Take your sweet potatoes off your dinner plate and use them for making this flavorful dessert. Sweet potatoes substitute for the butter in a rolled cake recipe, making this a healthier alternative to butter cakes. The cream cheese filling takes the place of a frosting, covering the top of the cake, and lends a rich, creamy flavor to this dessert.
Place the sweet potatoes into a large saucepan and pour in water to cover the potatoes. Bring the mixture to a boil and cook the sweet potatoes for 20 to 30 minutes or until very tender.
Drain the sweet potatoes through a colander and mash with a potato masher until smooth. Alternatively, puree the sweet potatoes by putting them into a food processor.
Line the bottom of a jelly roll pan with a sheet of parchment paper or spray with cooking spray. Heat the oven to 350 degrees Fahrenheit.
Beat over medium in the bowl of a stand mixer 1/2 cup cream cheese, the brown sugar and sweet potatoes until smooth and creamy.
Add the eggs to the mixer one at a time while the mixer runs on medium speed.
Pour 1 teaspoon of vanilla into the mixture in the bowl as the stand mixer runs on medium speed.
Decrease the speed of the mixer to low and spoon in the flour, baking powder, salt and ground cinnamon, until the ingredients combine thoroughly.
Pour the cake batter into the jelly roll pan and bake at 350 degrees Fahrenheit for 15 to 20 minutes or until the cake bounces back in the middle when pressed gently.
Let the cake cool in the pan completely before filling and rolling.
Beat in the stand mixer 1 cup cream cheese, the powdered sugar and 1 teaspoon of vanilla extract.
Turn the jelly roll pan upside down onto a work surface covered with a sheet of wax paper to remove the cake. Set aside the pan.
Spread the cream cheese filling with the spatula over the entire surface of the top of the cake, leaving a ½ inch margin on all sides of the top without filling.
Hold the wax paper under the cake and begin rolling the cake up along its length, using the wax paper to lift the cake from the work surface. Pull the wax paper away from the cake as you roll it until the entire cake has been rolled. Serve immediately.
