Confetti Cake Mix Cookie Butter Poke

This is the easiest “wow” cake you can make with a boxed mix: bake a confetti sheet cake, poke it all over, and pour a warm, silky cookie-butter sauce into the holes so every bite stays soft and flavorful. Then finish with a fluffy whipped topping and a shower of sprinkles.
