Preheat oven to 375 degrees F. Lightly grease a 13?18'' half sheet pan with non-stick cooking spray.

Add butter and sugar to mixing bowl and mix until light and creamy. Add eggs one at a time, beating after each addition. Add vanilla and almond extract, and mix well.

In a separate bowl, combine flour, baking soda, and salt. Add dry ingredients to the batter and mix until combined.

Spread and press the mixture into the prepared pan.

Bake at 375 degrees F for 12-16 minutes or until the center is set and the edges are starting to be golden. Remove from the oven and allow to cool.

For the cream cheese frosting: In a mixing bowl, beat the butter and cream cheese together until smooth and creamy. Add vanilla extract and mix. Gradually add powdered sugar until smooth, adjusting the amount for desired frosting consistency.

Once the bars have cooled completely, frost and cut into squares.
