Step 4

Pour batter into a 9x13" baking pan that has been sprayed with non-stick cooking spray.

Remove from oven and allow to cool completely on a wire cooling rack.

Step 7

Cream together cream cheese and butter until light and fluffy. Add in vanilla and mix until combined.

Step 8

Step 10

Spread frosting over bars. Slice and serve.
