Alex is turning 15 and the Drummonds are celebrating with Iny's Prune Cake With Buttermilk Icing for birthday breakfast after an early morning in the saddle. Then, Ree's hosting a dinner party for Alex and her best friends with personalized New York Style Chopped Salad with an Herby Ranch Dressing, home baked Rosemary Focaccia and the cutest Flower Pot Desserts. Happy birthday, Alex!
