Preheat the oven to 350 degrees and spray a 12 count mini donut pan with non-stick cooking spray.
Combine the cake mix, egg whites, oil and water.
Add a few drops of pink food coloring to the batter and stir to combine.
Scoop the batter into the large freezer bag.
Snip the corner of the freezer bag and fill the mini donut wells with batter.
Bake 6-8 minutes.
Remove from the oven and let cool.
Once the donuts have cooled, remove them from the donut pan and set aside.
Combine the powdered sugar and creamer.
Add 1 drop of each food coloring to the glaze.
Use a toothpick to gently swirl the colors (be careful to not completely mix the colors together).
Dip the donuts one at a time in the glaze and then add sprinkles.
After dipping 2-3 donuts in the glaze, add another drop of each food coloring and gently swirl the colors.
Repeat with all donuts.
