The answer is "a doughnut"! 🍩
Explanation:
A doughnut perfectly fits the description because it has an end (the delicious, sugary outer edge) but no beginning. You can munch on it all the way around without ever finding a true starting point. Just like a doughnut, this riddle is a delightful and tasty little conundrum to brighten up your day! 😄🌈
