Super yummy - thick brownie like consistency. I used a French Vanilla cake mix(the one with pudding in the mix) and a 7-up. Correct in saying that it is not low calorie, but much lower in fat and cholesteral than adding 3 eggs and 1/4 cup of oil to the mix. i can't wait to try root beer with a spice or carrot cake!! - you could do a poke cake with this(poke holes in top of warm cake and pour over cream, sweetened milk, juice or jello mixed with 1/3 c water!) I may try that too.... And I am gonna make a couple of them with Monster's for my halloween party!
