I have adapted the recipe from Bon Apetit (you will notice the magazine in some of the pix), mostly because I just can't do exactly as told. Ever. My advice for those of you inspired by this Instructable is to follow the basic instructions and not to copy my actions - unless you like to take the long way.
Always make sure you have ingredients and hardware on hand BEFORE starting the project. Just this once, I was prepared and did not have to run out midway - thanks to my previous pumpkin torte success/debacle, I had already purchased heavy whipping cream.
2 9" round cake pans
big mixing bowl - or three, if you don't want to wash between steps
2 smaller bowls
A marvelous electric mixer - if not, then a sturdy spoon, lots of patience, and serious biceps.
a long serrated knife
a rubber spatula
a wide dull knife (aka frosting spatula)
The Cake Ingredients
3 cups all purpose flour
2 teaspoons baking soda
2 teaspoons baking powder
1 15 oz. can pumpkin pie filling***
1/2 cup sugar
1 1/4 cup vegetable oil
4 large eggs
The Frosting Ingredients
1 1# box powdered sugar
1/2 cup + 1Tbsp heavy whipping cream
1 tsp vanilla extract
1 8oz. package cream cheese, room temperature
1/4 cup (1/2 stick) unsalted butter, room temperature
***The original recipe called for pure pumpkin , 1 1/2 cup sugar, and a host of spices. To save time, I hacked it and used Libby's pie filling, decreasing sugar. It worked.
