Add cream cheese, butter & sugars to a standing mixer. Stir until combined, then whip on high for 1-2 minutes until lighter in color.
Add eggs & vanilla, stir until just combined. Be sure to not over mix.
In a separate bowl, stir together salt, cinnamon, tartar, soda & flour
Start your standing mixer on low, slowly pour in the dry ingredients into the sugar mixture
Stop mixing as soon as the dough comes together. Be sure not to over mix
Press half the cookie dough into a greased, parchment paper-lined 9x13 pan.
Bake for 9 minutes.
While the first half of the bars are baking, make the white chocolate ganache.
In a microwave-safe bowl, add the chocolate chips and cream. Microwave for 30 seconds, then stir. Repeat until the chocolate is fully melted. This took me 1.5 minutes.
When the first half of the cookies are done baking, remove and drizzle the white chocolate ganache all over the top.
Take the remaining dough and flatten small amounts in your hand. Place a bit of flattened cookie dough all over the top of the white chocolate bars until you have used all of the dough and the bars are covered.
Sprinkle as much cinnamon and sugar mix on top of the uncooked bars as you desire.
