Preheat your oven to 350°F (175°C). Line your baking sheets with parchment paper to prevent sticking.

In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until it’s light and fluffy.

Beat in the eggs one at a time, then stir in the vanilla extract until well combined.

In a separate bowl, whisk together the all-purpose flour, baking soda, and salt.

Gradually mix the dry ingredients into the wet mixture until just combined. Be careful not to overmix!

Gently fold in the butterscotch chips and chocolate chips, ensuring they’re evenly distributed throughout the dough.

Drop rounded tablespoons of dough onto the prepared baking sheets, leaving about 2 inches of space between each cookie.

Bake for 10-12 minutes, until the edges are golden and the centers are set.

Allow the cookies to cool on the baking sheet for about 5 minutes before transferring them to a wire rack to cool completely.
