Preheat the oven to 350°F (175°C).
In a bowl, whisk together the flour, baking soda, and salt. Set aside.
In a separate bowl, cream together softened butter, brown sugar, and granulated sugar until light and fluffy.
Beat in the eggs one at a time, followed by the vanilla extract and cream soda.
Gradually mix in the dry ingredients until just combined, then fold in the butterscotch chips.
Scoop tablespoon-sized portions of dough onto a baking sheet lined with parchment paper.
Bake for 10-12 minutes or until the edges are lightly golden.
Let the cookies cool on the baking sheet for a few minutes before transferring them to a wire rack.
