Cake:
1 1/2 cups unbleached all purpose flour
3/4 tsp baking powder
3/4 tsp baking soda
1/2 tsp salt
1 1/2 tsp cinnamon
3/4 tsp ground ginger
1 cup canned pumpkin (not pumpkin pie filling)
1 cup sugar
1/2 cup canola or corn oil
2 lrg eggs
1 12oz bag semisweet choc chips
Frosting:
1 stick unsalted butter
room temperature
4 oz cream cheese, room temp
1 tsp vanilla
1 3/4 cup powdered sugar
Position rack in cener of oven. Butter a 9" square baking pan. Line the bottom of the pan with parchment paper and butter the paper. (I used an 8"pan and it was ok)
Sift the flour, baking powder, baking soda, salt, cinnamon, and ginger into medium bowl and set aside.
In a lrg bowl, using and electric mixer on med speed, beat the pumpkin, sugar, and oil until smooth, about a minute. Scrape side of bowl as necessary. Mix in the eggs one at a time until blended. On low speed, add the flour mix, mixing just until incoorporated. Mix in chocolate chips until evenly distributed.
Scrape the batter into the pan. Bake just until the top feels firm and toothpick inserted comes out clean, approx 40 min. (Mine took 36) Transfer cake to wire rack to cool for at least 20 min.
Run a knife around the edge of the pan and invert the cake onto the wire rack. Remove the paper liner and let cake cool completely.
Make frosting:
Using an electric mixer on low speed, beat the butter, cream cheese and vanilla until thoroughly blended and smooth, about 1 minute. Scrape down sides of bowl. Add the powdered sugar, mixing until smooth, about 1 min, then beat on medium speed for about a minute to lighten it up.
Frost the top of the cake. I garnished the top with shaved chocolate.
The cake can be refrigerated up to 3 days, just let stand at room temp an hour before serving.
