You'll need canned pumpkin, flour, and a few other ingredients to make this easy recipe. Let's get started!
Whisk together flour, baking powder, baking soda, salt, and pumpkin pie spice until just combined.
In a separate bowl, whisk together canned pumpkin, oil, eggs, and sugar.
Pour the wet ingredients into the bowl with the dry ingredients and stir until just combined.
Pour the batter into the baking dish and spread evenly. Bake for about 35 minutes.
Beat together butter, powdered sugar, cream cheese, and vanilla until light and fluffy.
Spoon the cream cheese frosting onto the cooled cake and spread with an offset spatula.
Slice the cake into squares and place a fondant pumpkin onto each slice if desired. Serve and enjoy!
