The Cake Slice- Sweet Potato Cake

This month's Cake Slice cake was Sweet Potato Cake with Chocolate Cream Frosting and Orange Cream Filling. It is the second cake that we have baked from Sky High . My baby is turning 2 on Thanksgiving, but I wanted to have a small party that wasn't on that day, so I am a couple days late posting this cake. I thought since I needed to make a cake anyway, I would just wait until her party to make this beautiful cake.
This cake is delish! I made it in jelly roll pans and then made a 5x5-inch square cake for the birthday girl, but made it 4 layers. The rest I cut into butterfly and flower shapes with cookie cutters. I left the sides unfrosted on the little cut-outs and they were pretty cute. The orange filling was a little bit runny and that is why the recipe said to pipe an outline of the chocolate frosting on the layers.
Overall, I was really pleased with this cake-we have only eaten the scraps (the party is later today), but my little girl had a few bites at breakfast and she was pretty happy. I am thinking this will taste really good with some pumpkin spice ice cream! Go see all the other beautiful cakes by checking out the Cake Slice Bakers!

Sweet Potato Cake:

2 medium or 1 large sweet potato (12 ounces)

3 cups of cake flour**

3 teaspoons of baking powder

1 and 1/2 teaspoons of ground cinnamon

3/4 teaspoon of ground nutmeg

1/4 teaspoon of cloves (I used allspice)

5 eggs, separated

2 and 1/4 cups of sugar

1 stick plus 2 tablespoons of butter, at room temperature

1 and 1/2 teaspoons of vanilla

1 and 1/4 cups of milk

(**The recipe calls for cake flour and if you only have all-purpose flour on hand, you can substitute 3/4 cup (105 grams) all purpose flour plus 2 tablespoons (30 grams) cornstarch.)

(*If fresh sweet potato is not available where you live you may use canned sweet potato, yams, and pumpkin puree)

Makes a 9-inch triple layer cake, serves 16-20 people

1. Preheat the oven to 400F degrees. Prick the sweet potatoes in 2-3 places, place on a small baking dish and bake for 1 hour or until the potatoes are very soft. Remove from the oven and cool slightly.

2. Reduce the oven temperature to 350F degrees. Butter the bottoms and the sides of the pans and line with parchment paper. Butter the parchment paper also.

3. When the sweet potatoes are cool peel off the skin and remove any dark spots. Cut the potatoes into chunks and puree in a food processors. Puree until smooth. Measure out one cup of potato puree and set aside.

4. Sift the flour, baking powder, cinnamon, nutmeg, and ground cloves. Set aside.

5. In the bowl of electric mixer add the egg whites and attach whip attachment. Beat on medium speed until egg whites are frothy. raise the speed to high and gradually beat in 1/4 cup of sugar. Continue to beat until the egg whites are moderately stiff.

6. In another large bowl with the paddle attachment, combine the sweet potato, butter, vanilla, and remaining sugar. Beat until light and fluffy. Add the egg yolks one at a time. Make sure to scrape the sides of the bowl after each egg yolk is added. With the mixer on low speed, add the dry ingredients and milk in alternately in 2-3 additions. making sure to begin and end with the dry ingredients.

7. With a large spatula, fold in one fourth of the egg whites into the batter to lighten. Then fold in the remaining egg whites until no streaks remain. Making sure to not over mix or this will deflate the batter. Divide the batter among of the three pans.

8. Bake for 25-30 minutes or until a cake tester comes out clean. Let the cake layers cool in the pan for 10 minutes. Then turn out the cake layers onto a wire rack and cool completely at least 1 hour.

9. To assemble the cake, place one layer flat side up on to a cake stand. With a pastry bag fitted with a 1/2 inch round tip and filled with chocolate cream cheese icing, pipe border around the edge of the cake. Fill the center with the orange cream filling smoothing it to the edge of the border. Place the second layer on top and repeat the process. Place the third layer on top and use all the chocolate cream cheese frosting to cover the top and sides of the cake.
