Soften butter in the microwave (cut sticks of butter in 2-3 pieces each and put in a microwave safe bowl and microwave for 30-60 seconds until soft/slightly melted).
In a large bowl add the butter, white sugar, brown sugar, maple syrup, and vanilla and mix together.
Add the eggs and mix.
Add the flour, baking soda and salt and mix really well.
Stir in the chocolate chips.
Refrigerate the dough for atleast 2 hours, I let mine sit overnight.
Take out and roll into balls about 2 tablespoons big (the size of a golf ball).
Preheat the oven to 350 and bake 12 cookies for 16 minutes.
Notes
Note: I used a hand blender to mix the ingredients if you have something like a KitchenAid mixer that would work very good too!
