I stumbled onto these cinnamon sugar blondies completely by accident three falls ago. Oliver and I were making regular blondies when he knocked over the cinnamon sugar we'd been using for toast, and it spilled all over the unbaked batter. I almost started over, but we were running late for his soccer game, so I just spread it around and threw the pan in the oven. Best mistake ever. That crunchy cinnamon sugar blondies topping combined with the chewy, buttery blondie underneath created something I've been making at least twice a month ever since.

Why You'll Love These Cinnamon Blondies
Back making these for every fall bake sale, potluck, and random Tuesday night for the past three years, I can tell you exactly why these work. They come together in one bowl in about 10 minutes - I'm talking from getting ingredients out to sliding the pan in the oven. No stand mixer to drag out and clean, no complicated steps, just melted butter and a wooden spoon. Oliver can make these by himself now (with oven supervision), which tells you how simple they really are.
The texture is what gets people. That cinnamon sugar blondies topping creates this thin, crackly crust that gives way to a chewy, almost fudgy center. They're denser than cake but not as heavy as brownies - right in that perfect middle spot. I've brought these to parties where people who don't even like blondies end up eating three squares. My neighbor Kate asked for the recipe five times before I finally wrote it down for her because she kept losing the napkin I'd scribbled it on.

How To Make Cinnamon Sugar Blondies Step By Step
Mix the Blondie Batter

- Pour melted butter into large bowl with brown sugar
- Stir together until well combined and slightly grainy looking
- Crack in eggs one at a time, mixing well after each one
- Add vanilla extract and stir until smooth
- Dump in flour, baking powder, and salt all at once
- Fold gently with wooden spoon just until no dry flour shows

Prep Your Pan and Add Magic Topping
- Line 9x13 pan with parchment paper or grease really well with butter
- Pour batter into pan and spread evenly with spatula
- Mix cinnamon and sugar together in small bowl
- Sprinkle cinnamon sugar generously over entire top of batter
- Use all of it - don't be shy here
Bake to Chewy Perfection
- Let cool in pan on wire rack for at least 20 minutes before cutting
- Slide pan into preheated 350°F oven on middle rack
- Bake for 22-25 minutes until edges look set and top is crackly
- Center should still look slightly underdone - this is important
- Toothpick inserted in center should come out with a few moist crumbs
Smart Swaps for Cinnamon Sugar Blondies
Sugar Options:
- Light brown sugar → Dark brown sugar (deeper molasses flavor)
- Brown sugar → Half white, half brown (less chewy but works)
- Regular sugar → Coconut sugar (slightly different taste, less sweet)
Flour Choices:
- All-purpose flour → Gluten-free 1-to-1 blend (add ¼ teaspoon xanthan gum if not included)
- White flour → Whole wheat pastry flour (denser texture, nuttier taste)
- Regular flour → Almond flour (doesn't work well, too crumbly)
Butter Alternatives:
- Unsalted butter → Salted butter (skip the added salt in recipe)
- Regular butter → Coconut oil (slightly different texture, coconut taste)
- Dairy butter → Vegan butter sticks (Earth Balance works best)
Egg Swaps:

Flavor Twists:
- Regular topping → Brown sugar cinnamon mix (richer taste)
- Vanilla extract → Maple extract (fall vibes)

Top Tip
- They'd pull the pan out halfway through baking, give it one hard slam on the counter, then put it right back in the oven. Sounds weird, right? But what happens is all those air bubbles that formed get knocked out, and the batter settles into this denser, chewier texture. The slam also helps the edges pull away slightly from the pan, which creates those crispier corners everyone fights over.
- First time I tried it with these cinnamon sugar blondies, I was nervous about ruining the cinnamon sugar blondies topping. But it works perfectly - the topping stays put and actually seems to sink in just a tiny bit, making the flavor go deeper into the blondie. Now I set a timer for 12 minutes, pull the pan out, give it a good slam on the counter (Oliver loves doing this part), and slide it back in for the remaining time.
- Lisa also taught me to underbake them slightly. She'd say "If it looks done, it's overdone." The center should still jiggle just a little when you shake the pan. They firm up as they cool, and you end up with that perfect chewy texture instead of a dry cake-like bar. Takes some practice to trust it, but once you nail the timing, you'll never want blondies any other way.
FAQ
How to know when blondies are done baking?
The edges should look set and slightly pulled away from the pan, while the center still jiggles just a tiny bit when you shake it. A toothpick stuck in the middle should come out with moist crumbs, not wet batter but definitely not clean. I pull mine at 23 minutes usually. They'll keep cooking in the hot pan after you take them out.
What is a dirty blondie?
A dirty blondie is when you swirl brownie batter into blondie batter before baking, creating a marbled effect. Some bakeries also call them "brookies" when they add chocolate chips or Oreo pieces. It's basically a hybrid dessert bar. Not the same as these cinnamon sugar cinnamon sugar blondies , but the technique works if you want to get creative with mix-ins.
How long is cinnamon sugar blondies good for?
Cinnamon sugar lasts pretty much forever in an airtight container at room temperature. The sugar keeps the cinnamon from clumping and going stale. I've had the same jar in my pantry for over a year and it's still fine. Just give it a quick stir before using since the cinnamon can settle to the bottom over time.
How long do homemade cinnamon sugar blondies last?
These stay good on the counter in an airtight container for about 5-7 days. They actually taste better on day two after the flavors settle. Don't refrigerate them unless your kitchen is super hot - cold temps make them hard and dry. For longer storage, freeze individual wrapped squares for up to three months and thaw at room temperature when you want one.
