Preheat oven to 350 degrees F and grease a sheet cake pan well.
In a large bowl or mixer, mix all ingredients together well and pour the batter into the greased sheet cake pan.
Bake for approximately 20 minutes or until edges start pulling away from the pan. (IF the center is still a bit wet, bake for another 2-4 minutes or so.)
Allow cake to cool before frosting.
For the Frosting:
Cream all ingredients together.
Spread frosting on cake once cake is baked and cooled.
Notes
*To make this cake dairy free, simply substitute dairy-free cream cheese and vegan butter in the frosting. To keep the cake dairy free for our family, we used Trader Joe's Vegan Cream Cheese (any vegan cream cheese will do) and Earth Balance Vegan Buttery Sticks.
