We to get a haircut and found this newly opened donut shop. Apple fritter, lemon fill, raspberry filled, cream cheese with chocolate frosting, , a chocolate frosted old fashion, , and she threw in some donut holes.
Absolutely delectable! My first time here and I was greeted by friendly people with absolutely OUTSTANDING recommendations! If you love croissants I definitely recommend a Cronut! If you enjoy cream cream cheese the Fresh Strawberry was amazing! I don’t have it pictured because it didn’t make it home! Thank you and I plan to be back many more times!
Welcome to my new Go-To Donut shop. It's definitely worth the drive if you are not close to O'Fallon. Very nice selection of fresh-made donuts. And not bad on the price. Only has 1 2-top table so it's definitely a to-go place. We will be back!
Wow! I have been on a donut hunt across multiple states this summer. We've had plenty of decent or good donuts. But these were exceptional! Wow. She recommended the cronut and it was very tasty. Delicious. I'm partial to a good apple fritter but so many of the ones I've tried this summer have been dry, oversized, and underwhelming. This apple fritter was mind blowing! My gosh. I haven't even tried all of the other donuts we picked yet but I'm already writing my review because it was *that good.* We detoured off the highway for K&J Donuts and it was so very worth it. I'll be thinking about that fritter for a long time. Don't wait--go try K&J because they're doing things right. I also very much appreciated the fact that they put bacon crumble on the maple donut instead of a difficult-to-bite strip of bacon on top. Details matter!
Such a cute donut shop. This was our first time stopping in. When you walk in, it smells amazing! They have so many donuts to choose from, they all looked so delish. The donuts are 10/10.. Much better than any of the bigger chain places. The prices are very reasonable too. Can’t wait to go back and try the other ones that they have.
We absolutely love this local donut spot! The donuts are always fresh and delicious. But what really sets them apart is how kind and welcoming they are, especially to our kids. Every time we visit, our little ones are over the moon to pick out their favorite ones. It’s become a sweet little tradition for our family, and we’re so grateful to have this gem in our community! 🍩
Five stars for freshness and service! We visit the eureka location. These are the best donuts I've had since leaving New York. The Bavarian cream is a standout, and the friendly staff makes our weekly Sunday visit even better.
Love love love their donuts - especially the fresh strawberry one! They are always so sweet and kind in the shop. Best donuts around and cute photo opp wall, too!
Neat donut shop that was uniquely decorated with a large assortment to offer! This shop also conveniently has a drive thru as well for those weekend mornings with the kids still wearing pjs! Donuts and Breakfast croissants were consumed rapidly! Delicious!
Phenomenal fresh doughnuts! The staff were extremely friendly and kind. the chocolate cake doughnut with chocolate icing and sprinkles, as well as the glazed raspberry-filled, were delicious. They also have a cooler stocked with many different drinks. I'll definitely be coming back!
