Heading into Cookeville today on errands I searched out the highest rated donut shops and read reviews. The owner of Big O Donuts replied as he should to an improper review and so off I went. Walking in there are cases of donuts wall to wall! Nice, good sized donuts with many choices. I picked the large apple fritter and a dozen filled and miscellaneous ones that looked great. Everything looked great! I've eaten and sampled more than half. The apple fritter, glazed old fashion, chocolate old fashion, peanut butter and jelly and the apple crumb were fantastic!! Plenty of filling and very fresh flavors and textures. I'm in the midst of a sugar coma now but the remaining 5 will be gone today some time. Looks like I've definitely found my TN donut stop!! Don't waste your time with others. If you are looking for fresh, PROPERLY MADE donuts then look no further! read more

Great donuts! Good variety, fresh! I took a selection to my doctor's office visit, I had to wait to see the doctor because all the staff stopped to get the donuts! I made a lot of new friends with my Big O Donut donation! read more

Wife stopped and got some tasty doughnuts and a couple of biscuit sandwiches.. we really enjoyed them and in all honesty we thought these were better than the "other" place. read more

Oh my! What can I say about Big O... nothing! What are you waiting on! Seriously, this place is amazing! The staff are welcoming and wonderful. The value is ridiculously reasonable. It's always clean. There is an option for everyone. Oh, and by the way, there are way more options than doughnuts! Of course, they are the main attraction, but they aren't the only menu item. Bring a friend because you won't be able to pick just one, and the size needs to be shared. read more

The pumpkin cake donut was good with it not being over whelming with pumpkin & spices. The cashier wasn't very welcoming with no smile and seemed to not wanting to be there but that's what you get since Covid . On the way back from our vacation I will be going to Ralph's Donuts ( they are closed on Sundays or I would have). read more

The absolute best small town business with the most delicious donuts anywhere hands down!!!

Passed through Cookeville and came here because Ralph's was closed but it satisfied the craving. Word of advice stick to the yeast or filled donuts they taste the freshest. The cake ones we had were subpar always lacking the level of moisture to make the donut truly shine. My favorite of the bunch was the Custard Filled wish I had gotten a Cream Filled that would've made it 5/5 review! There was something ominous about the chocolate glaze at first glance but heat it up and those doubts will melt away. Also get there earlier than noon for the best options I saw they were completely out of stock of the Apple fritters and Cinnamon rolls which only means they are most popular. read more

Love Big O donuts!!! Breakfast sandwiches or donuts, you cannot go wrong!!! They always have fun seasonal options as well!!

Imagine creme and jelly-filled donuts that are so full it squishes out with every bite. That is what you will find here. Apple fritters (in several sizes) made with real apples. Yummy, fresh donuts from traditional to creative - all consistently binge-worthy. Friendly, knowledgeable service in a clean, welcoming atmosphere. read more

Loved the vanilla cream... chocolate was good, just needed more cocoa powder to the cream and skip the chocolate topping. (It flaked off in the car). Great service! Rock on! read more

Good atmosphere and donuts, unfortunately the cashier was a bit rude and not very welcoming read more

Big O donuts are scrumptious!! (personally) I believe Big O is the best thing Cookeville's got going. Not only does Big O have the best donuts in town but breakfast sandwiches that'll knock your socks off:) And thanks to Big O I don't have to make biscuits anymore The staff are friendly. The restrooms are always clean. Lots of room to sit and enjoy what you've purchased, my favorite is a good old fashioned glaze donut and a cup of coffee. I give Big O 5stars. read more

Hands down, the best donut in Cookeville. Service is prompt and friendly. Atmosphere is that of a 50's donut shop with amazing smellz

Arrived at 7 am to get the holiday donuts that were posted on their social media. When we got there the cashier was rude and seemed annoyed when asked where the holiday donuts were. He stated they would be out in "20, 30 mins, i don't even know" with a bothered tone. We ended up getting ones that were already out since we had somewhere to be, these donuts were cold, hard and stale. I wouldn't be surprised if they were from yesterday. I gave two stars because the iced coffees were decent but did toss the donuts after one bite. read more

We were in Cookeville to tour TN Tech and of course had to try out Big O. I only got a couple of kinds, but the glazed is fantastic! It's light, fluffy, and moist. Can't wait to go back and get them again! read more

Sypped at Big O before starting our earns for the day on a Sunday morning. Ordered a breakfast sandwich and it was delicious and super fresh. Also ordered some donuts and they were amazing. I especially loved the chocolate creme donut. Will definitely being going back. read more

We're from out of town, stopped in on Easter as not many places were open. So glad we did! We were met with warm friends faces. Left with full tummies and a cool shirt. 10/10 read more

Big O is one of the few donut joints that I have found in Tennessee that offers Maple Bars! They are very prevalent ( aaaand delicious! ) in the West coast but nonexistent in the South. However, Big O is wildly inconsistent with quality and freshness. More than a few times I have come away disappointed because the donuts are stale, or even worse, burnt. read more

