Mix each color batter in a separate bowl. When you make the yellow batter, mix the turmeric in the applesauce before adding whey and coconut flour.
Shape each dough into a rectangle, approximately 3"x5". (The orange dough will be twice as thick as the others.)
Layer the colors with the orange in the middle.
Slice into strips about ¼" wide.
To make the candy corn, make alternating diagonal cuts into each strip (see photo above).
Smooth the shape with your fingers (if desired).
Enjoy!
Notes
A note about substitutions: because each type of protein powder has a distinct flavor and texture, I would not try substituting different types of protein powders in this recipe. (See my Recipe Basics video for examples of what goes wrong when you use the wrong protein powder.)
