1In a small bowl, combine the first 5 ingredients. Spread evenly into a pan coated with cooking spray (I use a large cast iron skillet also sprayed) you can use a 9x13 inch baking pan. Set pan aside.
In a large bowl, combine the remaining ingredients; beat with a mixer on low speed for 30 seconds. Beat on medium for 2 minutes. Pour into prepared pan.
Bake at 350^ for 30-35 minutes or until a toothpick inserted near the center comes out clean. Cool for 5 minutes before inverting onto a serving platter. Serve warm or at room temperature . Great with ice cream of whipped cream.
