Robbie serves these delicious cookies at the Fourth of July get-together before the book opens and then Phil brings in another batch. This recipe was adapted with permission from the author's Hoosier sister, Barbara Bergendorf, who sells her popular snickerdoodle cookies in the greater Lafayette area. (Please contact Maddie via her website if you want to find out where to purchase these treats.)
Line two baking sheets with parchment paper.
Cream butter and sugars. Add eggs and vanilla. Mix well.
Mix soda and salt into the flour, then add the flour mixture at a low speed until blended.
Chill dough for thirty to sixty minutes.
Preheat oven to 350 degrees (F).
Form spoonfuls of dough into one-inch-diameter balls and roll in cinnamon and sugar mix.
Flatten with a fork and add blue and red sprinkles.
Bake at 350 degrees (F) about 10 minutes or until just barely tan.
