Ingredients

Scale

For the Blondie Base:

1 cup (226g) unsalted butter, melted
1 cup (200g) light brown sugar, packed
1/2 cup (100g) granulated sugar
2 large eggs
1 tablespoon vanilla extract
2 1/4 cups (281g) all-purpose flour
1/2 teaspoon baking powder
1/2 teaspoon salt
1 1/2 teaspoons ground cinnamon

For the Cinnamon Swirl:

2 tablespoons granulated sugar
1 teaspoon ground cinnamon

Instructions

Preheat and Prep: Preheat your oven to 350°F (175°C). Grease or line a 9×13-inch baking pan with parchment paper to ensure easy removal of the blondies once baked and cooled.
Mix the Blondie Batter: In a large bowl, whisk together the melted butter, light brown sugar, and granulated sugar until smooth and glossy. Add the eggs and vanilla extract, whisking again until the mixture is well combined and slightly lightened in color.
Add the Dry Ingredients: Sprinkle in the all-purpose flour, baking powder, salt, and ground cinnamon. Fold the dry ingredients gently into the wet mixture using a spatula or wooden spoon until no flour streaks remain, being careful not to overmix.
Layer and Swirl: Pour the batter evenly into the prepared pan and smooth the top. In a small bowl, mix the cinnamon and sugar for the swirl. Sprinkle this cinnamon-sugar mixture evenly over the batter, then use a knife or toothpick to gently swirl it into the surface, creating rustic patterns.
Bake: Place the pan in the preheated oven and bake for 25–30 minutes, or until the edges are set and a toothpick inserted into the center comes out with a few moist crumbs.
Cool and Slice: Allow the blondies to cool completely in the pan to set properly. Once cooled, lift out using the parchment paper and slice into 20 squares for serving.

Notes

Do not overbake; the center may seem slightly soft but will firm up upon cooling.
Using parchment paper helps with easy removal and clean slicing.
Enhance the cinnamon flavor by adding a pinch more cinnamon to the batter or swirl mixture.
Optional: Add white chocolate chips or a dash of nutmeg for variation.
