Before diving into the actual mixing and baking, take a moment to:

1. Set your oven to preheat at 350°F (175°C)
2. Gather all ingredients on your counter, allowing refrigerated items like cream cheese, butter, and eggs to come to room temperature
3. Prepare a 9×13-inch baking dish with a light coating of cooking spray or butter

Mixing the Cream Cheese Layer

1. This layer creates that irresistible tangy-sweet middle that makes this dessert so special:
2. In a mixing bowl, beat the softened cream cheese until it’s completely smooth and free of lumps
3. Gradually add your powdered sugar while continuing to mix
4. Once combined, blend in your eggs one at a time
5. Finally, stir in the lemon juice and zest, mixing until you have a silky, uniform consistency
6. Quick Tip: If your cream cheese still has a few small lumps, press the mixture through a sieve for perfectly smooth results!

Creating the Cake Layers

1. Now for the signature “dump cake” technique:
2. In a separate bowl, combine your dry cake mix with one beaten egg
3. Pour in the melted butter and stir until you have a crumbly, moist mixture
4. Take about two-thirds of this mixture and press it firmly into the bottom of your prepared baking dish, creating an even base layer
5. Pour your cream cheese mixture over this base, spreading it gently to the edges
6. Sprinkle the remaining cake mixture evenly over the top
7. Arrange thin slices of butter across the surface of the cake (this creates a beautifully golden, slightly crisp top)

Baking Your Creation

1. The transformation happens in the oven:
2. Bake at 350°F for 40-45 minutes, or until the edges are set and the top is golden brown
3. Look for slight browning on the crumble topping and a center that still has a gentle wobble when the pan is lightly shaken
4. Remove from the oven and place on a cooling rack

The Cooling Phase

1. Patience is key for the perfect texture:
2. Allow your cake to cool at room temperature for at least 30 minutes
3. For the best slicing results, refrigerate for a minimum of 2 hours before serving
4. As it cools, the layers will set and the flavors will deepen and meld together
