1-Preheat your oven: Okay, let’s get hands-on baking these cinnamon blondies is a breeze and super rewarding! Start by preheating your oven to 350°F (175°C) and lining a baking pan with parchment paper for easy cleanup. This step sets the stage for that gooey texture we’re all after, making it perfect for busy parents or students who need quick wins in the kitchen.

2-Mix wet ingredients: In a large bowl, whisk together the melted and slightly cooled unsalted butter with the packed light brown sugar until it’s nice and smooth. Then, add in the large egg, large egg yolk, and 1 tablespoon vanilla extract, mixing everything well to create a rich base.

3-Combine dry ingredients and fold: In another bowl, combine the all-purpose flour, baking powder, and salt, then gently fold this dry mix into your wet ingredients until just combined don’t overmix, or you’ll end up with a gummy result!

4-Add cinnamon sugar and bake: Pour the batter into your prepared pan, and spoon the cinnamon sugar mixture (that’s the 1 tablespoon ground cinnamon mixed with 1/4 cup white granulated sugar) over it in big dollops. Use a butter knife to swirl it through, creating that marbled magic everyone loves. Pop it in the oven and bake for 30 to 40 minutes; keep an eye on it from the 30-minute mark since ovens vary, and you want the edges golden and the center just set for that perfect chew.

5-Prepare icing and finish: While the blondies cool, whip up the icing: In a small saucepan over medium-low heat, whisk together 1 tablespoon cream cheese, 1 tablespoon heavy cream, 3/4 cup powdered sugar, 1 teaspoon vanilla extract, and a pinch of salt until smooth and melted. Let it cool a bit, then drizzle it over the cooled blondies. Cut into squares and serve these are best enjoyed fresh, with that creamy topping sealing the deal on flavor.
