Ingredients Notes

The magic of these Cinnamon Sugar Blondies comes from a few key ingredients that give them their unique flavor and texture. Each ingredient has its place in creating a blondie that’s chewy, buttery, and spiced to perfection.

Butter: Start with melted butter for that rich, caramel-like base flavor in your blondies. Using melted butter also helps make the blondies extra chewy and moist.
Brown Sugar: This is essential for the blondies' sweetness and slightly caramelized flavor. I recommend dark brown sugar for a deeper taste, but light brown sugar will also work if that’s what you have on hand.
Cinnamon: Cinnamon brings warmth and aroma that makes these blondies taste like a cinnamon roll in bar form. Don’t skimp on it – it’s what gives the blondies their signature flavor.
All-Purpose Flour: This forms the base of your blondies, creating structure without weighing them down. Be sure to measure carefully to keep them chewy and soft.
Egg: Just one egg is all you need to bind everything together and add richness to the blondies.

For this recipe, no special equipment is necessary – just a mixing bowl, spatula, and an 8x8-inch baking pan lined with parchment paper for easy removal.

How to Make Cinnamon Sugar Blondies

Making these Cinnamon Sugar Blondies is so easy, you’ll find yourself coming back to this recipe over and over. Here’s a step-by-step guide to ensure they turn out perfect every time.

Prepare your pan. Preheat your oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper, leaving a bit of overhang on the sides. This will make it easy to lift out the blondies once they’re done.
Mix the wet ingredients. In a large mixing bowl, combine the melted butter and brown sugar. Whisk until smooth and well-blended, about 1-2 minutes. Add in the egg and mix until it’s fully incorporated.
Add the dry ingredients. Gently fold in the flour and cinnamon. Mix just until the dry ingredients are fully incorporated – be careful not to overmix, as this can make the blondies tough instead of chewy.
Spread and top with cinnamon sugar. Pour the batter into your prepared pan and spread it evenly. In a small bowl, combine a bit more cinnamon and granulated sugar, then sprinkle this cinnamon sugar mixture evenly over the top of the blondie batter. This will create a delicious, slightly crunchy topping.
Bake. Bake for 20-25 minutes, or until the edges are golden and a toothpick inserted into the center comes out mostly clean. Let the blondies cool in the pan for at least 15 minutes before lifting them out and cutting into squares.

These blondies bake quickly, so keep an eye on them as they near the end of their baking time to avoid overbaking.

Storage Options

One of the best things about Cinnamon Sugar Blondies is that they store well, making them perfect for preparing ahead of time or enjoying leftovers.

Room Temperature: Store your blondies in an airtight container at room temperature for up to 3 days. They’ll stay chewy and delicious without needing refrigeration.
Refrigeration: If you prefer a firmer blondie or want to keep them fresh a bit longer, store them in the fridge. They’ll keep well for up to a week in an airtight container.
Freezing: These blondies also freeze beautifully. Wrap each square individually in plastic wrap, then place them in a freezer-safe bag. They’ll keep for up to 2 months. Just thaw them at room temperature or pop one in the microwave for a quick treat.

To reheat, a quick 10-second zap in the microwave will bring back that freshly baked warmth and softness.

Variations and Substitutions

One of the best things about Cinnamon Sugar Blondies is how adaptable they are. Here are a few variations to make them your own:

Add chocolate chips: A handful of chocolate or white chocolate chips folded into the batter adds a sweet, melty surprise in each bite.
Try different spices: Experiment with nutmeg or cardamom for a different flavor profile that still complements the cinnamon.
Make them gluten-free: Substitute the all-purpose flour with a 1:1 gluten-free baking flour blend. This keeps the blondies chewy without compromising texture.
Nuts or dried fruit: Add chopped walnuts, pecans, or even dried cranberries for an extra layer of texture and flavor.
Vanilla drizzle: For a sweeter touch, drizzle the top of the cooled blondies with a simple vanilla icing made from powdered sugar, vanilla extract, and milk.

The possibilities are endless, so don’t be afraid to get creative with your blondies and make them your own!

These Cinnamon Sugar Blondies are sure to become a favorite with family and friends. Whether you're baking for a gathering or simply craving something sweet, these blondies are guaranteed to hit the spot.
