Ingredients Notes

Creating these Cinnamon Sugar Blondies is all about using simple ingredients to make something truly special. Here’s a closer look at what goes into these delicious bars and why each ingredient matters.

Butter: The base of these blondies, butter brings a rich flavor that perfectly complements the cinnamon and sugar. Make sure it’s melted and slightly cooled so it blends well with the other ingredients.
Brown Sugar: This adds a depth of flavor and helps create the chewy, soft texture we love in blondies. If you want extra caramel notes, use dark brown sugar.
Granulated Sugar: Used in the cinnamon-sugar topping, granulated sugar creates that classic crackly crust on top. The contrast between the fudgy blondie and the crisp topping is what makes these bars so addictive.
Cinnamon: The star of the show! Adding cinnamon both in the batter and on top creates a warm, inviting flavor throughout. Feel free to adjust the amount if you prefer a stronger or milder cinnamon taste.
Flour: All-purpose flour works best here, giving the blondies structure while keeping them tender. Just be sure not to overmix once you add the flour to avoid tough blondies.
Eggs: Eggs provide richness and bind the ingredients together, adding to the chewy texture. Use room-temperature eggs for the best results.

If you have it, a parchment-lined baking dish will make removing and cutting these bars a breeze. It’s not essential, but it’s a game-changer for easy cleanup!

How To Make Cinnamon Sugar Blondies

Making these Cinnamon Sugar Blondies couldn’t be easier! Let me guide you through the process to ensure they come out perfectly every time.

Preheat and Prep: Begin by preheating your oven to 350°F (175°C). Grease an 8x8-inch baking pan and line it with parchment paper for easy removal. This step will make a big difference in getting those perfect, clean slices.
Make the Batter: In a large bowl, whisk together the melted butter and brown sugar until smooth and creamy. Add in the egg and vanilla extract, mixing until fully incorporated. Be sure not to overmix – a few lumps are fine at this stage.
Combine Dry Ingredients: In a separate bowl, combine the flour, baking powder, and salt. Gradually add the dry mixture to the wet ingredients, stirring just until combined. The batter will be thick and sticky – that’s exactly what you want for dense, chewy blondies.
Spread and Add Topping: Pour the batter into your prepared baking pan, spreading it evenly to reach all corners. In a small bowl, mix together granulated sugar and cinnamon for the topping, then sprinkle this mixture generously over the batter. It will create that iconic crackly crust once baked.
Bake to Perfection: Place the pan in the preheated oven and bake for 20-25 minutes, or until a toothpick inserted into the center comes out with a few moist crumbs. You don’t want to overbake – they’ll continue to firm up as they cool, so a slightly underdone center is perfect.

Once baked, let the blondies cool completely in the pan before slicing. This will ensure clean, neat edges and a fully set texture.

Storage Options

These Cinnamon Sugar Blondies store beautifully, so you can enjoy them for days. Here’s how to keep them fresh and delicious:

Room Temperature: Store them in an airtight container at room temperature for up to 3 days. They’ll stay chewy and moist, especially if you keep them in a sealed container.
Refrigeration: If you want them to last a little longer, you can refrigerate the blondies for up to a week. The fridge will make them a bit firmer, so you may want to warm them slightly before eating.
Freezing: These blondies are freezer-friendly, too! Wrap individual bars in plastic wrap and place them in a freezer-safe bag or container. They’ll keep well for up to 3 months. Just let them thaw at room temperature or pop them in the microwave for a few seconds before enjoying.

Variations and Substitutions

The beauty of these Cinnamon Sugar Blondies is how easily you can customize them. Here are some fun ways to change up the recipe:

Chocolate Chips: If you’re a chocolate lover, try adding half a cup of chocolate chips to the batter. They add a nice contrast to the cinnamon flavor and make these bars extra indulgent.
Nuts: Chopped walnuts or pecans add a delightful crunch. Stir a small handful into the batter for a more textured bite.
Pumpkin Spice: For a fall-inspired twist, substitute pumpkin spice for some of the cinnamon in the topping. It brings a seasonal flavor that pairs wonderfully with the blondie base.
Brown Butter: For even more depth, try browning the butter before adding it to the batter. It brings a nutty, toasty flavor that elevates these blondies to the next level.
Gluten-Free: Substitute your favorite gluten-free flour blend to make these blondies gluten-free. Just be sure it’s a 1:1 substitute so the texture remains chewy.

However you decide to make them, these Cinnamon Sugar Blondies are sure to be a hit. Don’t be afraid to try new flavors and textures – you might just discover your own favorite twist on this classic dessert!
