For some real state-fair style concoctions, go the candy bar route.
Grab some of your favourite chocolate bars (SNICKERS!!!!, Milky Way, Kit Kat...)
use a simple recipe for funnel cake batter, such as this:
1 1/3 cups flour
1/4 teaspoon salt
1/2 teaspoon baking soda
2 1/2 tablespoons sugar
3/4 teaspoon baking powder
1 egg, beaten
3/4 cup milk
1 teaspoon vanilla
In a large bowl, mix all dry ingredients. Beat egg, milk, and vanilla together in a separate bowl. Add milk mixture to dry ingredients beating until smooth.
Batter the candy bar and drop in the deep fryer for a few minutes until golden brown. For an added touch, top with some powdered sugar or cocoa.
For an extra touch, try sticking popsicle sticks into the candy bars first, this allows for easier consumption.
Hope the first heart attack is a good one!
