Introduction

Chocolate mousse was my first low-carb dessert love. Back at the start it was just heavy cream and unsweetened cocoa, beaten together, and that was enough to get through a week.

This version adds two things to that: a couple of tablespoons of monk fruit sweetener, and a teaspoon of vanilla. The sweetener is the obvious one. The vanilla is the one that makes the difference — unsweetened cocoa whipped into cream has a flinty edge to it, and the vanilla is what rounds that off.

The Method, In Full

Everything into one bowl, and beat for about three minutes. You are looking for stiff peaks: lift the beaters out and the peak that comes up with them should stand rather than fold over.

Stop there. Cream whipped past that point goes grainy, and then buttery, and there is no beating it back.

Which Is Also Why It Is Easy to Adjust

Nothing here has to set or bake, so the mixture in the bowl is the finished thing — taste it and change it. More cocoa if you want it darker, more sweetener if you want it sweeter.

The two tablespoons in the card are Lakanto monk fruit, the granulated blend that measures like sugar. Stevia packets are the other thing in our cupboard, but they are concentrated — two tablespoons of those is not a version of this recipe, and no converted amount for them is given here. Add a packet, taste, decide. Making it from scratch instead of from a box of instant pudding is mostly about getting to make that call yourself.

Want a chocolate dessert that sets instead? Our keto chocolate pudding is built on cream cheese and firms up in the refrigerator in about an hour.

About these numbers: We are home cooks, not certified nutritionists. Nutrition is shared as a courtesy. We pick a representative product for each ingredient, and our recipe system works out the totals from the amounts in this recipe, so please treat them as a helpful estimate rather than a guarantee. The brands you buy, any swaps you make, and how generously you portion the recipe will all move these numbers.

Directions

  1. Combine all ingredients in a large mixing bowl.

  2. Beat with an electric mixer until stiff peaks form, about three minutes, then serve.

  3. Top with whipped cream and garnish with unsweetened cocoa nibs, if desired.

Notes

  • Serve immediately, or cover and refrigerate until ready to serve.

On Top, and Elsewhere

Whipped cream on top — yes, whipped cream on whipped cream — with unsweetened cocoa nibs or Lily’s chocolate chips for some crunch.

We remade it in mason jars once with ChocZero bark broken over the top, which is the version in the photo below.

It would also work as a cake icing, with the condition that comes with sweetened whipped cream: it wants to be kept cold, so this is for a cake coming out of the refrigerator rather than one standing on a table all afternoon. I am a buttercream person myself; my mom loves a whipped cream icing on a cake.
