Heat your oven to 325°F (165°C/145°C Fan). Line an 8-inch square baking pan with parchment paper for easy removal later.
02 -
In a large bowl, whisk the melted butter with both sugars until smooth and well combined. Add eggs and vanilla, mixing until the batter looks glossy.
03 -
Sift in the flour, cornstarch, baking powder, salt, and cinnamon. Fold everything together with a spatula until just combined - don't overmix!
04 -
Gently fold in the cream cheese chips (or white chocolate chips if using) until evenly distributed throughout the batter.
05 -
Mix the brown sugar and cinnamon in a small bowl. Pour batter into the prepared pan, then sprinkle the cinnamon sugar mixture generously over the top.
06 -
Take a knife and lightly swirl the cinnamon sugar into the batter. This spreads that wonderful cinnamon flavor throughout the blondies.
07 -
Bake in the preheated oven for 40-50 minutes. You'll know they're done when a toothpick inserted in the center comes out mostly clean with just a few moist crumbs.
08 -
Let the blondies cool completely in the pan for about 2 hours. This waiting time is crucial for them to set properly and achieve that perfect chewy texture.
09 -
Mix powdered sugar, cream cheese, and vanilla in a small bowl until smooth. The consistency should be thick but pourable - like honey.
10 -
Drizzle or pipe the cream cheese glaze over the cooled blondies. Cut into 16 squares and enjoy your cinnamon roll inspired treats!
