I actually used cream soda in this recipe. It gives it a rich vanilla flavor. My only issue is the funnel cake is very soft and does not have a crunchy texture. I used an old plastic ketsup bottle so the batter streams were very thin. My oil was fresh and very hot. I drained it well on a bakery rack over paper towel. The flavor was grest, just a bit of a texture issue.
The taste of the finished cake was surprisingly good, I was looking for a funnel cake recipe with no milk and this is one of the only ones. I cut the recipe in half, used pepsi and skipped out on the topping and just used powdered sugar. I don't know if it was the recipes fault or my boyfriends, either from over mixing or not pouring properly but some parts ended up thick, "doughy" and gross, but the parts that stayed thin, resembled what funnel cake should and cooked through were excellent so I'm assuming its not the recipes fault. I will make again myself eventually, so if the problem was just user error ill update :)
