From Pillsbury Super Moist Cake Mix Recipes. This looks really good. It says for a fun soda fountain touch, insert half of a plastic straw into each piece of cake.

- 1 (1 lb) container vanilla frosting (Betty Crocker Rich & Creamy preferred)
- 1⁄2 cup crushed root beer flavored hard candies (about 10)
- Heat oven to 350F (325 for dark or nonstick pan).
- Spray bottom only of 13 x 9-inch baking spray with flour. (For maximum cake height, keep baking spray off the sides of the pan. The cake will climb the sides of the pan better.
