1 box yellow cake mix
1/2 cup unsalted butter, melted
1 large egg
8 oz cream cheese, softened
2 cups pumpkin puree
3 cups powdered sugar
1 tsp vanilla extract
1 tsp pumpkin pie spice
Preheat your oven to 350°F (175°C). Grease a 9×13 inch baking dish.
In a bowl, combine the yellow cake mix, melted butter, and egg. Mix until just combined; it will be thick.
Press the cake mixture evenly into the bottom of the prepared baking dish. Set aside.
In another bowl, beat the softened cream cheese until smooth. Gradually add in the pumpkin puree, powdered sugar, vanilla extract, and pumpkin pie spice. Mix until smooth and combined.
Pour the pumpkin mixture over the cake base, spreading evenly. Don’t worry if it looks a little uneven; it will bake beautifully.
Place in the preheated oven and bake for 40-50 minutes. The edges should be set, but the center should remain gooey.
Remove from the oven and allow it to cool for at least 10-15 minutes before serving. Serve warm or at room temperature for the best texture.
Garnish with whipped cream or a sprinkle of cinnamon if desired and enjoy your pumpkin gooey butter cake!
