Preheat oven to 350°
Line a baking sheet with parchment paper or a silicone baking mat. Set aside.
In bowl of stand mixer cream together butter and brown sugar, approximately 2 minutes until light and fluffy. Add in vanilla diced eggs and continue mixing. (You will still see egg bits in the batter, this is ok)
Add in baking soda, salt and flour and mix until combined.
Stir in chocolate chips.
Scoop onto prepared pan using a cookies scoop or a large spoon.
Bake for 9-10 minutes until edges begin to golden. You don't want to over-bake these, if in doubt under-bake. Because of the lack of wet eggs, the batter will be dry, making cookie dense. Over-baking will produce hard, dry cookies.
Allow to cool for a few minutes on baking sheet before set enough to transfer to a wire rack.
