This coffee cake mix by Invisible chef was one of the simplest cake mixes I have ever made. For this Chocolate Truffle mix you will need an egg and a little bit of milk or heavy whipping cream. I made mine with milk and it turned out light and tasty. I initially expected a very sweet chocolaty pastry that would be more along the lines of a cup cake. Although this was not completely the case, it still turned out a great tasting treat. The cake was not as sweet as I expected but I came to find out that traditional coffee cakes usually are not. It still had a deep rich chocolate undertone. I am a huge chocolate fan and this satiated my pallet perfectly in conjunction with a great cup of brew.
