Snickerdoodle bars with a cinnamon sugar crust capture the warmth of fall baking in the simplest way.
These chewy squares come together in one bowl, and the oven does most of the work. You get that golden crust, a soft buttery center, and the nostalgic flavor of cinnamon all in one bite.
This recipe teaches you exactly how to make a pan of thick bars that hold their shape, pack well for gatherings, and taste like a classic autumn memory. You will also learn why each ingredient matters and how small choices change the outcome. That knowledge is what makes a baker confident.
I have baked many snickerdoodle dessert recipes over the years, and this one stays close to me. It brings ease to the process without losing the heart of what a snickerdoodle should taste like. These bars belong on any list of bake sale treats, family desserts, or easy autumn recipes that never disappoint.
Why Butter and Sugar Create the Foundation
Softened unsalted butter gives these cinnamon bars their richness and structure. Creaming butter with sugar introduces air, which helps create that light texture you notice in every bite.
I prefer unsalted butter because it lets me control the salt. Salt balances sweetness in a way nothing else can. Granulated sugar, in turn, keeps the crumb soft while helping the top crust form its golden edge.
In my own tests, reducing the sugar by much more than a few tablespoons weakens that top crackle. If you love the classic crunch, trust the ratio written here.
Eggs and Vanilla Build Warmth and Stability
Eggs are more than a binder. They add body and moisture that keep the bars chewy. Each egg enriches the batter and supports the rise in the oven.
Vanilla extract lifts the cinnamon flavor rather than competing with it. Without it, the spice tastes sharper. With it, you taste balance. That is the difference between a simple cinnamon dessert and one you remember.
For another spin on spiced fall flavors, I keep Snickerdoodle Cobbler close to this recipe. Both remind me why cinnamon and vanilla feel timeless when paired together.
Flour, Cream of Tartar, and Baking Soda Make It a Snickerdoodle
This combination defines the character of these snickerdoodle bars. All-purpose flour gives the batter enough structure without heaviness.
Cream of tartar delivers that signature tang unique to snickerdoodle desserts. Leave it out, and you have cinnamon cookie bars, but not true snickerdoodles. Baking soda reacts with the cream of tartar to create lift. That lift keeps the center tender rather than dense.
Salt works in the background here. It rounds out the sweetness and keeps every bite balance.
Cinnamon Sugar Crust Brings the Magic
The topping is what sets these apart from many bar desserts. A simple blend of granulated sugar and ground cinnamon melts slightly in the oven. It bakes into a crisp crust that crackles when you cut through.
I find that evenly sprinkling the mixture across the top matters. Piling it in one place causes dark spots that taste bitter. A light, uniform layer makes every square shine.

Baking Notes That Save the Day
The oven does much of the work, but timing is key. Bake until the edges turn lightly golden and the center looks just set. Do not wait for the middle to look fully firm. That small bit of softness creates chewiness once cooled.
I sometimes underbake by one minute for that exact reason. Then I let the bars cool fully in the pan before lifting them out. The texture settles into that balance between soft and sturdy.
Brown Butter Snickerdoodle Bars show another path here. Browning butter first adds a nutty depth that changes the flavor entirely. It is worth trying once you know the classic method.
Serving Ideas Beyond the Pan
These bars cut neatly, which makes them one of my go-to bake sale treats. Stack them in parchment-lined tins, or wrap them individually for easy sharing.
I also like serving them with a drizzle of caramel sauce when I want a plated dessert. The cinnamon sugar crust holds up well under the sauce.
Another fun idea is to serve them warm with ice cream. Vanilla softens the spice, while cinnamon rolls into the cold cream beautifully.
Storing for Freshness and Flavor
An airtight container at room temperature keeps these bars soft for up to four days. They do not dry out quickly, which is another reason I return to this recipe often.
If you plan ahead, freeze the cooled bars in layers separated by parchment. They thaw in about an hour and taste as good as fresh. I sometimes tuck a few into the freezer for a last-minute treat when guests arrive.
For another freezer-friendly dessert, Snickerdoodle Blondies offer a chewy twist that keeps just as well.

Ingredients
- FOR THE DOUGH:
- 1 cup (2 sticks) unsalted butter, softened
- 1 ½ cups granulated sugar
- 2 large eggs
- 2 tsp pure vanilla extract
- 2 ¾ cups all-purpose flour
- 1 ½ tsp cream of tartar
- ½ tsp baking soda
- ¼ tsp salt
- FOR THE CINNAMON SUGAR CRUST:
- 3 tbsp granulated sugar
- 1 ½ tsp ground cinnamon
Instructions
- PREHEAT & PREPARE: Preheat the oven to 350°F (175°C). Grease a 9x13-inch baking pan and line it with parchment paper, leaving an overhang on the sides for easy removal.
- CREAM THE BUTTER AND SUGAR: In a large mixing bowl, cream the softened butter and granulated sugar together using an electric mixer on medium speed until the mixture is light and fluffy, about 3 minutes.
- ADD EGGS AND VANILLA: Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract until fully incorporated.
- MIX DRY INGREDIENTS SEPARATELY: In a separate bowl, whisk together the flour, cream of tartar, baking soda, and salt. Gradually add the dry mixture to the wet ingredients, mixing on low speed until just combined. The dough will be thick.
- PRESS THE DOUGH INTO THE PAN: Spread the dough evenly into the prepared pan using a spatula or your hands, pressing it firmly into the corners to create an even layer.
- ADD THE CINNAMON SUGAR TOPPING: In a small bowl, mix the granulated sugar and ground cinnamon. Sprinkle the mixture evenly over the top of the dough to create a uniform crust.
- BAKE: Bake for 22–25 minutes, or until the edges are lightly golden and the center is just set. Avoid overbaking to maintain a soft texture in the center.
- COOL AND SLICE: Allow the bars to cool completely in the pan. Once cooled, lift them out using the parchment overhang and cut into squares for serving.
Notes
Store in an airtight container at room temperature for up to 4 days. For a slightly chewier texture, underbake by one minute and let cool fully in the pan.
