How to Make the Best Lemon Dump Cake (Step-by-Step)
- Preheat the oven : Set it to 350°F (175°C). While the oven heats up, gather your ingredients.
- Prepare the lemon mixture : In a large mixing bowl, combine the yellow cake mix, lemon zest, and crushed pineapple. Stir gently to ensure everything is evenly distributed. The mixture should be slightly chunky but well-combined.
- Layer the batter : Pour the mixture evenly into a greased 9×13-inch baking dish. Use a spatula to spread it out, ensuring even coverage.
- Dot with butter : Cut the butter into small cubes and dot them evenly over the cake batter. This will help create the signature gooey topping.
- Pour condensed milk : Slowly pour the sweetened condensed milk over the top of the butter. Be careful not to mix it in; you want it to form a distinct layer.

- Bake to perfection : Place the baking dish in the center of the oven and bake for 30 minutes, or until the top is golden and bubbly. The edges should be slightly caramelized.
- Cool and serve : Let the cake cool for at least 10 minutes before serving. This allows the layers to set and creates the perfect gooey texture.
🚨 Pro Tip : Let the cake cool slightly before serving for the best texture. If you prefer a warmer, gooier cake, serve it immediately after removing from the oven.
