Crafting these remarkable Salted Brown Sugar Butterscotch Ice Cream Sandwiches is straightforward when you follow these simple steps:

1. Preheat your oven to 350°F (175°C). Line two baking sheets with parchment paper.
2. In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until light and fluffy.
3. Beat in the eggs one at a time, then stir in the vanilla extract until well mixed.
4. In a separate bowl, whisk together the flour, baking soda, and salt.
5. Gradually include the dry ingredients into the wet mixture, stirring until just combined.
6. Fold in the butterscotch chips evenly throughout the mixture.
7. Using a cookie scoop or tablespoon, drop generous dollops of dough onto the prepared baking sheets, spacing them about 2 inches apart.
8. Bake in the preheated oven for 15-20 minutes, or until the edges are golden brown.
9. Remove from the oven and allow the cookies to cool on the baking sheets for 10 minutes before transferring them to wire racks to cool completely.
10. Once cooled, place a scoop of butterscotch ice cream between two cookies to create a sandwich. Press gently to secure.
11. Sprinkle a pinch of flaky sea salt on the ice cream before placing the top cookie on.
12. Repeat the process with the remaining cookies and ice cream.

These steps ensure you’ll have a delicious batch of ice cream sandwiches that are both satisfying and delightfully indulgent!
