Mason Dixon Bakery & Bistro

In downtown Huntsville, on Church Street just off the courthouse square, Mason Dixon Bakery & Bistro has built its business around a promise that is unusual for a bakery: everything made in the kitchen is entirely gluten-free. The bakery operates as a dedicated gluten-free space, meaning no wheat flour crosses the threshold, a standard the shop has held to since it first opened.

The bakery’s roots trace back to Dr. Ashley Johnson, a chemist who lives with celiac disease and set out to apply her scientific training to gluten-free baking that did not taste like a compromise. That mission shaped the bakery’s approach from the start, favoring scratch-made recipes built on stone-ground whole grains rather than relying on pre-made gluten-free mixes. In 2024, longtime customer and communications professional Rachel Bryars took over as Owner and CEO, continuing the bakery’s local ownership while carrying forward its founding focus on honest, allergen-friendly food.

The bakery case covers a wide range of breads, including classic white, ancient grain, garlic and herb, maple cinnamon raisin, and cranberry walnut loaves, along with hamburger buns, dinner rolls, and baguettes. A paleo sandwich bread and a chocolate walnut banana bread round out the bread selection, and the shop also bakes buttermilk biscuits and a vegan biscuit option for anyone avoiding dairy as well as gluten. A take-and-bake case offers cinnamon rolls and pie crusts for customers who want to finish the baking at home.

Cupcakes are one of the bakery’s strong suits, with flavors like Cloud 9, Chocolate Heaven, Cookie Monster, Birthday Cake, Red Velvet, Carrot Cake, Fat Elvis, and Luscious Lavender, alongside a Death by Chocolate option and seasonal flavors that rotate through the year. Any cupcake flavor can also be ordered as a full cake, which makes the shop a common stop for birthdays and other celebrations in the gluten-free community around Huntsville. Muffins come in blueberry, banana nut, and apple carrot, and the cookie case includes chocolate chip, oatmeal creme pie, a house recipe called the MD Doozy, snickerdoodle, and a paleo chocolate chocolate chip option.

Beyond the bakery counter, Mason Dixon runs a bistro menu built around breakfast dishes, bowls, salads, sandwiches, and crostinis, all made in the same gluten-free kitchen. A salmon baguette is among the more distinctive bistro offerings, built on the bakery’s own gluten-free bread. The shop leans on naturally sweetened treats made with honey and better-for-you ingredients, avoiding artificial dyes, which fits with the bakery’s broader positioning as a healthy option rather than simply a gluten-free substitute for traditional baked goods.

Mason Dixon is open Tuesday through Saturday from 7 a.m. to 4 p.m. and closed Sunday and Monday. The bakery also handles corporate catering and custom cake orders, and it keeps a rewards program and gift cards available through its online ordering system. For visitors managing celiac disease, a gluten allergy, or simply looking for a scratch-made bakery in downtown Huntsville, Mason Dixon offers a menu broad enough to cover breakfast, lunch, and dessert without a single ingredient that would trigger a gluten reaction, a rare combination for a full-service bakery and bistro.

Orders can be placed ahead through the bakery’s online system for in-store pickup, and the shop also delivers through DoorDash for anyone who wants gluten-free bread, cupcakes, or a full bistro meal brought to their door. A rewards program tracks repeat visits, and gift cards are available for anyone who wants to introduce a friend or family member managing celiac disease or a gluten sensitivity to a bakery that treats those needs as the starting point rather than an afterthought. The leadership change from founder Dr. Ashley Johnson to current owner Rachel Bryars kept the bakery under local ownership, with Bryars stepping in as a customer who had already spent years relying on the shop before taking over its day-to-day operations.
