sea salt (I like flaky Maldon sea salt)for topping
Instructions
Preheat oven to 350°F. Line two baking sheets with parchment paper and set aside.
In a medium bowl, combine flour, baking powder, baking soda and salt and set side.
In a large bowl, using a hand mixer or stand mixer, beat butter and peanut butter until smooth and combined. Add both sugars and beat to combine. Beat in egg and vanilla extract. Add the flour mixture all at once and beat until just combined. Stir in about ⅔ cup of butterscotch chips (reserving the rest for topping the cookies).
Scoop the dough into balls (I use a 1 ½ tablespoon scoop), and place a couple inches apart on the prepared baking sheets. Press a few of remaining butterscotch chips on top of the dough balls. Bake for 8-11 minutes, until the edges are light golden brown, but the center is still slightly underdone. Immediately sprinkle with sea salt, and place the sheets on wire racks to cool. Repeat with remaining dough, allowing the cookie sheets to cool COMPLETELY before placing dough on them.
