Cinnamon Swirl Snickerdoodle Blondies

There’s something incredibly nostalgic about the smell of cinnamon drifting through the kitchen. It brings you back to cozy autumn afternoons, family get-togethers, and that comforting feeling of home. These Cinnamon Swirl Snickerdoodle Blondies are like the cookie version of your favorite warm hug—a perfect marriage between soft, chewy blondies and the sweet-spicy charm of snickerdoodles.

I remember the first time I baked these for a fall potluck. They disappeared within minutes, and I ended up scribbling the recipe on napkins for everyone who asked. Since then, they’ve become a go-to treat—not just for holidays but for anytime I want to bring a little joy to the table. Whether it’s the golden crackly top, the rich cinnamon sugar swirl, or the buttery-soft texture, these bars are simply irresistible.

What makes these blondies special is that classic snickerdoodle essence—that perfect balance of sweet and spice—baked into a dense, fudgy bar form. No scooping, chilling, or rolling dough required. Just mix, swirl, bake, and enjoy!

• 1 cup (200g) light brown sugar, packed
• 1/2 cup (100g) granulated sugar
• 2 large eggs
• 1 tablespoon vanilla extract
• 2 1/4 cups (281g) all-purpose flour

HOW TO MAKE CINNAMON SWIRL SNICKERDOODLE BLONDIES:

STEP-BY-STEP INSTRUCTIONS:

Step 1: Preheat and Prep Start by preheating your oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper. This helps the bars lift out easily once they’re baked and cooled.

Step 2: Mix the Blondie Batter In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth and glossy. This base gives the blondies their signature chewy texture.

Next, add in the eggs and vanilla extract. Whisk again until everything is well combined and the mixture lightens in color just slightly.

Step 3: Add the Dry Ingredients Sprinkle in the flour, baking powder, salt, and ground cinnamon. Using a spatula or wooden spoon, gently fold the dry ingredients into the wet mixture until no streaks of flour remain. Be careful not to overmix—the goal is a smooth, thick batter.

Step 4: Layer and Swirl Pour the batter into your prepared pan and smooth the top. In a small bowl, mix together the cinnamon and sugar for the swirl.

Sprinkle the cinnamon-sugar mixture evenly over the top of the blondie batter. Then, using a knife or toothpick, gently swirl it into the surface. It doesn’t need to be perfect—the rustic swirls make these bars extra charming!

Step 5: Bake Slide the pan into your preheated oven and bake for about 25–30 minutes, or until the edges are set and a toothpick inserted into the center comes out with just a few moist crumbs.

Step 6: Cool and Slice Let the blondies cool completely in the pan before slicing. This helps them set up and makes them easier to cut into clean squares.

HELPFUL TIPS:

• Don’t overbake! The center might look slightly soft when you take it out, but it will firm up as it cools.
• Line your pan: Parchment paper makes it easier to lift the whole batch out for clean slicing.
• Spice it up: If you love a strong cinnamon flavor, feel free to add a pinch more to the batter or swirl mix.
• Make it your own: Add a handful of white chocolate chips or a pinch of nutmeg for a little twist.

FREQUENTLY ASKED QUESTIONS:

Can I use dark brown sugar instead of light?
Yes! Dark brown sugar will add a deeper molasses flavor, which pairs beautifully with the cinnamon.

Can I make these ahead of time?
Absolutely. These blondies actually taste even better the next day and keep well in an airtight container for up to 5 days.

Can I freeze them?
Yes, just let them cool completely, wrap tightly, and freeze for up to 2 months. Thaw at room temp before enjoying.

Can I use gluten-free flour?
Yes, a 1:1 gluten-free baking blend should work just fine—just check that it contains xanthan gum.

STORAGE INSTRUCTIONS:

Store blondies in an airtight container at room temperature for up to 5 days. For longer storage, wrap individually and freeze for up to 2 months. Let thaw before serving or warm slightly in the microwave for that fresh-baked feel.
