1 Chocolate Cake Mix (plus ingredients to make the cake)
1 jar Caramel ice cream topping
1 can sweetened condensed milk
1 bag Heath Toffee Bits
1 carton Cool Whip
Make cake per box instructions. When cake is done, take out of oven and poke holes with back of wooden spoon. Pour sweetened condensed milk evenly over the cake. Let is settle. Then, pour caramel topping over the cake (I heated mine up to make it easier). Sprinkle a little of the Heath bits over the cake, if desired (I desired). Put cake in fridge for 1-2 hours. When ready to serve, spread Cool Whip over the cake and sprinkle with Heath Toffee Bits.
This cake is better if it sits overnight.
