Step-by-Step Instructions
Prepare the Baking Environment
Preheat oven to 350°F (175°C) and grease a 9×13-inch baking dish thoroughly to prevent sticking.
Create the Base Layer
In a medium bowl, combine yellow cake mix (reserving 1 cup for topping), egg, and melted butter. Mix until combined, then press mixture evenly into bottom of prepared baking dish to form solid foundation.
Prepare the Pumpkin Filling
In a large bowl, whisk together pumpkin puree, eggs, both sugars, milk, vanilla extract, and all spices until smooth and well combined. The mixture should be free of lumps and uniform in color.
Assemble the Middle Layer
Pour pumpkin filling over the pressed cake base, spreading evenly to cover completely.
Make the Crumble Topping
In separate bowl, combine reserved cake mix, brown sugar, and cinnamon. Add cold cubed butter and use pastry cutter or fingers to mix until mixture becomes crumbly with various sized pieces.
Complete the Assembly
Sprinkle crumble topping evenly over pumpkin layer, distributing to ensure uniform coverage.
Bake to Gooey Perfection
Bake for 40-45 minutes until edges are set and center remains slightly gooey. Avoid overbaking to maintain the signature texture.
Cool Before Serving
Let cake cool for 20 minutes before serving to allow layers to set while maintaining warm serving temperature.
