Instructions
For Cake:
Preheat the oven to 350 degrees F. Butter and flour a rectangular 9 x 13-inch pan.
In a large bowl, whisk together the flour, baking powder, baking soda, salt, cinnamon, ginger, nutmeg, and cloves.
In the bowl of your Stand Mixer, beat the brown sugar and eggs until light and fluffy. Gradually add in vegetable oil and mix until just combined. Beat in pumpkin puree and vanilla extract. Alternate the dry ingredients and milk, in three batches, and beat until combined between each addition.
Divide batter equally into prepared pans. Bake cake 20 to 25 minutes, until a cake tester inserted into the center comes out clean. Let cake cool in pan completely before frosting.
For frosting:
In a large bowl, beat all the ingredients together on low speed until combined. Increase speed to medium and beat until fluffy.
Spread frosting over cooled cake and cut into bars.
