Preheat oven: Preheat oven to 350°F. Grease a 9x13 baking pan and set aside.
Mix wet ingredients: In a large mixing bowl, whisk together 1 cup vegetable oil, 4 eggs, 1 3/4 cups brown sugar, 1 can pumpkin puree, and 1 1/2 teaspoons vanilla extract. Set aside.
Mix dry ingredients: To a medium bowl add 2 cups flour, 2 teaspoons baking powder, 1 teaspoon baking soda, 1 teaspoon salt, 1 1/2 teaspoons ground cinnamon, 3/4 teaspoon ground nutmeg, 1/2 teaspoon ground cloves, and 1/2 teaspoon ground ginger. Use a whisk or fork to combine the dry ingredients.
Combine the wet and dry ingredients: Add the dry ingredients to the wet ingredients. Use a wooden spoon to stir until fully incorporated.
Pour into pan: Pour the batter evenly into the prepared baking pan. Bake for 30 minutes or until a toothpick inserted into the middle of the cake comes out clean.
Cool: Remove cake from the oven and allow to fully cool before frosting the cake.
Cream Cheese Frosting:
Beat the ingredients: In a small bowl, beat together the cream cheese and butter with a hand-held mixer. Add the powdered sugar, vanilla extract, pumpkin pie spice, and cinnamon. Continue beating until smooth and fluffy.
Frost cake: Spread the frosting over the cooled cake and enjoy, or you can cover and refrigerate your cake prior to serving. We prefer to refrigerate for an hour prior to serving, allowing the frosting to set.
