Instructions

1. For the blondies: Preheat the oven to 350° F. Spray a 9-inch by 13-inch pan with cooking spray.
2. In a large, microwave safe bowl, melt the butter, one stick at a time for about 30 seconds or until completely melted.
3. In a large mixing bowl, combined the melted butter and brown sugar and beat until well mixed.
4. Next, add the eggs, one at a time and mixing each one completely. Then add the vanilla and beat it into the batter.
5. In a separate bowl, combine the remaining dry ingredients: flour, cinnamon, baking soda and salt and gently whisk to combine. Slowly add the dry ingredients to the batter and mix until combined and a thick batter has formed.
6. Spread the blondie batter in the prepared baking pan, spreading evenly.
7. Bake at 350° F for 18-22 minutes. The dough will rise in the middle and be slightly crispy on the edges. To test for doneness, stick a toothpick into the center of the bars. If the toothpick comes out clean, the blondies should be done. Remove from the oven and cool completely.
8. For the frosting: In your mixing bowl, combined the softened butter and cream cheese and beat until well combined.
9. Next add the powdered sugar and the vanilla extract and continuing beating until smooth. Add the heavy cream as needed to create a smooth and creamy texture. Spread evenly over the cooled bars and sprinkle with cinnamon as desired.
10. I suggest these bars to be refrigerated once they are frosted and allow them to come to room temperature for 20-30 minutes before serving.
