Sprinkles Cupcakes is one of the best cupcake stores in Arizona! I've tried nearly every flavor and they are all delicious. My favorite is the chocolate marshmallow. Below is my ratings of the ones I've tried recently.
Chocolate marshmallow: 8/10 (very good balance of flavors and textures)
Cookie cupcake: 7/10 (not what I was expecting but very unique and flavorful)
Red velvet: 6/10 (cake is a little too dry and not as flavorful as others I've tried)
Black and white: 6 or 7/10 (frosting is what makes this cupcake good, cake average)
Staff were very friendly and I like how they have a vending machine option for after hours or early morning-great if you want to buy someone a gift and everywhere else is closed.
