Ingredients

Scale

Blondie Batter

  • 1 cup unsalted butter, melted and slightly cooled
  • 1 1/4 cups light brown sugar, packed
  • 1/2 cup granulated sugar
  • 2 large eggs, room temperature
  • 2 teaspoons vanilla extract
  • 2 1/4 cups all-purpose flour
  • 1 teaspoon cream of tartar
  • 1/2 teaspoon baking soda
  • 1/2 teaspoon salt

Cinnamon Swirl

  • 1/3 cup granulated sugar
  • 1 tablespoon ground cinnamon
  • 2 tablespoons unsalted butter, melted

Optional Topping

  • 2 tablespoons granulated sugar mixed with 1/2 teaspoon ground cinnamon

Instructions

  1. Preheat the Oven: Preheat your oven to 350°F (175°C). Grease a 9×13-inch baking dish and line it with parchment paper, leaving an overhang on the sides for easy removal of the blondies once baked.
  2. Mix the Wet Ingredients: In a large bowl, whisk together the melted butter, light brown sugar, and granulated sugar until the mixture is smooth. Add the eggs and vanilla extract, whisking thoroughly until fully incorporated, creating a thick and glossy batter base.
  3. Combine the Dry Ingredients: In a separate bowl, sift together the all-purpose flour, cream of tartar, baking soda, and salt. Gradually fold the dry ingredients into the wet ingredients, stirring gently until just combined to avoid overmixing which could result in dense blondies.
  4. Prepare the Cinnamon Swirl: In a small bowl, mix the granulated sugar and ground cinnamon. Stir in the melted butter until the mixture has a wet sand-like texture, ready to be swirled into the batter.
  5. Layer the Batter and Swirl: Spread half of the blondie batter evenly into the prepared baking dish using a spatula. Evenly sprinkle the cinnamon-sugar mixture over this layer. Dollop the remaining blondie batter over the cinnamon-sugar layer and gently spread it to cover. Use a butter knife to create decorative swirls by dragging it through the batter in a zigzag pattern.
  6. Add the Optional Topping: For added texture and cinnamon flavor, sprinkle the cinnamon-sugar topping evenly over the surface of the batter before baking, if desired.
  7. Bake: Place the baking dish in the preheated oven and bake for 30 to 35 minutes, or until the edges turn golden brown and a toothpick inserted in the center comes out with a few moist crumbs, indicating gooey but set blondies.
  8. Cool and Slice: Remove the blondies from the oven and allow them to cool in the pan for about 20 minutes. Use the parchment paper overhang to carefully lift the blondies out of the pan, transfer to a cutting board, then slice into squares and serve.

Notes

  • Be careful not to overmix the batter once the flour is added to keep the blondies tender and soft.
  • Using parchment paper makes for easy removal and clean slicing.
  • The cinnamon swirl and optional topping add a delightful texture and flavor contrast.
  • Room temperature eggs ensure a smooth batter consistency.
  • Store blondies in an airtight container at room temperature for up to 3 days or freeze for longer storage.
