Preheat oven to 350ºF. While preheating, be sure to read tips & tricks in post above for recipe success.
Warm the ½ cup unsalted butter, i.e. [adjustable]1[/adjustable] stick in a microwave-safe bowl or saucepan until it’s just melted.
In a large mixing bowl, combine the butter with the ½ cup light brown sugar and ½ cup granulated sugar. Stir until combined. (I recommend mixing this by hand rather than a mixer.)
Stir in the 1 large egg and 2 teaspoons vanilla extract, followed by the ½ teaspoon baking powder and ½ teaspoon salt.
Mix in 1 tablespoon cornstarch and 1 ¼ cup all-purpose flour, followed by the 1 cup Butterscotch Chips. Mix the dough until well-combined.
Generously grease a cookie cake pan. If you plan to invert the cake onto a tray (rather than serving in the pan), I highly recommend lining the bottom with parchment paper in order for the cookie cake to invert out of the pan easily.
Spread dough into an even layer in pan. Sprinkle on some extra butterscotch chips for added presentation. Bake for 16 to 18 minutes, or until edges are slightly golden brown. Do not overbake; it might look a little under-baked, but the residual heat from the pan will continue to bake the cookie even after you take it out of the oven.
Cool completely and top with buttercream frosting, if desired (this cookie cake is so yummy even without the frosting!).
After allowing the butterscotch cookie cake to fully cool, decorate by piping a border with your large star tip around the cookie cake. Then, drizzle some of the caramel sauce on top of the frosting.
To Make Frosting:
Beat the softened ¼ cup unsalted butter, 1 teaspoon vanilla extract, and ¼ teaspoon salt on medium-high speed for 1 minute until smooth. Turn the mixer to low speed then add the 1 ¼ cups powdered sugar, 1/4 cup at a time. You may need to stop and scrape down sides. One tablespoon at a time, add in the 2 tablespoons Caramel Sauce. Beat on high for 2-3 minutes until creamy and the frosting is at a good consistency to pipe.
If it looks too runny, add more powdered sugar. If it looks too stiff, you can add a tiny bit of milk until you get to the desired consistency.
This will make just enough frosting to pipe a generous border along the edges, as well as write a message in the middle.
