What You’ll Need for Snickerdoodle Blondies
For the blondies
- All-purpose flour – This is the base of the batter, so no substitutions here.
- Baking powder – Gives these blondies their perfect rise.
- Cream of tartar – The secret ingredient that gives snickerdoodles their signature tang. Don’t skip it!
- Salt – Balances the sweetness and enhances all the flavors.
- Unsalted butter – Softened at room temperature for that creamy, dreamy texture.
- Granulated sugar – Sweetens the batter and helps create that light, fluffy consistency.
- Light brown sugar – Adds a hint of molassesy depth to balance the sweetness.
- Eggs – Room temperature is key for even mixing.
- Vanilla extract – A must for that warm, comforting flavor.
For the cinnamon-sugar topping
- Granulated sugar – A simple coating for that classic snickerdoodle finish.
- Ground cinnamon – The star of the topping—use a good quality one for the best flavor.
Let’s Make This — Step by Step
I love how this easy blondie recipe with brown sugar comes together in one bowl—it feels like a little kitchen hug. Preheat your oven to 350°F and grab your favorite 9×13 pan. Trust me, lining it with parchment paper makes lifting out these Snickerdoodle Blondies so much easier later!
Whisk together your dry ingredients—flour, baking powder, cream of tartar, and salt—in a medium bowl. In your large mixing bowl, beat the softened butter, granulated sugar, and brown sugar until it’s light and fluffy. It should look like pale, creamy clouds. Add eggs one at a time, then vanilla, mixing just until combined.
Gradually add your dry ingredients to the wet, mixing on low until no flour streaks remain. Overmixing is the enemy of tender blondies! Spread the batter evenly into your prepared pan. Now, mix that cinnamon and sugar for the topping and sprinkle it generously over the top. It smells like Christmas morning already.
Bake for 25–30 minutes. You’ll know they’re done when the edges are golden and the center is set but still soft. A toothpick should come out with a few moist crumbs. Let them cool completely before slicing—I know it’s hard to wait, but it’s worth it for clean, chewy squares.
Snickerdoodle Blondies
Ingredients
- 2 1/3 cups all-purpose flour
- 2 tsp baking powder
- 1 tsp cream of tartar
- 1/2 tsp salt
- 1 cup unsalted butter softened at room temperature
- 1 1/2 cups granulated sugar
- 1/2 cup light brown sugar packed
- 2 large eggs at room temperature
- 2 tsp vanilla extract
- 1/4 cup granulated sugar for rolling
- 2 tsp ground cinnamon for rolling
Method
- Preheat your oven to 350 degrees Fahrenheit. Grease a 9×13-inch baking pan with butter or non-stick cooking spray and set it aside.
- In a medium bowl, whisk together the all-purpose flour, baking powder, cream of tartar, and salt until they are well combined.
- In a separate large bowl, use an electric mixer on medium speed to beat the softened butter, 1 1/2 cups granulated sugar, and packed light brown sugar together until the mixture is light, fluffy, and creamy, which should take about 2-3 minutes. Beat in the eggs one at a time, followed by the vanilla extract, until everything is fully incorporated.
- Gradually add the dry flour mixture to the wet butter and sugar mixture, mixing on low speed just until no streaks of flour remain. Be careful not to overmix the batter.
- In a small, shallow dish, stir together the remaining 1/4 cup of granulated sugar and the 2 teaspoons of cinnamon to create the cinnamon-sugar topping.
- Transfer the blondie batter to the prepared baking pan, using a spatula to spread it into an even layer. Sprinkle the cinnamon-sugar mixture evenly over the entire surface of the batter.
- Bake for 25-30 minutes, or until the edges are lightly golden brown and a toothpick inserted into the center comes out with a few moist crumbs attached. The center should be set but not jiggly.
- Allow the blondies to cool completely in the pan placed on a wire rack before slicing into squares for serving.

Thoughtful Tips for Special Diets
I know many of you are sugar-conscious or looking for diabetic-friendly options, so here’s how I adapt these blondies sometimes. For a lower glycemic version, I replace the granulated sugar with a natural sweetener like stevia or xylitol—just be sure to use a blend made for baking. You can also reduce the brown sugar by half for a less sweet, but still cozy, treat.
For gluten-free friends, a 1:1 gluten-free flour blend works beautifully here. And if you’re avoiding dairy, plant-based butter does the trick! Remember, baking is about joy, not perfection—make it work for you and your family.
