- 2 tablespoons powdered sugar (optional, for extra sweetness)

Instructions
Step 1: Prepare the Ingredients
Wash the lemons thoroughly before zesting. Finely grate the yellow outer peel, avoiding the white pith, which can taste bitter. Squeeze fresh lemon juice and strain out any seeds.
Keep the heavy cream refrigerated until just before whipping, as cold cream whips faster and creates a fluffier mousse.
Step 2: Whip the Cream
Pour the cold heavy whipping cream into a chilled mixing bowl.
Using an electric mixer, beat on medium-high speed for 3–5 minutes until soft peaks begin to form.
If desired, add powdered sugar during the final minute of whipping.
Do not overmix, or the cream may become grainy.
Step 3: Prepare the Lemon Mixture
In a separate bowl, combine:
- Sweetened condensed milk
- Fresh lemon juice
- Lemon zest
- Vanilla extract
Whisk until smooth and fully combined.
The lemon juice will naturally thicken the mixture slightly.
Step 4: Fold Everything Together
Using a rubber spatula, gently fold the whipped cream into the lemon mixture.
Work slowly and carefully, folding rather than stirring.
Continue until the mixture becomes smooth, fluffy, and evenly blended.
Avoid overmixing to preserve the airy texture.
Step 5: Fill the Dessert Glasses
Divide the mousse evenly among six serving glasses or dessert bowls.
Smooth the tops with the back of a spoon if desired.
Cover each serving with plastic wrap.
Step 6: Chill
Refrigerate the mousse for at least 2 hours.
For the best flavor and texture, chill for 4 hours or overnight.
The mousse will become thicker and creamier as it chills.
Step 7: Garnish and Serve
Before serving, decorate with your favorite toppings.
Popular choices include:
- Fresh whipped cream
- Lemon zest
- Thin lemon slices
- Fresh berries
- Mint leaves
- Cookie crumbs
Serve chilled for the freshest taste.
Tips for Perfect Lemon Mousse
- Always use freshly squeezed lemon juice for the brightest flavor.
- Chill the mixing bowl before whipping the cream for better volume.
- Fold gently to maintain a light, airy texture.
- Taste the mixture before chilling and adjust sweetness if desired.
- Refrigerate for several hours to achieve the perfect consistency.
- Garnish just before serving to keep toppings fresh.
