Follow these simple steps to create your delicious Cinnamon Roll Blondies:

1. Preheat the Oven: Start by preheating your oven to 350°F (175°C). Grease a 9×13-inch baking pan or line it with parchment paper for easy removal.
2. Mix the Wet Ingredients: In a large bowl, combine the melted butter, brown sugar, and granulated sugar. Whisk until smooth.
3. Add Eggs and Vanilla: Next, add the eggs and vanilla extract to the butter-sugar mixture. Whisk until everything is well incorporated.
4. Combine Dry Ingredients: In a separate bowl, whisk together the flour, baking powder, baking soda, salt, and ground cinnamon until evenly mixed.
5. Incorporate Dry into Wet: Gradually add the dry ingredients to the wet mixture, stirring until just combined. Be careful not to over-mix.
6. Prepare the Cinnamon Swirl: In a small bowl, combine 2 tablespoons of cinnamon and ¼ cup of brown sugar. Sprinkle this mixture evenly over the blondie batter in the pan. Use a knife to swirl it into the batter gently.
7. Spread the Batter: Use a spatula to spread the remaining batter evenly over the swirled layer, covering it completely.
8. Bake: Place the baking pan in the oven and bake for 25-30 minutes or until a toothpick inserted in the center comes out clean.
9. Cool: Once baked, remove the pan from the oven and allow it to cool for about 10 minutes.
10. Make the Glaze (Optional): While the blondies are cooling, prepare the glaze by whisking together the powdered sugar, softened cream cheese, and milk until smooth and creamy.
11. Glaze the Blondies: Once cooled slightly, drizzle the glaze over the warm blondies for an added touch of sweetness.

These simple steps will lead you to an incredible batch of Cinnamon Roll Blondies that everyone will love!
