Beaver tails are essentially a stretched dough that is deep fried and covered with cinnamon sugar. You can enjoy it as is or add just about any topping that you can think of on top! The most popular one available at the Beaver Tails chain is the Killaloe Sunrise, which is cinnamon sugar and fresh lemon juice. Another favourite is the Chocolate Hazelnut, which is a Beaver Tail covered with a chocolate hazelnut spread.
