Does that loooooong title get your attention?

I love cheesecake.

And I love chocolate mousse.

Combining the two? Genius.

I’ve only been to Ruth’s Chris Steak House one time but it was memorable and delicious.

But this recipe? Heavenly and one you’ll want to repeat over and over again.

I still have the newspaper clipping I cut out many years ago.

Remember what a newspaper is? Those oversized sheets of paper with newsprint on them?

Yep, I’m telling my age. I still love my newspaper even though it’s shrunk to approximately the size of a napkin.

When I want a dessert to feed my ever growing family (married children and now grandkids, woohoo!), I reach for this amazingly delicious chocolate dessert.

I mean, who doesn’t love oreos with their cheesecake?

The main adjustment I made from my original recipe is to use less filling in order to get it into a 9×13 dish. Even with lessening this amount you still get a recipe that feeds a crowd.

    1. Hi, Janis. I’m glad you liked the recipe and I hope you’ll make it and let me know how it turned out. It’s one of my favorites and makes me hungry just thinking about it! And yes, the dessert outrank everything else on the blog!

  1. You make the best sounding desserts. This reminds me of something my mom used to make. I can’t wait to share in on FB so that she’ll see your recipe. Maybe she’ll make it for me the next time I visit!

  2. Thank you so much for sharing the chocolate cheesecake recipe! It is my very favorite & they don’t have it on the menu anymore. I’ve been looking for this recipe for years!

    1. Hi, Melani! I’m so glad you liked the recipe. I’ve had it for years and years! It makes me hungry just thinking about it! Thanks for visiting Marty’s Musings!

  3. Hi- can you make this 1-2 days in advance? Also do you let the whipped topping thaw before blending it it?
    Thanks in advance

    1. I think this would be fine, Anita, made the day ahead of time and probably even 2 days especially if you’re going to serve it at one time. We eat on it until it’s gone (which usually isn’t very long!) I hope you enjoy it!

    I made this dessert for a friend and her family for thanksgiving and they ranted and raved over it! Thank you for sharing! I can’t wait to make for my own family for Christmas this year. I also made my own whipped topping instead of buying cool whip and I don’t regret it!

    1. This was one of my favorites to make when all my kids were home but we’re empty nesters now so I don’t make it very often! So glad you enjoyed it!
