A delightful twist on the classic pumpkin dessert squares, these bars feature a spiced crumble topping and a creamy pumpkin filling.
Preheat your oven to 350°F (175°C).
Always preheat your oven to ensure even baking.
In a mixing bowl, combine the yellow cake mix, melted butter, and one egg until a dough forms.
Mix until just combined to avoid overworking the dough.
Press the dough evenly into the bottom of a greased 13x9-inch baking dish.
Use the back of a spoon or your hands to press the dough evenly.
In another bowl, mix the pumpkin puree, two eggs, milk, cinnamon, and nutmeg until smooth.
Ensure the mixture is well blended for a creamy filling.
Pour the pumpkin mixture over the crust in the baking dish.
Spread the filling evenly for consistent layers.
In a separate bowl, combine the flour, brown sugar, cold butter, and cinnamon to create a crumbly topping.
Use your fingers or a fork to achieve a crumbly texture.
Sprinkle the crumble topping evenly over the pumpkin layer.
Distribute the topping evenly for a consistent crunch.
Bake in the preheated oven for 35-40 minutes, or until the topping is golden brown.
Check for doneness by inserting a toothpick into the center; it should come out clean.
Let the bars cool completely before slicing and serving.
Cooling allows the layers to set for cleaner slices.
