Here's one I use that everyone loves.
1 package Devil's Food cake mix
1 cup Canna-butter (cold)
1 1/2 cups chopped nuts
1 package choclate chips
1 package toffee chips
1 14 oz can sweetened condensed milk

you chop the cold cannabutter into the cake mix until it's finely chopped. Then spread it into the bottom of a glass baking dish, lightly sprayed with cooking oil. After it's evenly pressed into the bottoem of the pan, spread out the chopped nuts, the choclate chips and the toffee pieces evenly onto the top. Open the sweetened condensed milk, and pour over the top of the nuts and chips. Pop the whole thing into a pre heated oven 325 degrees F. Bake until the sweetened milk bubbles to a light golden colour. Take the pan out and let it cool completely, or wait until it quits bubbling and top with vanilla ice cream.
This goes over pretty well.
