Simple Chocolate Mousse

I first started making this Simple Chocolate Mousse when my brother was diagnosed with diabetes. It’s easily adjusted to become a sugar free and low fat dessert, as the only ingredients are Jell-O Pudding (prepared) and Cool Whip. As you can imagine, the flavor combinations are endless, and this simple mousse can be incorporated into so many other desserts like trifles and cakes! It’s now a family staple, diabetes or not!

This is possibly the most valuable dessert in my recipe arsenal.

I use it all. the. time. ALLLLLLLLLL the time. There are so many reasons I love this recipe that it’s kind of hard to organize them into a nice cohesive post, so you’ll have to forgive me if I start senselessly gushing…

If you’re a Sunday dinner guest in my house, there’s a more than decent chance you’ll be served this chocolate mousse for dessert.

Why? Because I’m a horrible grocery shopper. I never make a list, and (therefor) never have the ingredients I need for an actual planned out recipe. But I always have the 3 ingredients this recipe requires on hand.

Because our church ends at 4:30. Which means I usually have less than an hour to prep dinner and dessert (and of course I didn’t start anything before we went to church… that would be too easy). But you’ll never know it took me less than 5 minutes to prepare this mousse.

Because I can dress it up with cookies and cake to make it fancy, like a trifle. Or I can customize each person’s mousse cup with the topping of their choice.

Because I can make this mousse in a million different flavors. So even if I serve it to you on more than one occasion, it’s never the same dessert twice.

And finally, because it won’t make anyone who’s dieting (including myself) feel guilty about eating dessert. Isn’t that the worst??

Fun flavor variations I’ve personally tried and loved:

  • Nutella: 1/4 cup nutella + prepared chocolate pudding
  • Peanut Butter: 1/4 cup peanut butter + prepared vanilla pudding
  • Cookies and Cream: 1 cup crushed Oreos + prepared white chocolate pudding
  • Salted Caramel: substitute 1/4 cup caramel sundae sauce for 1/4 cup milk + 1/2 tbsp sea salt + vanilla pudding
  • Substitute a flavored creamer for half of the milk, like I did here.
  • Cheesecake flavored pudding works well with just about everything!

There are soooooo, so, so, SO many different ways to use this mousse. Just to name a few…

  1. Make a trifle! Layer the mousse with a low fat or sugar free cake and fruit for another diet friendly dessert recipe to keep in your back pocket!
  2. Make a cake! I layered Peanut Butter mousse (instead of frosting) with sugar free chocolate cake for my brother’s birthday.
  3. Make a Poke Cake! This mousse would be divine over ANY poke cake. Like peppermint mousse on this one. Or the salted caramel mousse on this one (it’s pumpkin toffee!).
  4. Use it in fruit salad! The cheesecake, vanilla, and white chocolate flavors are especially yummy with fruit…
  5. Use it as a fruit dip!
  6. Make parfait cups! I do this all the time for dinner guests. I like to layer white chocolate mousse with Oreos and hot fudge sauce or caramel sauce (or both!). Adding layers of any type of cookie crumb is yummy too– they become really soft.
  7. Make a pie! Omit 1/4 cup milk from the recipe, and simply pour the mousse in a graham cracker pie crust and let it chill for a few hours before serving. Voila!
  8. Mix in some leftover rice for instant rice pudding!

…plus SO. MUCH. MORE.

Also… because I know a million of you are going to ask me this: homemade whipped cream is not really an acceptable substitute in this recipe. You can give it a shot, and maybe it’ll hold up if you serve right away. But it won’t hold up in the refrigerator for long.

And while we’re on that note… DO NOT USE STORE BRAND WHIPPED TOPPING! The name brand makes a difference here. Use COOL WHIP for best results. This post isn’t sponsored, it’s just truth.

Ok. Recipe time!

Simple Chocolate Mousse


  • 1.34 oz box of Sugar Free Instant Jell-O pudding mix, chocolate
  • 1 1/4 cup fat free or 1% milk (do not use whole)
  • 8 oz. container of Cool Whip (I always use Lite or Sugar Free)


  1. Whisk together the pudding mix and the milk in a large bowl just until it begins to thicken.
  2. Immediately whisk in half of the cool whip. This needs to be done quickly to avoid lumps, and I suggest only doing half of the cool whip so that it's manageable to mix in quickly.
  3. Fold in the remaining cool whip with a rubber spatula.
  4. Serve immediately or store in the refrigerator covered. Add toppings as desired.
  5. Serves 4-6

  16. I’m so excited to make this for a dinner we’re hosting! Thank you! Is the Cool whip used frozen or thawed by the way?

  17. I hope you tell people it’s sugar-free before you serve this. Some people don’t like to eat poison.

  18. How many days ahead can I make this? And does it freeze well?


    • I’ve never frozen it and then thawed it, but I have eaten it frozen (in cake form)– it was great!

      You can make it a few days ahead of time and just give it a good stir before stirring.

  19. oh my gosh! Does your brother have type 1 diabetes or two? My sis i T1D and it is great to “meet” people who also live with it
