Enjoy a taste of the county fair any time of year by making deep-fried Oreos in your own kitchen. Batter dip the classic chocolate sandwich cookies to make a golden-brown casing that keeps the gooey cream contained in the center. While fair and street vendors use large deep fryers to make deep-fried Oreos, a deep, thick-bottomed skillet also works. Make them in small batches to prevent the Oreos from sticking together while frying.
Place the Oreo cookies in the freezer for at least 30 minutes before dipping and frying. This freezes and firms the cream center so it retains some texture instead of immediately liquefying in the hot oil.
Prepare a thick pancake batter according to your favorite recipe; you can make the mix from scratch or use a box mix. Omit some liquid from the pancake batter recipe so the batter is a bit on the thick side, making it better able to coat the Oreo cookies. The batter should run off a spoon in long, thick strands instead of in a thin, steady stream.
Preheat cooking oil such as peanut oil or vegetable oil in a skillet or deep fryer over medium-high heat or about 375 degrees Fahrenheit. Use about 1 1/2 to 2 inches of oil when you're making fried Oreos in a skillet. The oil is properly heated when a drop of water in the oil immediately sizzles.
Dip the frozen Oreos in the pancake batter and roll them until they're well coated. Lift them from the batter and hold the cookies over the bowl for a few seconds so excess batter drips back into the bowl. You might be able to dip several Oreos at once, depending on the size of the bowl and depth of batter.
Place the Oreos carefully in the hot oil, leaving about 2 inches between each Oreo in the pan or deep fryer.
Flip the Oreos after 1 to 2 minutes or when the edges begin to turn golden brown. Fry for another 1 to 2 minutes or until evenly golden brown on all sides. If you use a deep fryer with a basket, shake the basket frequently to prevent the Oreos from sticking to the basket.
Remove the fried Oreos from the oil and transfer them to a plate lined with paper towels to absorb the excess grease. A kitchen spider tool works well for removing the Oreos.
Dust the hot, fried Oreos with powdered sugar and serve immediately. The powdered sugar coating is optional, but it adds some sweetness to the breading to make it reminiscent of funnel cakes.
