These gluten-free snickerdoodle bars have all the flavor of a classic snickerdoodle cookie but in an easy, sliceable bar format. The dough comes together in one bowl with no mixer and no chilling required, which makes them one of the faster bar recipes on the site. Melted butter instead of softened butter is what keeps them thick and chewy all the way through.
The cinnamon sugar topping goes on right before baking and gives you that classic snickerdoodle coating without having to roll individual dough balls. One 9×13 pan makes 18 bars, which is enough to bring somewhere or stock the freezer for later.
Why You’ll Love This Recipe

Ingredient Notes
- Gluten-Free Flour Blend – Tested with Bob’s Red Mill 1-to-1 and King Arthur Measure for Measure. Both already contain xanthan gum. I can’t guarantee results with other blends.
- Cream of Tartar – What gives these bars their snickerdoodle flavor. Without it you’d just have a cinnamon sugar bar. Don’t skip it.
- Melted Butter – Using melted rather than softened butter is what makes these bars thick and chewy. Let it cool slightly before mixing in so it doesn’t scramble the eggs.
- Brown Sugar – The combination of brown and granulated sugar gives these bars chew and flavor. Don’t swap it out for all white sugar.
- Cinnamon Sugar Topping – Go heavy with it. A generous coating on top is what gives you that classic snickerdoodle finish.
Why I Include Metric Measurements
Measuring ingredients by weight gives you consistent results every single time. Gluten-free flour is especially sensitive to how it’s scooped, so even a small variation can affect how these bars turn out. I’ve included grams for every ingredient in the recipe card so you can just weigh as you go. Once you start baking by weight, you’ll never go back to cups.

Recipe FAQs
Traditional snickerdoodles are not gluten-free because they’re made with all-purpose flour. This recipe uses a gluten-free flour blend to make them gluten-free.
The most common reason is overbaking. Pull them when the edges are set and the center no longer looks shiny. They’ll firm up as they cool and will be dry if you leave them in too long.
Expert Tips
Storage Instructions
- Room Temperature: Store in an airtight container for up to 2-3 days.
- Freezer: Freeze in a single layer on a sheet pan until solid, then transfer to a freezer-safe bag or container for up to 3 months. Thaw at room temperature for about 30 minutes before eating.
- Make Ahead: These bars are great for making ahead. Bake a day in advance and store at room temperature overnight. The texture is just as good the next day.

Serving Suggestions
These bars are easy to slice and stack, which makes them good for bringing somewhere or packing into a treat box. They go well alongside my gluten-free snickerdoodles if you want the cookie and bar version of the same flavor on one platter. For a full bar spread, my gluten-free chocolate chip cookie bars and gluten-free blondies are made in the same 9×13 pan and slice up the same way, so you can make all three and cut them into similar sized pieces for a crowd.
