I rarely bake as I am not good at it and my attempts usually flop. However, this cake turned out wonderfully! Very rich but not too sweet, and the coffee really adds a nice touch. And when you get one of those chocolate chips - yum! I was wondering if you think Kahlua could be substituted for some of the hot coffee. Thanks so much! Hungry Alice

I was looking for a mocha cake for my mom's birthday, and when I saw that Kitten had one, I knew it would be a winner. Kitten, you are absolutely my hero. This cake was so easy to prepare, and was just delicious. I had six guests, and all the women wanted the recipe because their men were so impressed. This was just the best. Thanks so much for posting!

This review is for the cake only, not the frosting. I probably shouldn't review this recipe at all because I made so many changes, but since I'm giving it 5 stars, hope it's okay. The changes were made simply because I had to work with what was on hand. I was out of chocolate chips and vanilla so those weren't used. There was only about 2/3 cup of cocoa and 1/2 cup of low-fat mayonnaise, so that's what I used. I added 1/2 cup of 2% plain yogurt to compensate for the missing mayonnaise and also added a spoonful of vinegar. I used cold coffee because the batter had to sit awhile waiting for its turn at the oven and I know from previous experience that adding hot liquids too soon can spoil a cake recipe. After baking I topped the cake with a broiled walnut topping. This made a delicious, rich, moist cake that was enjoyed by all. Thanks for the recipe.
