Preheat oven to 375° F.
In a stand mixer beat together the butter and sugars for about 5 minutes.
Add eggs (one at a time) and vanilla and mix until smooth.
In a separate bowl sift together the flour, cinnamon, baking soda, and salt.
Add the dry ingredients to the stand mixer while you prepare your chocolate and blueberries.
Chop your chocolate bar and add to the flour/dough mixture with chocolate chips. Add blueberries.
Mix on low, pulsing the mixer on and off to prevent flour from flying everywhere. Mix until a dough forms with no flour streaks.
Scoop 4-5 large cookies at a time onto a parchment-lined baking sheet with at least an inch of space between each.
Bake for 12-15 minutes until lightly golden brown.
