How To Make Toffee Butterscotch Cake

1. Preheat oven to 350F, line a 9×13-inch pan with foil for easier cleanup, and spray with cooking spray; set aside.
2. To a large bowl, add the cake mix, eggs, water, oil, and mix on high-speed with a handheld electric mixer for about 2 minutes. Turn batter out into prepared pan and bake the cake for about 23 to 25 minutes, or a toothpick that’s inserted in the center comes out clean.
3. After taking the cake out of the oven, using the blunt end of a wooden spoon, poke about 75 holes evenly over the surface of the cake, poking nearly to the bottom of the cake; set aside.
4. To a medium bowl, add the butterscotch topping, sweetened condensed milk, whisk to combine, and slowly and evenly pour over the surface of the cake. Run a spatula back and forth as necessary over the surface of the cake to encourage the mixture to sink down into the holes.
5. Cover cake and place it in the fridge for at least 2 hours, or until chilled. For a make-ahead option, note that the cake will keep in the fridge for a couple of days before serving it.
6. Before serving, evenly spread the whipped topping over the cake, evenly sprinkle with the toffee bits, and serve.
