Ingredients:

1 3/4 cups white sugar

3/4 cup vegetable oil

3 eggs

1 teaspoon vanilla extract

2 cups cooked, mashed sweet potatoes

2 cups all-purpose flour

3 teaspoons baking powder

2 teaspoons baking soda

1/4 teaspoon salt

2 teaspoons ground cinnamon

Directions:

1. Preheat the oven to 350°F. Grease and flour a 9×13-inch baking dish.

2. Stir together the sugar and vegetable oil in a large bowl until smooth. Beat in the eggs one at a time, then stir in the vanilla and sweet potatoes. Combine the flour, baking powder, baking soda, salt and cinnamon in a separate bowl; stir into the batter 1 cup at a time, alternating with the beer just until everything comes together.  Spread the batter evenly in the prepared pan.

3. Bake for 35 minutes in the preheated oven, or until a knife inserted into the center of the cake comes out clean. Cool completely before frosting or serving.
