Cinnamon Sugar Blondies
The first time I made blondies, I pulled them out too early and ended up with a gooey, underbaked mess. That failure taught me exactly what to look for – and now after testing this recipe 15+ times, I’ve nailed the perfect chewy texture every single time.
These cinnamon sugar blondies have crisp, crackly tops with dense, fudgy centers that taste like a cross between a snickerdoodle and a brownie. They come together in one bowl, no mixer needed, and bake in under 30 minutes.
Step-by-Step Instructions
Step 1: Brown the Butter
Melt 1/2 cup (113g) of butter in a light-colored saucepan over medium heat, stirring constantly. You’ll hear it sizzle, then go quiet – that silence means the water is evaporating and the magic is about to happen.
Watch for golden bits forming at the bottom and a nutty, almost caramel smell hitting the air. Pull it off heat immediately at that point – I’ve burned it twice by waiting “just one more minute.”
Step 2: Mix Butter and Sugar
Pour the browned butter into a large mixing bowl and add 1 cup (200g) of packed light brown sugar. Whisk vigorously for about 90 seconds until the mixture looks glossy and slightly thickened.
This step matters more than it seems. I tested it with and without thorough whisking – the whisked version had that beautiful crackly top, while the lazy mix produced flat, dull blondies. The friction dissolves the sugar crystals and adds structure.
Step 3: Add Egg and Vanilla
Crack 1 large egg plus 1 egg yolk into the cooled butter mixture – make sure it’s below 130°F or you’ll scramble the egg. Add 1.5 teaspoons of pure vanilla extract and whisk until the batter looks pale, thick, and ribbony.
The extra yolk was a game-changer I discovered on my 8th test batch. It adds richness and makes the center fudgier without making the blondie greasy. Don’t skip it.
Step 4: Mix the Dry Ingredients
In a separate small bowl, whisk together 1 cup (125g) all-purpose flour, 1.5 teaspoons cinnamon, 1/4 teaspoon baking powder, and 1/2 teaspoon salt. The smell when you mix these spices together is incredible – warm, sweet, and bakery-worthy.
Measure flour using the spoon-and-level method, not scooping directly from the bag. Over-packing flour is the number one reason blondies turn out cakey instead of chewy. I learned that the hard way on batch three.

Step 5: Combine Wet and Dry
Fold the flour mixture into the wet ingredients using a rubber spatula, not a whisk. Stop the moment you no longer see dry streaks – overmixing develops gluten and makes blondies tough and chewy in a bad way.
The batter will be thick and sticky, almost like a soft cookie dough. That’s exactly what you want. If it looks too wet or loose, your butter wasn’t cooled enough before adding the egg.
Step 6: Pan Prep and Cinnamon Sugar Topping
Line an 8×8-inch baking pan with parchment paper, leaving overhang on two sides for easy lifting. Spread the batter evenly using an offset spatula – it takes some patience because the batter resists spreading.
Mix 2 tablespoons granulated sugar with 1/2 teaspoon cinnamon in a small bowl and sprinkle generously over the top. This topping creates that gorgeous crackly, sparkly crust that makes these blondies look bakery-level beautiful.
Step 7: Bake and Cool
Bake at 350°F (175°C) for 22-25 minutes. The edges should look set and pull slightly from the pan sides, while the center still has a very slight jiggle when you shake the pan gently.
Don’t overbake – I did that on batch five and ended up with dry, crumbly bars. A toothpick inserted at the center should come out with moist crumbs, not clean. Let them cool completely in the pan, about 45 minutes, before cutting.

1.5 tsp ground cinnamon
1/4 tsp baking powder
1/2 tsp salt
2 tbsp granulated sugar (for topping)
1/2 tsp cinnamon (for topping)
Directions
- Preheat oven to 350°F. Line an 8×8-inch pan with parchment paper.
- Brown butter in a saucepan over medium heat until golden and nutty smelling. Cool 10 minutes.
- Whisk brown sugar into cooled brown butter for 90 seconds until glossy.
- Add egg, egg yolk, and vanilla. Whisk until pale and ribbony.
- In a separate bowl, combine flour, cinnamon, baking powder, and salt.
- Fold dry ingredients into wet ingredients until just combined.
- Spread batter into prepared pan. Mix topping sugar and cinnamon, sprinkle over batter.
- Bake 22-25 minutes until edges are set and center has a slight jiggle. Cool fully before cutting.
Notes
- Store in an airtight container at room temperature up to 4 days.
Substitute half the flour with almond flour for a nuttier, denser bar.
Batter can be made ahead and refrigerated up to 24 hours before baking.
For extra indulgence, fold in 1/2 cup white chocolate chips before baking.