My Favorite Pro Tips for Perfect Blondies
Over the years, I’ve picked up a few tricks to make these chewy blondies with cream of tartar even better. Here’s what I’ve learned:
- Room temperature matters – Take the time to let your butter and eggs come to room temp. It makes the batter smoother and helps the blondies bake evenly.
- Don’t overmix – Once you add the flour, mix just until combined. Overmixing leads to tough blondies—we want tender and chewy!
- Swap in whole wheat – For a nuttier flavor, replace half the all-purpose flour with whole wheat pastry flour. It adds a lovely depth.
- Storage tip – Keep these blondies in an airtight container at room temperature. If they last more than two days (they rarely do!), they freeze beautifully. For more freezer-friendly treats, see my snickerdoodle banana bread.
A Little Note on Nourishment
While these oven-baked cinnamon dessert squares are definitely a treat, I believe all food fits in a balanced life. The eggs provide protein, and using real butter instead of margarine means you’re enjoying natural fats. For more on balancing indulgences, the history of blondies and snickerdoodles shows how traditional baking can be part of joyful eating.
If you’re looking for healthier options, try my snickerdoodle protein shake for a protein-packed snack. Remember, it’s all about variety and enjoyment!
Lighter Versions and Allergy Tweaks
If you want to lighten up these buttery vanilla blondies with cinnamon swirl, here are my favorite tweaks. Replace half the butter with unsweetened applesauce for a softer, cake-like texture. You can also use a sugar alternative like monk fruit sweetener—just adjust based on package directions.
For nut allergies, these are naturally nut-free! If you need egg-free, a flax egg works well here. And if you’re out of cream of tartar, try my snickerdoodle recipe no cream of tartar version for a similar tangy flavor. For more bar cookie ideas, these cherry lemon bars are a lovely citrus option.
How to Serve These Cozy Blondies
I love serving these warm with a cold glass of milk—it takes me right back to after-school snacks at my grandma’s house. For a special treat, top them with a scoop of snickerdoodle ice cream or a dollop of whipped cream.
These make wonderful holiday dessert bars for cookie trays or gift boxes. Pair them with butterscotch pecan cookies for a variety of flavors and textures. They’re also perfect with coffee for a morning treat—I won’t tell!
Common Mistakes (And How to Avoid Them)
I’ve made my share of baking mistakes over the years, so let me help you avoid them. First, don’t use melted butter—creaming softened butter with sugar is what gives these blondies their light texture. If your butter is too soft, the blondies can become greasy.
Second, resist the urge to overbake! These chewy Snickerdoodle Blondies should be taken out when the center is just set. They continue cooking as they cool. For more on achieving that perfect soft texture, the secrets to achieving soft texture from experienced bakers can help.
Finally, make sure your baking powder is fresh. Old leavening agents can lead to flat blondies. If you love bar cookies, check out my candy bar blondies for another delicious variation.
Storing and Keeping Them Fresh
I remember baking these for my daughter’s bake sale—we made them the night before, and they were still perfectly soft the next day. Store your cooled blondies in an airtight container at room temperature for up to 4 days. They also freeze beautifully for up to 3 months—just wrap individual squares in plastic wrap and place in a freezer bag.
To refresh day-old blondies, pop them in the microwave for 10 seconds or warm them in a 300°F oven for 5 minutes. For more storage tips and other cookie recipes, visit my cookies section and cookie recipes for endless inspiration.

Frequently Asked Questions
What are Snickerdoodle blondies?
Snickerdoodle blondies are soft, chewy bar cookies that combine the flavors of classic snickerdoodle cookies—cinnamon, sugar, and that signature tang from cream of tartar—with the dense, rich texture of blondies. They’re easier than cookies because you bake them in one pan and slice them into squares!
What is a dirty blondie?
A “dirty blondie” typically refers to a blondie that includes mix-ins like chocolate chips, nuts, or caramel—adding extra flavors and textures to the classic vanilla blondie base. Our snickerdoodle version keeps it simple with just cinnamon sugar, but feel free to add chocolate chips if you’re feeling adventurous!
Is it better to underbake or overbake blondies?
It’s definitely better to slightly underbake blondies than overbake them! Blondies continue to cook as they cool in the pan, so taking them out when the edges are set but the center is still slightly soft ensures they stay chewy and moist. Overbaked blondies become dry and cake-like.
What is the secret to soft snickerdoodles?
The secret to soft snickerdoodles—and these blondies—is not overbaking and using cream of tartar, which gives that characteristic tang and helps create a soft texture. Also, creaming the butter and sugar properly incorporates air, making them lighter. For more tips, check my snickerdoodle recipe without cream of tartar if you need alternatives.
