Instructions

• Preheat your oven to 350°F (175°C) to ensure it reaches the right temperature for even baking.
• Grease a 9×13 inch (23×33 cm) baking pan or line it with parchment paper to prevent sticking and make removal easier.
• In a bowl, whisk together the all-purpose flour, baking powder, ground cinnamon, and salt until well combined.
• In a separate large bowl, combine the melted butter, brown sugar, and granulated sugar, mixing until smooth. Add the eggs one at a time, beating well after each addition, then stir in the vanilla extract.
• Gently fold the dry ingredients into the wet ingredients just until combined, being careful not to overmix to maintain a tender texture.
• In a small bowl, mix together the granulated sugar and ground cinnamon for the topping.
• Pour the batter evenly into the prepared pan. Sprinkle the cinnamon sugar mixture evenly over the top. Bake in the preheated oven for 25-30 minutes or until a toothpick inserted near the center comes out with a few moist crumbs.
• Allow the blondies to cool in the pan for 10-15 minutes. Then transfer them to a wire rack to cool completely before cutting into 16 squares to serve.
