Ingredients You’ll Need

1/2 cup (115g) unsalted butter, melted
1 cup (200g) granulated sugar
2 large eggs
1 tsp vanilla extract
1/2 tsp baking powder
1/4 tsp salt
1 cup (125g) all-purpose flour

For the Cinnamon Swirl:

2 tbsp (25g) granulated sugar
1 tbsp ground cinnamon

How to Make Soft and Chewy Snickerdoodle Blondies

Preheat & Prep: Start by preheating your oven to 350°F (175°C). Grease an 8×8-inch baking pan or line it with parchment paper for easy removal later.
Mix the Blondie Batter: In a large bowl, whisk together the melted butter and granulated sugar until smooth and glossy. Add eggs one at a time, whisking well after each addition, then stir in the vanilla extract.
Add Dry Ingredients: Mix in the baking powder and salt. Gradually fold in the flour, stirring just until combined. Be careful not to overmix—this keeps the blondies tender and soft.
Create the Cinnamon Swirl: In a small bowl, combine the sugar and cinnamon for the swirl. Spread half of the blondie batter evenly into the prepared pan. Sprinkle half of the cinnamon-sugar mixture over the batter.
Layer & Swirl: Gently spread the remaining batter over the cinnamon layer. Sprinkle the rest of the cinnamon-sugar mixture on top. Using a knife or toothpick, swirl the top layer to create a beautiful marbled effect.
Bake to Perfection: Bake for 25-30 minutes until the edges are golden and a toothpick inserted in the center comes out clean. Let them cool completely in the pan before slicing into 16 squares.

Tips for Perfect Cinnamon Swirl Bars

Don’t overbake! The blondies should be soft in the center when you pull them out; they’ll continue to set as they cool.
For an extra gooey texture, check them around the 25-minute mark.
Swirling the top layer not only looks beautiful but ensures that cinnamon-sugar goodness in every bite.
If you prefer a thicker bar, you can bake these in a 7×7-inch pan and add an extra 3-5 minutes to the baking time.
These blondies taste amazing the next day as the flavors meld together even more—if they last that long!

A Little Story: The Blondie That Became a Family Favourite

I originally whipped up these Cinnamon Swirl Snickerdoodle Blondies on a whim for a weekend family movie night. I wanted something cozy, but not as time-consuming as rolling out a batch of cookies. Well, let’s just say… they never even made it to the movie. Warm out of the oven, with that golden cinnamon crust on top, they were gone in minutes.

Now, they’ve become a family-requested favorite—especially during the fall when everyone’s craving that cinnamon-sugar hug in dessert form. It’s the kind of recipe that feels like home, but with just enough flair to impress at potlucks and bake sales.

Serving Ideas for Snickerdoodle Blondies

These blondies are fabulous straight out of the pan, but if you’re in the mood to dress them up, here are a few ideas:

Top with a light dusting of powdered sugar for extra prettiness.
Serve warm with a scoop of vanilla ice cream and a drizzle of caramel sauce for a decadent dessert.
Pair them with a steaming mug of chai or your favorite coffee for a cozy afternoon treat.

How to Store & Freeze Blondies

Keep any leftover blondies (if you’re lucky enough to have them) in an airtight container at room temperature for up to 3 days. They’ll stay soft and chewy without any fuss.

Want to save some for later? These blondies freeze beautifully. Wrap them tightly in plastic wrap and store in a freezer-safe bag for up to 2 months. Thaw at room temperature or give them a quick zap in the microwave for that fresh-baked feel.

Frequently Asked Questions

Can I double this recipe for a larger crowd?

Absolutely! Double the ingredients and bake in a 9×13-inch pan. You may need to extend the baking time by 5-7 minutes—just keep an eye on those golden edges.

Can I add mix-ins like white chocolate chips or nuts?

Yes! White chocolate chips, chopped pecans, or even a swirl of cream cheese would be delicious additions. Just don’t go too heavy, so you don’t lose that classic snickerdoodle texture.

Do these blondies need to be refrigerated?

Nope. They’re best stored at room temperature in an airtight container to maintain their soft texture. If you’ve added cream cheese or a perishable topping, then refrigerate accordingly.

What makes these different from regular blondies?

The cinnamon-sugar swirl! It infuses every bite with that classic snickerdoodle flavor while keeping the bars dense, chewy, and buttery like a good blondie should be.
