Prepare cake per package instructions and bake in rectangular cake pan.
Cut the cake in half.
Use your hands to crumble the half of cake and put it in the bottom of your trifle bowl
Add 2 Tablespoons of Kahlua Liqueur, shaking it evenly over the entire layer of cake.
Add one of your packages of pudding that you had made previously and spread evenly.
Take a little over half of one container of CoolWhip and spread it on top of the pudding.
Put about a 1/2 a cup of Scor or Heath toffee bits (you can add more if you want, just make sure you have a nice even layer).
You have completed your first half, now you need to repeat all of the steps again
