Baked Lemon Poppy Seed Donuts

"These lemon poppy seed donuts are oven-baked (instead of fried) and also happen to be vegan! Apple cider vinegar and baking soda serve as an egg substitute for these perfectly moist and fluffy cake donuts. All you'll need is a six-cavity donut pan! For a pop of (all-natural) color, homemade blueberry juice makes the most gorgeous lemon blueberry glaze to decorate them with. Donuts can be made a day in advance, but it's recommended to serve them immediately once glazed."
