I love both ice cream and doughnuts, but I would prefer ice cream over doughnuts because they can go in many flavors, like my favorite cookies 'n cream, while doughnuts can usually go in toppings only, but it really depends. The only downsides to choosing ice cream are the brain freezes, if you're fast at eating ice cream that is...
By the way, bacon doughnuts because 'Murica. (okay, I'll leave)
