Ingredients for Your Sweet Fall Treat

Gather these simple ingredients. The magic is in how you combine them.

• 1 cup (2 sticks / 226g) unsalted butter
• 2 cups (400g) packed light brown sugar
• 2 large eggs, at room temperature
• 1 tablespoon pure vanilla extract
• 2 cups (250g) all-purpose flour
• 1 teaspoon baking powder
• 1/2 teaspoon salt
• For the Cinnamon Sugar Swirl:
• 1/4 cup (50g) granulated sugar
• 1 tablespoon ground cinnamon

A note on the butter: Using unsalted butter lets you control the salt level. If you only have salted, just reduce the added salt in the recipe to 1/4 teaspoon. Melting it is key for the dense, fudgy texture that makes this easy cinnamon sugar blondies – sweet fall treat so special.

One easy substitution: Out of light brown sugar? Dark brown sugar will work beautifully and give an even deeper, almost molasses-like flavor. Your kitchen will smell incredible.

How to Make These Easy Cinnamon Sugar Blondies

Follow these simple steps for perfect results every time. Preheat your oven to 350°F (175°C). Line a 9×13 inch baking pan with parchment paper, leaving an overhang on two sides for easy lifting later. This little trick is a game-changer for clean cuts.

1. Brown the butter (for flavor!). Melt the butter in a medium saucepan over medium heat. Let it cook, swirling the pan occasionally, until it turns a deep golden color and smells nutty. This takes about 5-7 minutes. Pour it immediately into a large mixing bowl to stop the cooking. That toasted flavor is the secret weapon.
2. Let the brown butter cool for just 5 minutes. Then, whisk in the packed brown sugar until it’s completely smooth and no lumps remain. The mixture will look glossy. This is the foundation of your easy cinnamon sugar blondies – sweet fall treat, so take your time here.
3. Whisk in the eggs, one at a time, making sure each is fully incorporated before adding the next. Then, stir in the vanilla extract. The batter will thicken slightly and become paler in color.
4. Add the dry ingredients. In a separate bowl, whisk together the flour, baking powder, and salt. Add this to the wet ingredients and use a spatula to fold it in gently. Mix just until the last streaks of flour disappear. Over-mixing leads to tough blondies, and we want them tender.
5. In a small bowl, mix the 1/4 cup granulated sugar and 1 tablespoon of cinnamon for the swirl. Pour about two-thirds of your blondie batter into the prepared pan and spread it into an even layer. Sprinkle about two-thirds of the cinnamon sugar mixture evenly over the top. Dollop the remaining batter over the cinnamon sugar—don’t worry about covering it completely. Use a knife or a skewer to gently swirl the batters together. Then, sprinkle the remaining cinnamon sugar over the very top. This double layer creates that beautiful marbled look and ensures every bite of your easy cinnamon sugar blondies – sweet fall treat has that spicy-sweet kick.
6. Bake for 25-30 minutes. The top will be golden brown, set, and beautifully crackled. A toothpick inserted into the center should come out with a few moist crumbs attached, not wet batter. That’s your cue. They’ll continue to set as they cool. The smell will be absolutely irresistible.
7. The hardest part: let them cool. Let the pan cool completely on a wire rack—at least an hour. I know, it’s torture. But cutting into warm blondies makes a mess. Once cool, use the parchment paper overhang to lift the entire slab out of the pan onto a cutting board. Slice into squares with a sharp knife.

Tips, Tricks, and Fun Variations

Storage is simple. Keep these easy cinnamon sugar blondies in an airtight container at room temperature for up to 4 days. They actually get chewier and more flavorful on day two. For longer storage, you can freeze them for up to 3 months. Just thaw at room temperature.

For clean cuts, wipe your knife clean between each slice. It makes a huge difference in getting those picture-perfect squares. A plastic knife also works surprisingly well for cutting bar cookies without dragging.

Make them your own. Stir 1/2 cup of chopped toasted pecans or walnuts into the batter with the flour. For a chocolatey twist, fold in 3/4 cup of white chocolate chips or butterscotch chips. You could even add a teaspoon of apple pie spice to the cinnamon sugar for an extra-autumnal vibe. This recipe is wonderfully adaptable.

Want to make them ahead? You can mix the dry ingredients and the cinnamon sugar the night before. In the morning, just melt the butter and you’re minutes away from fresh-baked bliss. It’s the ultimate easy cinnamon sugar blondies – sweet fall treat for a busy weekend.
