Preheat oven to 350˚F. Grease a 9x13 pan. In a large bowl, whisk together the dry ingredients: 2 cups flour,, 1 tsp baking soda, 2 tsp baking powder, 2 tsp cinnamon.
In a second medium bowl, whisk together wet ingredients: 3 large eggs, both sugars, 1 cup oil and 1 can pumpkin, until well combined.
Add wet ingredients to dry ingredients and whisk until smooth. Put in greased pan, bake at 350˚F for 32-38 min or until a toothpick comes out clean. Let cake cool.
Mix all the frosting ingredients together until well combined and put on cooled cake. If the frosting is too thick add a tablespoon of milk, if it's too thin, add a little more powdered sugar to get the consistency you are looking for.
