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.
  2. Mix the Wet Ingredients: In a large bowl, whisk together the melted butter, brown sugar, and granulated sugar until smooth. Add the eggs and vanilla extract, whisking until fully incorporated. The mixture should be thick and glossy.
  3. Combine the Dry Ingredients: In a separate bowl, sift together the flour, cream of tartar, baking soda, and salt. Gradually add the dry ingredients to the wet ingredients, stirring until just combined. Be careful not to overmix, as this can lead to dense blondies.
  4. Prepare the Cinnamon Swirl: In a small bowl, mix the granulated sugar and cinnamon for the swirl. Stir in the melted butter until the mixture resembles wet sand.
  5. Layer the Batter and Swirl: Spread half of the blondie batter evenly into the prepared baking dish using a spatula. Sprinkle the cinnamon-sugar mixture over the batter, spreading it evenly across the surface. Dollop the remaining batter over the cinnamon-sugar layer and gently spread it to cover. Use a butter knife to create swirls by dragging it through the batter in a zigzag pattern.
  6. Add the Optional Topping: If desired, sprinkle the cinnamon-sugar topping evenly over the surface for an extra spiced crunch.
  7. Bake: Bake the blondies in the preheated oven for 30–35 minutes, or until the edges are golden brown and a toothpick inserted into the center comes out with a few moist crumbs.
  8. Cool and Slice: Allow the blondies to cool in the pan for 20 minutes. Use the parchment paper overhang to lift the blondies out of the pan, then transfer them to a cutting board. Slice into squares and serve.

Notes

  • For best results, use room temperature eggs to ensure the batter mixes smoothly.
  • Do not overmix the batter to avoid dense blondies.
  • You can store leftover blondies in an airtight container at room temperature for up to 3 days.
  • For a gluten-free version, substitute all-purpose flour with a gluten-free flour blend.
  • Ensure to let the blondies cool before slicing to maintain their shape.
