Preheat oven to 350 degrees F. Line a 13x9" baking pan with foil, extending the sides of the foil over the edges of the pan. Spray the foil liberally with cooking spray; set aside.

In a large bowl, combine the confetti cake mix, egg and melted butter, stirring until a soft dough forms. Press the dough into the prepared pan in an even layer. Set aside briefly.

Wipe out the bowl and add in the cream cheese and eggs, beating well until combined. Add in the almond extract and the powdered sugar, beating well. Lastly, beat in the melted butter, then stir in the sprinkles to combine.

Pour the filling over the crust and bake for approx. 35-40 minutes or until the top is light golden brown and the center is just about set. It may still look a little jiggly, but this is okay - you do not want to over-bake them! Cool completely, then refrigerate for at least 2 hours before cutting into bars.
