Ingredients Notes

The beauty of these blondies lies in their simple ingredients, each bringing its own magic to the recipe. Here’s a look at what you’ll need:

Butter: For the best flavor and texture, use real unsalted butter. It gives these blondies a rich, buttery base that’s unbeatable. Melted butter makes mixing easy and ensures a chewy texture.
Brown Sugar: Brown sugar is the key to these blondies' deep, caramel-like sweetness and chewy texture. You can use either light or dark brown sugar – dark will add a bit more richness.
Cinnamon: This star ingredient brings warmth and a hint of spice to the blondies. If you’re a cinnamon lover, feel free to increase the amount slightly for an extra cozy flavor.
Vanilla Extract: A touch of vanilla enhances the sweetness and depth of the blondies, making them even more irresistible.
All-Purpose Flour: Regular all-purpose flour gives these blondies structure without being too dense. For a gluten-free version, substitute with a 1:1 gluten-free flour blend.

Optional: A sprinkle of granulated sugar and cinnamon on top creates a slight crunch and an extra layer of cinnamon flavor. It’s a quick step that adds a special touch to the blondies.

No special equipment is required! Just a mixing bowl, a whisk, and a 9x13-inch baking pan will do the job perfectly.

How To Make These Cinnamon Sugar Blondies

Making these cinnamon sugar blondies couldn’t be simpler. Follow these easy steps, and you’ll have a batch ready to enjoy in no time.

Preheat the oven to 350°F (175°C) and lightly grease a 9x13-inch baking pan or line it with parchment paper for easy removal.
In a large mixing bowl, melt the butter and let it cool slightly. Then, whisk in the brown sugar until smooth and glossy. This step gives the blondies their fudgy texture, so don’t skip it!
Add the eggs one at a time, whisking well after each addition. Stir in the vanilla extract to combine.
In a separate bowl, mix the flour, baking powder, salt, and cinnamon. Gradually fold the dry ingredients into the wet mixture until just combined. Overmixing can lead to tough blondies, so mix gently.
Spread the batter evenly into the prepared baking pan. For a classic touch, sprinkle a mixture of cinnamon and sugar on top. This will bake into a lightly crunchy, fragrant crust.
Bake for 20-25 minutes, or until the edges are golden and a toothpick inserted into the center comes out with just a few moist crumbs. Be careful not to overbake, as you want the center to stay soft and chewy.

Let the blondies cool completely in the pan before slicing. They’re delicious warm or at room temperature, with each square offering a gooey, buttery bite with a hint of cinnamon.

Storage Options

These cinnamon sugar blondies are fantastic for storing, making them even more convenient.

Room Temperature: Store the blondies in an airtight container at room temperature for up to 4 days. They’ll stay chewy and delicious, with the cinnamon flavor mellowing over time.
Refrigerator: If you prefer a slightly firmer texture, store them in the fridge. Place them in an airtight container, and they’ll last for about a week.
Freezer: These blondies freeze beautifully! Wrap individual squares in plastic wrap, then place them in a freezer-safe bag. They’ll keep well for up to 3 months. Just thaw at room temperature when you’re ready to enjoy.

To reheat, pop a square in the microwave for about 10 seconds to restore that soft, fresh-baked warmth.

Variations and Substitutions

This recipe is wonderfully versatile, so feel free to make it your own. Here are some delicious ideas:

Add Chocolate Chips: Sprinkle in white, milk, or dark chocolate chips for a sweeter, richer taste.
Nuts for Crunch: Walnuts, pecans, or almonds add a delightful crunch and depth of flavor to the blondies.
Swirl in Caramel or Nutella: Drizzle some caramel or Nutella over the batter and swirl it through before baking for a gooey, indulgent twist.
Pumpkin Spice: For a fall-inspired version, replace some of the cinnamon with pumpkin spice blend. The warm spices pair perfectly with the brown sugar.
Make it Gluten-Free: Substitute all-purpose flour with a 1:1 gluten-free flour blend, and you’ll have blondies that everyone can enjoy.

No matter which variation you choose, these blondies will always hit the spot. Feel free to experiment and find your favorite version!
