Egg Puffs

I told Finlay to look through a cookbook and choose something for dinner. This is what he wanted and the boys loved it.

cooking spray
2 large eggs
4 large egg whites
1/2 cup butternut squash puree
2 tablespoons shredded cheese
2 tablespoons flour
1/2 teaspoon baking powder
1/4 teaspoon salt

Preheat oven to 400. Spray four custard cups with cooking spray and set on baking sheet. In a large bowl, whisk the eggs, egg whites, butternut squash, cheese, flour, baking powder, and salt until combined. Pour the mixture into the custard cups. Bake until the tops are puffed up and the eggs are not longer runny in the center when pierced with the tip of a knife (13-15 minutes).