Omg if love donuts please please stop at this place ! Chocolate covered loaded lemon filled donut a true maple doughnut and a fabulous cinnamon filled apple fritter ...please support local businesses! read more

THE BIGGEST DONUTS!!! And oh so yummy too! I had an applied crisp donut and my friend had a coconut one. Literally some of the best donuts I've ever eaten. Can't wait to go back to this cute little shop! read more

Donuts is my favorite food group! We each had a loaded tenderloin biscuit with a bag of donuts on the side to go. They are pretty good. Maybe not the best I ever had (that goes to Shipley's in Texas) but dang good anyway! read more

I've had better donuts than the ones at Big O's, but given the limited supply in the area, they are decently good. Below is what we got: PUMPKIN: not as spiced as other pumpkin ones I've had elsewhere and the glaze overpowered the donut. I wish they had plain pumpkin with no glaze! BAVARIAN CREME: the ratio of creme to donut was less than what I was hoping. It seemed like I ate half of the donut without getting any creme. The chocolate glaze was yummy. PLAIN: this donut was very chewy, and the flavor was dull. CHOCOLATE GLAZED: soft donut and good glaze but nothing special that stood out. REGULAR GLAZED: the best one! The donut was soft and the glaze was sweet enough but not too over-powering. I wish I got a dozen of these! Overall, I recommend that Big O's have more variety of glazed and not-glazed versions of their donuts, but I highly recommend the regular ol' glazed if you stop by for something sweet. read more

Cookeville seems to really love donuts (since there's at least 4 donuts shops throughout town) and these are definitely great donuts! We stopped in a few weeks ago to try a couple of them and we weren't disappointed. The glazed blueberry and cinnamon crunch donuts were out of this world and we are definitely going to come back to try some more! read more

My family just pulled into town yesterday, moving to Cookeville. Fist things first, this morning I took my 8 year old to find the best donut shop in town. I asked the girl behind the counter "how do you make your lattes?" & she said "they do it in the back". I asked, "oh, but is it a push-button machine or do you pull your espresso shots with an espresso machine". She said "I have no idea". I asked, "can you ask someone?". She came back from the back & said "we make them with a machine". I asked, "is the owner back there, can I just ask them?" & she said "yes". She went into the back, came back & said "he said he's busy". Well, that is a loud & clear message. I'll never cross that threshold again. What a genius, running business off to corporate giants, unfortunately Ralph's (which we had been told is the best in town) was closed (Sunday) so we ended up at Dunkin Donuts. read more

Like every donut place... gotta get there pretty early for the good stuff! But if you do get the donuts are when stocked "big O" is not an understatement! Big cream filled donuts are delicious' I haven't tried their breakfast menu yet, but I'm willing to try! read more

We love Big O's!!! Great atmosphere amazing biscuit and country gravy!! The donuts are wonderful!! The service is outstanding!!!

I'm only giving this place two points because the donuts were good. The gal behind the counter was very rude and short with this. I would not come again if I were in Tennessee. read more

Huge donuts. Delicious. Great biscuits too. Large portions and cheap! We couldn't believe how much food we got for the price. Biscuits were soft and warm. Sausage and bacon both good. Again the donuts were great. Flaky and fresh. Filled and not filled we're both yummy. read more

I just want donuts. I just want a place open 24 hours and have free wifi. This place has all of that. I've been going to Big O's for two years, I feel they have the best donuts in town. Never had a problem and the staff is really nice. Just a place to hang out and eat donuts. That's all I want. Nothing fancy. Just donuts. read more

Hate that they are no long open 24/7. Change location and hours and it's just not the same.

Best donut spot I've ever been to! Excellent service, close to Tenn. Tech campus and open 24/7; my personal go to spot for road trip pit stops. The cinnamon rolls and apple fritters are as big as your face (no joke)! Great variety of donuts, breakfast foods and coffees. They even have ice cream! What I personally call "The Big O" is a donut topped with ice cream. The warm donut and cold ice cream are great complements. 5/5 will always recommend! read more

Yum best donuts open 24/7 fresh at all times just over all amazing love the raspberry jelly.

The "other more famous" place in town gets the better write ups and publicity. And they do have a great array of unusual donuts. But if you just want a great glazed, chocolate covered, or creme filled, well, we pick Big O - as someone else said the glazed are light and fluffy and the rest are just as good. read more

Whoa this place is absolutely my favorite when I'm in town!! I will only recommend The Big O Doughnut shop!

Donuts are great....but....this is the first donut shop in my whole life that I had to PAY FOR MILK to put in my coffee!!!

Great donuts for a great price. In a college town, that's all you can really ask for. Nice employee(s) every time I go. Seating is good, and the tables are well stocked. Big O's is a quality, small town donut shop if there ever was one! read more
