1 box yellow cake mix
1/2 cup unsalted butter, melted
1 egg
15 oz canned pumpkin puree
8 oz cream cheese, softened
3 cups powdered sugar
1 teaspoon vanilla extract
1 teaspoon pumpkin pie spice
Preheat your oven to 350°F (175°C). Prepare a 9×13 inch baking dish by greasing it or lining it with parchment paper.
In a large bowl, mix the yellow cake mix, melted butter, and egg until combined. Press this mixture into the bottom of the prepared baking dish.
In another bowl, beat the softened cream cheese until creamy. Gradually add the pumpkin puree, powdered sugar, vanilla extract, and pumpkin pie spice. Mix until well combined.
Pour the pumpkin filling over the crust, smoothing it out evenly.
Place the baking dish in the preheated oven and bake for about 40-45 minutes, or until the edges are set and the center has a slight jiggle.
Let it cool on a wire rack for at least 30 minutes, then cool completely in the refrigerator.
Cut into squares or slices, dust with powdered sugar, and serve with whipped cream or your favorite toppings.
