Oversized Cookies & Cinnamon Rolls at Potomac Cookie

If you’re looking to satisfy your sweet tooth, head to Potomac Cookie for oversized cookies and cinnamon rolls. Located in Gaithersburg’s Kentlands, they bake everything from scratch, in-house, daily, and yes, you can taste the difference.

Their cookies run $6.25–$7.25 depending on flavor, made with premium ingredients and no artificial additives. Flavors rotate often, so there’s always something new to try! On my latest visit, my fave was the Dubai Chocolate Chip (SO good – stuffed with pistachio & knafeh) with Ferrero Rocher as a very close second.


What to Order

  • Dubai Chocolate Chip – chocolate chip base, pistachio & knafeh filling. So freaking good.
  • Ferrero Rocher – chocolate-hazelnut dream for Nutella lovers.
  • Cinnamon Rolls – they offer two decadent styles in addition to the cookie lineup.
  • Drinks – grab a matcha or coffee to wash things down.

Potomac Cookie checks all the boxes: oversized, from-scratch treats baked in-house daily, premium ingredients with no artificial additives, and a rotating menu that keeps things exciting with new flavors. It’s also a black and woman-owned small biz, AND it’s in Kentlands, where you’re surrounded by tons of restaurants, bakeries, and shops – perfect for a little dessert-and-stroll situation.

If you’re making a full Gaithersburg food day of it, add Pâte à Cake for Japanese cheesecake and soymilk custard cake, then wrap the night up with dinner at Koi Sushi at Rio Lakefront.
