Step 1: Prepare the Cake - Preheat your oven according to the instructions on the chocolate cake mix box. Grease your 9x13 inch baking pan with cooking spray or butter. In a large mixing bowl, combine the chocolate cake mix with the required ingredients (usually water, eggs, and oil). Mix until smooth.
Step 2: Bake the Cake - Pour the cake batter into the prepared pan and bake according to the package instructions, usually around 30-35 minutes or until a toothpick inserted in the center comes out clean.
Step 3: Poke the Holes - Once the cake is baked, remove it from the oven and let it cool for about 10 minutes. Using a skewer or fork, poke holes all over the top of the cake.
Step 4: Add the Sweetened Condensed Milk - Pour the sweetened condensed milk evenly over the top of the warm cake, ensuring it seeps into the holes you just created. Allow the cake to cool completely.
Step 5: Drizzle the Butterscotch Topping - After the cake has cooled, drizzle the butterscotch or caramel ice cream topping over the top.
Step 6: Top with Cool Whip - Spread the thawed Cool Whip evenly over the top of the cake.
Step 7: Add Toffee Bits - Sprinkle the toffee bits evenly over the Cool Whip layer.
Step 8: Chill and Serve - Cover the cake and refrigerate it for at least 2 hours before serving.
