Graduation Season is Wrapping Up 🎓

Caps have flown, tassels have turned, and graduation season is wrapping up in the sweetest way. We’ve loved being part of your celebrations this year - from preschool graduations to college send-offs and every proud family moment in between.

We’re still taking graduation cookie orders, but this Friday (5/29/26) is nearing capacity. If you need cookies for that day, please order ASAP.

Regardless, we will keep our front cases fully stocked with grab-and-go treats for last-minute needs, gifts, and celebrations. Whether you need a thoughtful dessert for a grad party or just want to surprise your favorite graduate with something sweet, we’ve got you covered.

Thank you for letting us help celebrate such meaningful milestones with you all. Here’s to new adventures, big dreams, and plenty of cookies along the way!

Summer Celebration Cookies

The grills are firing up, the school countdown is officially on, and summer is just around the corner. Memorial Day weekend always feels like the start of something special - slower evenings, backyard gatherings, pool days, and making memories with the people we love most.

Whether you’re hosting family, heading to a neighborhood cookout, or simply celebrating the start of summer break, we’ve got cookies ready to make the weekend a little sweeter. Stop by for festive treats that are perfect for sharing after the parade, packing for a picnic, or surprising the kids as they kick off summer vacation.
