Are Glazed Donuts Vegan?

As someone who is transitioning to a vegan lifestyle, I’m curious if glazed donuts are vegan-friendly. Donuts used to be one of my favorite treats, but now I want to make sure that the food I eat aligns with my values. Is the glaze on donuts made with any animal-derived ingredients? Are there any other animal products used in the dough or toppings? It’s important for me to ensure that I’m not compromising my ethics when enjoying a sweet treat.
