This viral One Ingredient Chocolate Mousse 🍫 recipe is viral for a reason! I don’t know who came up with the brilliant idea of blending chocolate chips with water and refrigerating the mixture overnight to make mousse, but whoever it was, I wish them nothing but green lights and smooth traffic for the rest of their lives 🫡.

Seriously though, it doesn’t get any simpler than this! If you love creamy and light desserts like me but aren’t much of a baker, this is going to be your holy grail. Just 5 minutes of prep time, and you’ll have the most decadent, silky-smooth chocolate mousse that’s low in calories but still satisfies your sweet tooth 🦷.

Why You’ll Love One Ingredient Chocolate Mousse

The chocolate chips give the mousse a deep, rich chocolate flavor 🍫 while the blending process and overnight refrigeration result in a velvety smooth texture that’s both light and airy, yet firm but soft. Despite not being made with traditional mousse ingredients like eggs and cream, this melt-in-your-mouth 🤤 chocolate mousse will taste and feel like you’ve spent hours in the kitchen preparing it.

The best part is, it’s only made with two simple ingredients, so it’s naturally gluten and dairy-free 🙌.

How to Prepare One Ingredient Chocolate Mousse

💦 Blend 1/2 cup of chocolate chips in a blender with 2/3 cup of water for 2 minutes.

🥣 Then pour the mixture into ramekins.

🧊 Refrigerate One Ingredient Chocolate Mousse overnight or until set.

Nonna’s Tip 🍫

Be sure that you blend the chocolate chips and water mixture thoroughly until smooth. This step is important to achieve a silky and creamy texture in the mousse.

Common Questions

How do I ensure the chocolate pudding sets properly?

Make sure to refrigerate the mousse for the recommended time, preferably overnight, to allow it to set completely. If your mousse isn’t set after one night, it may need more time in the refrigerator.

Can I use milk instead of water for a creamier texture?

Yes, you can try using milk (dairy or non-dairy) instead of water for a creamier mousse. Remember, if you are changing or adding ingredients, you may have to experiment and adjust the quantities. If you don’t mind dairy, feel free to also try my Healthy Chocolate Mousse recipe!

How long can I store One Ingredient chocolate Mousse in the refrigerator?

The pudding can be stored in the refrigerator for up to 3-4 days, but make sure to cover the ramekins with plastic wrap or lids to prevent it from absorbing other odors.

What if I want a sweeter chocolate Mousse?

You can certainly try adding a sweetener like honey or stevia to the mousse (I have not tried) when you blend it or use semi-sweet chocolate chips.

      1. Yes. Here’s a simple test of logic as to wether or not something is an ingredient. If you leave it out, will you still end up making the same dish?

        For example if one were to not use water, and instead only chocolate chips, you wouldn’t get mousse, you’d just get tiny pieces of chocolate chips, maybe partially melted depending on the strength of your blender.

        Therefore, water is the second ingredient in this recipe. Just call it two ingredient mousse, that’s still impressive.

    1. Hi Sue, that’s right, you do not need to melt the chips. You just need to blend them thoroughly until the water and chocolate make a smooth mixture.

  1. At top is 1 cup chocolate. 2 cups water.
    Later, I saw 1/3 cups to 2/3 cup.

    Is it really a simple double the water? Mine is not thickening. I used some Almond milk along with the water (2 cups total) so just wonderinf if that’s why may need adjusting.

    1. Hi Charlene, thanks for your note! That was an error which I’ve now corrected. The correct proportions are 1/2 cup chocolate chips to 2/3 cup water. Hope you love it!

      1. 5 stars
        Excited to try this but just need a little clarification. As I read through the post, it says to put 1 cup of chocolate chips and 2 cups of water in a blender. But, down in the actual recipe, if you’re doubling the recipe and using 1 cup of chips, it only calls for 1 1/3 cups of water.

        Should I go with the printed recipe amounts or the amounts listed in the blog post?

        Thanks for your help!

        1. Thank you for the note, Gwen! That was an error which I’ve now fixed. The quantities in the original recipe card are correct: 1/2 cup chocolate chips and 2/3 cup water. Hope you love it!

      1. I mean yea water is something that goes into recipes it’s not like it’s air so it’s an ingredient, I think it would be best to call it a two ingredient recipe

    1. Hi Jaime, the chocolate syrup won’t work. You can certainly try Reese’s cups, though I’m not sure if the peanut butter will effect the outcome.
