I wouldn't even call it a recipe because they are so easy to make! I must give credit to my friend, Chapell, for showing me how to make them many years ago.
Vegetable oil (or any other cooking oil that you prefer)
Canned biscuit dough
Granulated sugar and/or powdered sugar
1. Pour a significant amount of cooking oil into a small pot. You can also use a fryer if you have one. Heat vegetable oil at medium-high heat.
2. Flatten each biscuit and cut out a hole in the center with a knife. (For the doughnuts above, I used a cookie cutter for the star and heart shapes. I took the dough around the edges and rolled it into balls for doughnut holes.)
3. Drop a doughnut hole into the oil to determine if it's hot enough. It will float to the top if the oil is ready or sink to the bottom if it isn't.
4. When the oil is hot enough, drop each biscuit into the cooking oil. I usually cook one doughnut and two holes at a time. Depending on the size of the pot you're using, you can obviously cook more than that. Just make sure the doughnuts aren't too close to each other because they will stick together.
There's no hard and fast rule for timing when to flip the doughnut over. I eyeball it, and flip it with a fork when it begins to turn a light golden brown. This happens quickly! You also want to be sure the doughnuts aren't too thick and that you flatten them really well because they can turn out gooey inside.
5. When the doughnuts turn golden brown, remove them from the pot with a slotted spoon or spatula. Place the doughnuts on a paper towel covered plate to soak up the oil. Allow them to cool for approximately 3-4 minutes.
6. Drop each doughnut into a Ziploc bag with granulated sugar and/or powdered sugar, and shake bag to coat doughnuts. You don't need a whole lot. You only need enough to coat them and I usually throw several in at a time.
That's all it takes to make yummy doughnuts that taste like funnel cakes and in only a matter of minutes!
