Prep: Preheat oven to 350˚F. Grease a 9x13 non-stick baking pan or a Glass pyrex dish.** In a large bowl, whisk together the dry ingredients: 2 cups flour, 1 1/2 cups sugar, 1 tsp baking soda, 2 tsp baking powder, 2 tsp cinnamon.

In a second medium bowl, whisk together wet ingredients: 3 large eggs, 1 cup oil and 1 can pumpkin, until well combined.

Add wet ingredients to dry ingredients and whisk until smooth. Transfer to prepared baking dish and bake at 350˚F for 35-40 min (my oven took 35 min), or until a toothpick poked in the center comes out clean. Let cake cool completely in pan then spread the top with frosting (see below) and decorate with whole or chopped pecans. I sprinkled pecans over individual slices since my son doesn't eat them.

Combine all of your frosting ingredients in the bowl of a stand mixer and using the whisk attachment, beat on medium speed until combined, then beat on high speed 2-3 min or until fluffy, scraping down the bowl as needed.
