Preheat oven to 325 degrees. Mix together cake mix, jello, oil, 1/2 cup water and egg whites with hand mixer on medium speed for about 3 minutes. Scrap the sides of the bowl, add in the strawberry puree and food coloring. Mix until combined.

Spoon small amount of batter into mini doughnut tin about 2/3 of the way up. Wipe off excess on sides of mold. Bake for 7-8 minutes until toothpick inserted comes out clean.

Let cool in tin on wired rack for 5 minutes, take out doughnuts and place on wires rack to cool completely. Store in air tight container until ready to serve, before serving sprinkle with powdered sugar.

Cream together the butter and powdered sugar in a large bowl with hand mixer. Add in the vanilla and milk, whip until light and fluffy about 3 minutes. Add in the sprinkles and mix again just until combined.

Serve with mini baked doughnuts or dippers of your choice (pretzels, apple slices, graham crackers, etc.) Sprinkle on additional sprinkles for garnish if desired.

Enjoy!
