                Lay parchment into an eight-inch square pan and give it a quick spritz with spray oil. Set it aside for now.

                Toss the butter, marshmallow stuff, condensed milk, sugar, and caramel syrup into a medium pan. Put it over medium-high and stir non-stop until it bubbles up.

                Keep mixing for four more minutes once it's bubbling. It'll look more golden and start to get thicker.

                Stir in all those butterscotch chips. Keep going until you've got a smooth mix with no lumps.

                Take off the heat and whisk for another minute or two—it'll thicken up a bit more. Pour it into your pan and slide it right into the freezer so it sets quickly.

                In a clean pan, put your sugar, butter, marshmallow crème, and condensed milk. Warm over medium heat. Don't stop stirring till it boils.
              
              
              
                07 - 
                Let it boil, turn the heat to medium, and stir for another two minutes. Then take it off the heat.

                Pour in the white chocolate chips and stir gently, just until they're melted. If you stir too much, the chocolate might get weird.

                Right away, dump the white chocolate layer on top of your frozen butterscotch. Use a spatula to softly spread it out to the edges.

                Pop the whole thing in the fridge for a couple of hours or leave it in the freezer for about an hour to finish setting. Cut into little 1-inch bites and dig in.
