Preheat the oven to 350 degrees F. Oil a 9x13 glass pan with oil.
In a bowl, combine the sweet potato, eggs, oil, syrup, applesauce, and vanilla together and whisk fully.
Add the remaining ingredients and mix into the wet until fully combined, leaving no streaks of flour.
Pour the prepared dish, smooth the top, and bake for 35-40 minutes, or until a toothpick comes out clean when inserted into the center. Let cool before frosting.
