Preparation Steps

• Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
• In a large bowl, combine cake mix, water, oil, and eggs. Beat until smooth.
• Stir in pumpkin puree and pumpkin pie spice.
• Pour batter into prepared pan and bake for 30-35 minutes, or until a wooden skewer inserted into the center comes out clean.
• Let the cake cool completely.
• Poke holes all over the cake using a wooden skewer or the handle of a spoon.
• In a medium bowl, whip together heavy cream, powdered sugar, and vanilla extract until stiff peaks form.
• Spoon the whipped cream over the cake, allowing it to seep into the holes.
• Refrigerate for at least 2 hours before serving.
