Step 1: Preheat and Prepare: Preheat oven to 350F (175C). Grease and flour a 9x13 inch baking pan. Ensure even baking and easy cake removal.
Step 2: Combine Cake Ingredients: In a large mixing bowl, combine spice cake mix, pumpkin puree, vegetable oil, eggs, and pumpkin pie spice (if using). Blend until just combined, ensuring no large lumps remain. Overmixing can result in a tough cake.
Step 3: Bake the Cake: Pour batter into prepared pan and spread evenly. Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean or with a few moist crumbs. Avoid opening the oven frequently during baking to maintain consistent temperature.
Step 4: Cool the Cake: Allow the cake to cool in the pan for 10 minutes before inverting it onto a wire rack to cool completely. Ensure the cake is thoroughly cooled before frosting to prevent melting.
Step 5: Prepare the Frosting: In a large mixing bowl, beat softened cream cheese and butter until smooth and creamy. Add powdered sugar gradually, beating until well combined. Stir in vanilla extract and salt. Adjust powdered sugar for desired consistency.
Step 6: Frost the Cake: Once the cake is completely cooled, spread the cream cheese frosting evenly over the top. The frosting should be thick enough to hold its shape but easy to spread.
Step 7: Garnish (Optional): Garnish with a sprinkle of cinnamon, chopped pecans, or a drizzle of caramel sauce for added visual appeal and flavor. These additions can enhance the overall presentation of the cake.
Step 8: Serve and Enjoy: Cut the cake into squares and serve. Store any leftover cake in an airtight container in the refrigerator to maintain its moistness and freshness.
For a richer flavor, substitute melted butter for vegetable oil. Add 1/2 cup of chopped walnuts or pecans to the cake batter for added texture. For a dairy-free option, use a dairy-free cream cheese alternative for the frosting.
