My sister serves this at every pool party and it vanishes instantly. Only 3 ingredients for the ultimate summer treat!

This slow cooker 3-ingredient mai tai dump cake is my secret weapon for summer get-togethers. My sister actually started the tradition—she makes it for every pool party, and it disappears before anyone even thinks about dessert plates. It’s a lazy-day mash-up of a tiki bar mai tai and a classic dump cake: canned pineapple for juicy sweetness, boxed cake mix for that golden, bubbly top, and an almond-spiked rum syrup that soaks into every bite. You literally dump, drizzle, and walk away, which makes it perfect for busy weeks when you still want something fun and a little bit tropical without heating up the whole kitchen.

Scoop the warm mai tai dump cake straight from the slow cooker into bowls. It’s amazing on its own, but a scoop of vanilla ice cream or a dollop of whipped cream makes it feel extra special and helps balance the rum and almond flavors. For a pool-party spread, I like to set it next to a bowl of fresh cherries or sliced strawberries for a pop of color. It also pairs really well with iced tea, sparkling water with lime, or your favorite fruity mocktail or cocktail—especially anything with pineapple or orange.

Servings: 8-10

1 (20-ounce) can crushed pineapple in juice, undrained

Lightly coat the inside of a 4- to 6-quart slow cooker with nonstick cooking spray or a thin layer of butter to help prevent sticking and make cleanup easier.

Pour the entire can of crushed pineapple with all of its juice into the bottom of the slow cooker. Use a spoon to spread it into an even layer so the cake cooks evenly and the pineapple chunks are distributed throughout.

Sprinkle the dry yellow cake mix evenly over the pineapple layer. Do not stir. Gently shake the slow cooker insert or pat the top with clean hands to level the dry mix so there are no big mounds.

Slowly drizzle the almond-flavored rum evenly over the dry cake mix, trying to moisten as much of the surface as possible. It’s okay if a few dry spots remain—those will turn into delicious, slightly crunchy, caramelized bits around the edges.

Cover the slow cooker with the lid and cook on HIGH for 2 to 3 hours, or on LOW for 4 to 5 hours. The cake is done when the top is mostly set, the edges are golden brown and bubbling, and the pineapple mixture is thick and syrupy around the sides.

Turn off the slow cooker and let the cake sit, covered, for 10 to 15 minutes to firm up slightly. This rest time helps the rum-infused almond syrup soak into the cake and makes scooping easier.

Serve the mai tai dump cake warm, scooping it straight from the slow cooker into bowls. Spoon some of the pineapple and syrup from the bottom over each serving for extra flavor. If you like, top with vanilla ice cream or whipped cream and enjoy immediately.

For a lighter version, you can swap half of the almond-flavored rum with pineapple juice or orange juice to keep the mai tai vibe while cutting back on alcohol. If you don’t have an almond-flavored rum, mix 3/4 cup white or dark rum with 1/4 cup almond syrup (like orgeat or coffee-shop almond syrup) to make up the 1 cup. For a kid-friendly, alcohol-free version, replace the rum entirely with a mix of pineapple juice and almond syrup; cook time stays the same. If you prefer a slightly less sweet dessert, use pineapple packed in its own juice instead of heavy syrup and choose a “less sugar” cake mix if available. For extra texture, sprinkle a handful of sliced almonds over the dry cake mix before adding the rum drizzle. Food safety tips: because this recipe uses alcohol, clearly label it if children or anyone avoiding alcohol will be present. The alcohol will not fully cook off in a slow cooker, so treat it as an alcoholic dessert. Always cook on the recommended setting until the center is set and bubbling at the edges to ensure the cake mix is fully cooked. Keep the slow cooker on WARM if serving over a longer party window (up to 2 hours), then turn it off and refrigerate leftovers in a covered container within 2 hours of cooking. Reheat leftovers thoroughly in the microwave or in the slow cooker on LOW until steaming before serving.
