1-Start by preheating your oven to 350°F and lining a baking sheet with parchment paper for easy cleanup. In a medium bowl, whisk together the flour, baking soda, baking powder, salt, and cinnamon to blend these dry ingredients smoothly. This step sets the base for your butterscotch chocolate chip cookies and ensures even baking.

2-Next, in a large bowl, cream the melted butter and sugars until they become light and thick; this takes about 3 minutes and helps create that soft texture. Mix in the vanilla extract and egg until everything is smooth and well combined. Now, add the dry ingredients to the wet mixture and stir gently until just blended, avoiding overmixing.

3-Fold in the chocolate chips, butterscotch chips, and nuts if you’re using them, to distribute the flavors evenly. Scoop the dough using 2 tablespoons per cookie onto the prepared baking sheet, spacing them apart for proper spreading. Bake for 10-12 minutes until the edges turn golden and theRob centers look slightly pale, then sprinkle with flaky sea salt and cool for 10 minutes before serving.
