Preheat oven to 350 degrees and line cupcake pan with liners
In a large mixing bowl mix cake mix, flour, sugar and salt.
Blend in water, oil and sour cream until smooth
Add almond and vanilla extracts and blend well
In a separate bowl using a wire whisk beat 4 egg whites until firm peaks form
fold in the egg whites until mixed well
I use a wilton cupcake scoop but an ice cream scoop also work and fill the cupcake wells
Bake for 17-19 minutes.. check them when then are slightly brown and spring back they are done
Cool on a wire rack and frost when cool The always look nice if you pipe on the frosting
