Add eggs, unsalted butter, and rum extract and stir to combine.
2 large eggs, 3/4 cup butter, 1 tsp rum extract
Fold in the white chocolate and butterscotch chips.
1/2 cup white chocolate chips, 1/2 cup butterscotch chips
Scoop the dough and form into balls. Place the balls on a parchment lined baking sheet and press down slightly.
Bake for 12 to 15 minutes, until the edges are golden brown but the center is still soft. Allow to cool on the baking sheet for 5 minutes, then transfer to a wire cooling rack to cool completely.

Notes
When buying your cake mix, look for the 15.25 ounce size. Betty Crocker has switched to a smaller box (13.25 ounces) so look for Pillsbury or other larger sizes.
You can use instant or regular butterscotch pudding for your cookies.
Store your cookies at room temperature in an airtight container or on a plate covered in plastic wrap.
