Step 1: Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking dish.
Step 2: In a medium bowl, beat the softened cream cheese and powdered sugar together until smooth and creamy. Set aside.
Step 3: Evenly sprinkle the dry lemon cake mix over the bottom of the prepared baking dish.
Step 4: Drop spoonfuls of the cream cheese mixture over the cake mix layer. Don’t worry about spreading it out; it will spread as it bakes.
Step 5: Pour the melted butter evenly over the top of the cake mix and cream cheese layers.
Step 6: Spoon dollops of lemon curd over the top, spreading it slightly with a spatula for even distribution.
Step 7: In a separate bowl, whisk together the eggs and vanilla extract. Pour this mixture evenly over the entire cake.
Step 8: Place the baking dish in the preheated oven and bake for 35-40 minutes, or until the top is golden and a toothpick inserted into the center comes out clean.
Step 9: Allow the dump cake to cool for about 10-15 minutes before serving. Optionally, garnish with fresh lemon zest for added flavor and presentation. Serve warm or at room temperature, with whipped cream or ice cream if desired.
