The Story Behind This Classic Recipe
This recipe is a happy accident from my childhood. My grandma was famous for her snickerdoodles, but one day we were out of cream of tartar.
She decided to pivot and pour the cookie dough into a pan. The result was a chewy, gooey bar that was an instant family legend. We’ve been making them this way ever since, a true homemade classic.
What Makes This the *Traditional* Way
I’m a firm believer that you don’t need fancy ingredients for real comfort food. The magic here is in the method and the simplicity.
We use melted butter for that chewy, dense texture blondies are known for. No creaming butter and sugar for ages! The generous swirl of cinnamon sugar is what makes it truly special and nostalgic.

How to Make It Just Like Grandma Did
Don’t be intimidated! This is one of the easiest baking recipes you’ll ever try. Just follow these simple steps.
- First, preheat your oven to 350°F (175°C). Grease an 8×8 inch baking pan and line it with parchment paper, leaving some overhang for easy removal. This is my favorite trick!
- In a medium bowl, whisk together the melted butter and brown sugar until it’s smooth. Then, beat in the egg and vanilla extract. It will look glossy and wonderful.
- Gently fold in the flour and salt until just combined. Be careful not to overmix! A few streaks of flour are totally fine.
- Now, spread about two-thirds of the blondie batter into your prepared pan. It will be a thin layer, and that’s perfect.
- Sprinkle almost all of your cinnamon sugar mixture evenly over this first layer. Reserve about a tablespoon for the top.
- Dollop the remaining blondie batter over the cinnamon sugar. Then, take a knife and gently swirl it all together to create a marbled effect. Have fun with this part!
- Finish by sprinkling that last tablespoon of cinnamon sugar right on top. This gives you that deliciously crunchy crust.
- Bake for 25-30 minutes, or until the edges are golden and the center is just set. A toothpick inserted should come out with a few moist crumbs, not wet batter.
- Let the pan cool completely on a wire rack before you slice into squares. I know, the waiting is the hardest part!
My Tips for Perfecting This Classic
A couple of little secrets to make sure yours turn out perfectly every single time. These are my tried-and-true methods.
First, for the chewiest texture, don’t over-bake them. They will continue to set as they cool in the pan. Second, always use a light-colored metal pan. Dark pans can cause the edges to burn before the center is done.
How to Store and Enjoy Later
If they last long enough to be stored, that is! These blondies are best friends with a glass of cold milk.
Store them in an airtight container at room temperature for up to 4 days. They also freeze beautifully for up to 3 months. Just wrap them tightly in plastic wrap and then foil.

Your Questions About This Classic Recipe
I get asked these questions all the time. Hopefully, this clears things up for you!
Can I make these blondies ahead of time?
Absolutely! In fact, I think they taste even better the next day. The flavors have more time to meld together, making them even more delicious.
My center sunk a little. What happened?
Don’t worry, they’ll still taste amazing! This usually means they could have used just a minute or two more in the oven. The center continues to cook from residual heat as it cools.
Can I add nuts or chocolate chips?
You bet! This is a wonderfully adaptable recipe. Feel free to stir in a half-cup of chopped walnuts or semi-sweet chocolate chips into the batter for a fun twist.
I truly hope this recipe finds its way into your regular rotation of sweet treats. It’s a little piece of my family’s history that I’m so happy to share with yours.
