of the water typically listed on the cake-mix package. Here, it is combined with water to make one cup total, adding pineapple flavor while keeping the batter properly hydrated.
Can I use another cake mix size? The specified formula is designed for a 15.25-ounce box. If your box is a different size, follow its package quantities for eggs and liquid rather than automatically using the amounts listed here.
Why is my cake very wet on top? Condensation, poorly drained fruit, or opening the lid often can add moisture. Drain the pineapple and cherries well, use the towel-under-the-lid method safely, and allow the finished cake to rest before inverting.

Ingredients
Method
- Lightly grease the inside of a 6-quart slow cooker, preferably an oval model. Place a round of parchment in the bottom and grease it lightly for easier removal.
- Pour the melted butter over the bottom of the slow cooker and sprinkle the packed brown sugar evenly over it. Arrange the drained pineapple rings over the sugar, placing one maraschino cherry in the center of each ring.
- If needed, cut extra pineapple rings in half and use the pieces to fill open spaces. In a bowl, combine the cake mix, eggs, oil, and one cup of pineapple juice mixed with water.
- Beat the batter just until smooth, generally 1 to 2 minutes, and do not overmix. Gently pour it over the pineapple layer, then spread it evenly without disturbing the fruit.
- Cover the slow cooker and cook on HIGH for 2 to 2 1/2 hours. For a less-wet surface, place a clean kitchen towel beneath the lid, keeping it away from the heating element and preventing it from hanging down the sides.
- Begin checking near the early end of the cooking range because slow cookers vary. The cake is ready when the center is set and a toothpick inserted into the cake comes out with only a few moist crumbs.
- Turn off the slow cooker and let the cake stand for 10 to 15 minutes. Run a knife around the edge, place a serving plate over the crock, and carefully invert the cake onto the plate.
Notes
Final Thoughts
