Step‑by‑Step Instructions

• Preheat your oven to 350°F (175°C) and grease or line a 9×13-inch baking dish with parchment paper.
• In a large mixing bowl, combine 1 cup of melted butter with 1 ½ cups of brown sugar. Stir in two large eggs and 2 teaspoons of vanilla extract until smooth.
• Gently fold in 2 cups of all-purpose flour and ½ teaspoon of salt, being careful not to overmix.
• In a separate bowl, mix together ½ cup of brown sugar, 1 tablespoon of cinnamon, and ¼ cup of melted butter until you achieve a sandy texture.
• Spread the blondie batter evenly in the prepared baking dish. Drop dollops of the cinnamon mixture on top and swirl gently with a knife.
• Bake in the preheated oven for 25–30 minutes until edges are golden and a toothpick comes out mostly clean.
• Allow to cool in the pan before preparing the cream cheese icing.
• In a mixing bowl, beat 4 oz of cream cheese until smooth. Gradually add 1 cup of powdered sugar and 1–2 tablespoons of milk, mixing until creamy.
• Stir in ½ teaspoon of vanilla extract, then drizzle over the cooled blondies and cut into bars.
