November's Cake Slice Baker's recipe was for Sweet Potato Cake with Orange Cream Filling and Chocolate Cream Frosting. We had the option of substituting something for the sweet potato, but I was curious to try the sweet potato. I've had sweet potato pie, and thought it was really good, so I was excited to try this cake. The potato puree was gorgeous- bright orange and velvety smooth, I knew the cake would be moist. We're not fans of orange flavored desserts, so I substituted almond extract and sprinkled in toffee bits. This girl couldn't wait to get a taste.I thought reserving 1 cup of frosting for the filling wasn't enough. As you can see, it was spread a little thin in places (the cakes were also not level so it was thick in some other places!). I would recommend 1 1/2 cups for the filling; there was too much for the outside. I also cut down on the amount of cream cheese and butter used in the recipe, which was still wonderful. How can you not love anything with cream cheese frosting?!!
This was a delicious, moist cake. It got rave reviews from our dinner guests, as well as my co-workers who got the leftovers! Below is my version, or check out the blog roll for the original!
Sweet Potato Cake
adapted from Sky High: Irresistible Triple-Layer Cakes by Alisa Huntsman
2 medium or 1 large sweet potato (12 ounces)
3 cups of cake flour (I substituted 2 1/4 cups all-purpose flour + 6T corn starch)
3 teaspoons of baking powder
1 and 1/2 teaspoons of ground cinnamon
1/2 teaspoon of ground nutmeg
1/4 teaspoon of cloves
5 eggs, separated
2 and 1/4 cups of sugar
1 stick butter, at room temperature
1 and 1/2 teaspoons of vanilla
1 and 1/4 cups of milk
1 cup toffee bits
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 almond cream filling smoothing it to the edge of the border. Sprinkle with toffee bits. 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.
