Recipe FAQs and Expert Tips

How do I cut this cake?

To slice this cake, make nice clean cuts, run a sharp knife under very hot water for a moment, dry and quickly but carefully make a cut for the first slice. Rinse the knife under very hot water, dry it, and repeat cutting as before with every slice.

    Hi! I made this recipe twice already and it came out so delicious, like Olive Garden. So decadent. I did have to cut the cake more than half way to make sure everything fit in my springform. But, we all certainly didn't mind sampling the leftover cake! Love how you added that detail in the directions!

    Iโ€™m wanting to make this for my moms birthday, but all I have is white almond bark - would that work in place for the chocolate chips if I were to cut it up small? Thanks!

      December 31, 2022 at 9:10 am

      You could try it but my worry is this...almond bark is made from vegetable fats opposed to cocoa butter which is used for white chocolate. These differences make them set up different when melted, mixed in with other ingredients and cooled. Cocoa butter when melted, mixed in stuff and cooled has a velvety smooth texture. Almond bark may end up with a heavier texture and possibly grainy depending on the quality. For the drizzle the almond bark would be fine but I would worry about the white chocolate layer in this recipe.

    Hi Mindee -
    You have a comment not to use Hershey cocoa and your ingredient photo shows Ghiardelli, but I can't quite see all the details on the bag.

    I'm trying to ascertain which of the two types of baking cocoa you are using:
    1) Natural (Unsweetened/Pure)
    2) Dutch Processed

    I know there is a huge difference between the two and using the wrong type can ruin a recipe. One way to tell Natural is usually used with baking soda and Dutch Process in recipes with baking powder. However if a recipe calls for both it is hard to tell.

    I can't wait to make this for my husband's birthday (tomorrow - lol) but would hate to ruin it by guessing wrong.

    Thanks so much - I love the detail and photos you have provided in your recipe.

        Great cake recipe. Took a long time but worth it. Only complaint is you shouldn't have a pic of a small pint of heavy cream in the picture. The recipe calls for a total of a quarter of cream. I had to run to the store half way through Baking cause I only bought a pint based on the pic. Learned my lesson to read every measurement before buying ingredients.

    Hi Mindee
    I really want to try this recipe. My problem is I really donโ€™t like cream cheese and was wondering if there is something I could substitute or should I use a chocolate mousse recipe that doesnโ€™t call for it
    Thanks

      You canโ€™t really tell that there is creamed cheese in this dessert - it is more mousy than anything- a truly delicious dessert.
