Mashed potatoes go perfectly with lots of things. Steak. Pot roast. And apparently donuts. Mashed potatoes are the secret to this Uptown spot's recipe. This means the donuts at Downstate have a unique texture that's soft and creamy, but just a little bit cakey. So if you can never decide between cake or yeast, this is the Goldilocks donut you've been looking for. They have flavors like sweet potato maple, Vietnamese coffee, and Japanese pancake with hints of butterscotch and a berry jam drizzle.
