I generally just go with the standard recipe found on the side of the Bisquick box. I think it is actually pretty good. I however jazz up my waffles by using a variety of toppings. There is always the standard butter and syrup, but equally as good is vanilla yogurt with fresh fruit and granola on top. I also like fresh fruit with whipped cream on them too. You can always stir in a fruit such as strawberries or blueberries into the batter to add a little different twist to it. Oh, and vanilla yogurt with chocolate chips as a waffle topping rocks!
Enjoy your new waffle maker!
