How to Make 3-Ingredient Lemon Mousse
Ingredients:
- 1 cup heavy cream (the full-fat kind, we’re not here to play)
- 1 (14 ounce) can sweetened condensed milk
- ½ cup lemon juice (freshly squeezed, please – you’re worth it!)
Step-by-step instructions:
Whip the Cream: In a large bowl, whip the heavy cream until stiff peaks form. Don’t over-whip, or you’ll end up with butter. Unless you want lemon butter, which, honestly, doesn’t sound half bad.

Combine the Ingredients: Gently fold in the sweetened condensed milk and lemon juice. Fold, don’t stir! We want to keep that lovely airiness. Imagine you’re gently tucking in a tiny cloud.

Chill: Pour the mousse into individual serving glasses or a larger bowl. Cover and refrigerate for at least 2 hours, or until set. Patience is a virtue, especially when it leads to deliciousness.

Common Mistakes to Avoid
- Over-whipping the cream: Remember, stiff peaks, not butter! Keep a close eye on it.
- Using bottled lemon juice: Fresh is always better, trust me. Bottled juice can sometimes have a weird aftertaste.
- Not chilling it long enough: This mousse needs time to set. Don’t rush it! Otherwise it’ll be a sad, soupy mess.
Variations & Customizations
- Keto-Friendly: Swap the sweetened condensed milk for a sugar-free version and use a sugar substitute to sweeten.
- Spicy Version: Add a pinch of cayenne pepper or a few drops of hot sauce for a surprising kick.
- Berry Bliss: Layer fresh berries between the mousse for a fruity twist.
Recommended Equipment

FAQ Section
Can I use low-fat cream?
You can, but it won’t whip as well. The full-fat cream is what gives it that lovely, airy texture.
Can I use lime juice instead?
Absolutely! Lime mousse is equally delicious. Just swap out the lemon juice for lime juice.
How long does it last in the fridge?
It should last for about 3-4 days, if you can resist eating it all in one sitting.
