Step 1

Preheat oven to 350°F and grease a 13 x 9 inch pan.

Step 2

Combine all of the ingredients in a large bowl and beat with a hand mixer on medium-high speed until light and fluffy.

Step 3

Pour into the pan and bake for 50-60 minutes, or until lightly browned on the edges and nearly set (it will still jiggle slightly in the center).

Step 4

Cool to room temperature, then chill in the refrigerator before serving.
