Deep-Fried Oreos are a popular fair and carnival treat made by coating Oreo cookies in a sweet batter and frying them until golden brown. The result is a warm, crispy exterior that contrasts with the soft, creamy filling of the cookie inside. Typically served hot, these indulgent snacks are often dusted with powdered sugar for added sweetness. They have gained popularity in various food festivals and events, appealing to those looking for a unique twist on a classic cookie.
