Donuts have been around in their current form since the mid-19th century. That means there's been a lot of time to perfect them. Throughout the world, you'll find a variety of different types of donuts, some great and some just mediocre. But, if you ask me, anything made with butter and sugar can't possibly be bad. Of course, rather than discuss bad or even mediocre donuts, we recommend focusing on one of the best bakeries to enjoy some of the best donuts in Bozeman, Montana.

Welcome to Granny's Gourmet Donuts located in Bozeman, Montana.

The small bakery sits just off Tai Lane in a rustic-looking, unassuming little building. Things here are simple and lovely, but it's often absolutely buzzing inside. That could be due to the sheer amount of sugar pulsing through everyone's veins. Or it could be that the vibe here is naturally fun.

With special daily donuts and a cast of regular donuts, Granny's is always an adventure.

While there are tons of unique flavor combinations, the glazed donut here is one of the best you'll ever taste. The simple raised donut comes with a light vanilla glaze made with just Bozeman water, cane powdered sugar, and real vanilla.

And this same base is used for a few other varieties, making it one of the most versatile.

There's a reason why so many of the to-go boxes are packed with the Glazed Raised.

Of course, you certainly can't overlook their famous "Donut of the Day." These are typically some of the most inventive combinations you've ever seen. Pictured here is the "Chocolate Raspberry Love Grenade." It's made using a soft donut with raspberry spread. The frosting on top is rich chocolate and it's finished with a fresh raspberry right on top.

We especially love the idea of this S'Mores Donut of the Day. It's made with chocolate ganache, honey graham cracker crumbs, and toasted mini marshmallows.

Whatever you choose to try, be prepared for a sweet treat that you'll be coming back for no matter where you live.
