Maxie B's is Awfully Sweet to Come Back for More. Maxie B's Bakery & Dessert Café will be joining the Kirkwood 5K again in 20163 as a sponsor. As in the past, Maxie B's will generously donate 10% of their race day sales to BackPack Beginnings! Run the race, then head over to Maxie B's to replenish those lost calories with cakes & cupcakes. Treat yourself and a friend!