What Makes Blondies Chewy Instead of Cakey?
The chewiness in blondies comes from two things: brown sugar and the ratio of fat to flour. Brown sugar contains molasses, which is hygroscopic – it pulls moisture from the air and keeps bars soft longer.
I tested this recipe with all granulated sugar once, and the result was noticeably cakier and drier. The molasses in brown sugar genuinely makes a measurable difference you can taste and feel in the texture.
Using melted butter instead of creamed butter also plays a huge role. Creamed butter traps air, which creates lift and a cakey texture. Melted butter skips that air incorporation entirely.
The extra egg yolk adds fat without extra water, which further promotes that dense, fudgy chew. Removing it produced bars that were slightly lighter – good, but not as satisfying.
Can You Add Mix-Ins to Cinnamon Sugar Blondies?
Absolutely – these blondies take mix-ins beautifully. White chocolate chips are my personal favorite addition, about 1/2 cup folded into the batter just before spreading. The sweetness balances the warm spice perfectly.
Toasted pecans or walnuts (1/3 cup, roughly chopped) add great crunch and pair naturally with cinnamon. I tested both and prefer pecans – they’re softer and don’t compete with the chewy texture.
Butterscotch chips or toffee bits also work wonderfully here. Just keep total mix-ins under 3/4 cup total or the batter gets too heavy and the bars don’t bake evenly through the center.
How Do You Know When Blondies Are Done Baking?
Blondies are notoriously hard to read because they don’t rise dramatically like cake. The best visual cue is the edges: they should look matte, set, and just barely starting to pull from the pan sides.
The center should look slightly underdone when you pull them – that’s intentional. They continue cooking from residual heat for about 10 minutes after leaving the oven. I ruined two batches by leaving them in until the center looked “done.”
Use the toothpick test as your backup check. Insert it 1 inch from the center – moist crumbs clinging to the toothpick means they’re perfect. A clean toothpick means you’ve gone 3-4 minutes too far.
How Should You Store Cinnamon Sugar Blondies?
Store cooled blondies in an airtight container at room temperature for up to 4 days. Layer them between sheets of parchment paper if stacking to protect that cinnamon sugar crust on top.
I tested refrigerating them and honestly don’t recommend it. The cold hardens the butter and makes the texture dense and waxy rather than soft and chewy. Room temperature is always better for bar cookies with high fat content.
For longer storage, freeze cut blondies individually wrapped in plastic wrap, then placed in a zip-lock bag. They thaw at room temperature in about 30 minutes and taste just as fresh as day one.
Can You Make Blondies Ahead of Time?
Yes, and they actually taste better on day two. The cinnamon flavor deepens and the texture settles into an even chewier consistency overnight. I always bake these the day before I need them for that reason.
You can also refrigerate the unbaked batter in the pan, covered tightly, for up to 24 hours before baking. Pull it out 20 minutes before baking to take the chill off – cold batter straight from the fridge bakes unevenly.
Frequently Asked Questions
Q: Why did my blondies turn out cakey?
A: Cakey blondies usually mean too much flour or over-mixing. Spoon flour into the measuring cup and level it off – never scoop directly from the bag.
Q: Can I double this blondie recipe?
A: Yes – double all ingredients and bake in a 9×13-inch pan at 350°F. Add 5-7 extra minutes to the bake time and start checking at the 28-minute mark.
Use the same toothpick test: moist crumbs mean done, clean toothpick means overbaked. The larger pan bakes slightly slower in the center.
Q: Can I use salted butter instead of unsalted?
A: You can, but reduce the added salt in the recipe to 1/4 teaspoon instead of 1/2 teaspoon. The flavor balance stays right without going overly salty.
Salted butter brands vary widely in sodium content, so results may differ slightly. Unsalted butter gives you more consistent, predictable control over the final flavor.
