Preheat oven to 350ºF. In a large bowl, mix cake mix, pudding mix, egg whites, milk, sour cream, oil, vanilla, almond extract, and salt for 2 minutes. Divide and color with green and purple food coloring. Bake in prepared pans for 28-30 minutes. Cool and cut into cubes.

Whip heavy cream in a chilled bowl until stiff peaks form. In another bowl, beat cream cheese and powdered sugar until smooth. Fold whipped cream into the mixture and transfer to a piping bag.

Layer green cake cubes in jars, add 16 chopped Oreos, then pipe half of the cheesecake filling. Repeat with purple cake, then 16 more Oreos.

Pipe remaining cheesecake filling and top with an Oreo and sprinkles.

Refrigerate assembled trifles for at least 1 hour before serving.
