Mix two ingredients together, set aside.

Preheat oven to 350 degrees. Melt butter in microwave in microwave safe dish (30ish seconds) and let cool. Add the eggs and vanilla to a large bowl and beat eggs with hand mixer. Add the brown sugar to the mix. Combine well. Add butter and mix. In separate bowl, mix the remaining ingredients except for the cinnamon sugar. Mix dry ingredients together and add a little at a time to the wet mixture. Once wet and dry mixtures are combined thoroughly. Pour mixture into a greased or lined 13×9 pan.

Take 1 Tablespoon of the cinnamon sugar mixture and create two lines down the length of the blondie dough. Taking a toothpick, make figure eights through the sugar. Bake for 30-25 minutes until a toothpick inserted in the center comes out clean. PLace on wired rack to cool completely.

Place cream cheese in a bowl and using a fork, break up until smooth. Add in the milk and combine, add in the powdered sugar a little at a time until fully incorporated.

Cut the blondies into bars and top with icing, or ice the whole pan then cut into bars, enjoy!
