Aunt donna said this is the one to bring when you want people to ask for the recipe before they even finish chewing.

This coconut dump cake is the one I bring when I want people to ask for the recipe before they’ve even finished chewing. It’s inspired by the kind of thing an aunt like Donna would show up with at church potlucks and school bake sales—simple ingredients, almost no effort, and a buttery, golden, toasted-coconut top that looks gorgeous in a clear glass casserole dish. Everything gets “dumped” in the pan, no mixer needed, and the sweetened condensed milk melts into a creamy, almost custardy layer around the edges that makes everyone go back for seconds.

Serve this coconut dump cake warm or at room temperature, scooped straight from the glass casserole dish so everyone can see that toasty golden top. It pairs beautifully with a scoop of vanilla ice cream, a dollop of whipped cream, or even a drizzle of chocolate or caramel sauce if you want to make it extra special. For a lighter touch, serve smaller squares with fresh berries or pineapple on the side. It travels well, so it’s perfect for potlucks, game nights, and Sunday dinners—just set it on the counter and let folks help themselves.

Servings: 10-12

1 can (14 ounces) sweetened condensed milk

Preheat your oven to 350°F (175°C). Lightly grease a 9×13-inch clear glass casserole dish with nonstick spray or a thin layer of butter. This helps the edges get that nice creamy-caramelized finish without sticking.

In a medium bowl or large measuring cup, whisk together the sweetened condensed milk, coconut milk, salt, and vanilla extract until smooth and well combined. This is your creamy base that will bubble up around the cake and make those luscious edges.

Pour the milk mixture evenly into the prepared glass casserole dish. Sprinkle 1/2 cup of the sweetened shredded coconut over the top of the liquid, letting it float and spread out as evenly as you can.

Open the box of yellow cake mix and sprinkle the dry mix evenly over the entire surface of the dish. Try to cover all the wet spots, but don’t worry if there are a few small gaps; they’ll bake up just fine.

Slowly drizzle the melted butter over the dry cake mix, trying to moisten as much of the surface as possible. It’s okay if there are a few dry patches—those usually turn into lovely, crisp, golden bits.

Sprinkle the remaining 1/2 cup of sweetened shredded coconut over the top. This layer is what gives you that toasted, speckled, golden finish that looks so pretty through the sides of the clear glass dish.

Place the casserole dish on the middle rack of the preheated oven and bake for 35 to 45 minutes, or until the top is deeply golden brown, the coconut is toasted, and the edges are bubbling and creamy. The center should look set but still a little soft—more like a gooey bar than a firm cake.

Remove from the oven and let the dump cake rest on a cooling rack for at least 20 to 30 minutes. This helps the layers settle so you get that creamy edge and soft, spoonable center while still holding together when you serve.

Serve warm, scooped out with a large spoon or cut into squares right from the glass dish so everyone can see the toasty coconut top and creamy edges. Store any leftovers covered in the refrigerator for up to 3 days; rewarm gently in the oven or microwave before serving.
