Ingredients

For the Lemon Base

• 3 large lemons (juice and zest)
• ½ cup granulated sugar
• 3 egg yolks
• 2 tablespoons cornstarch
• 1 cup milk
• 2 tablespoons butter

For the Mouss

• 1 cup heavy whipping cream
• 2 tablespoons powdered sugar
• 1 teaspoon vanilla extract

Optional Garnish

• Lemon slices
• Fresh berries
• Mint leaves
• Extra whipped cream
• Crushed graham crackers

Instructions

Step 1: Prepare the Lemon Mixture

Start by washing the lemons thoroughly. Zest them first, then squeeze out the juice. Fresh lemon juice gives the mousse its bright flavor, so avoid bottled juice if possible.

In a medium saucepan, whisk together the sugar, egg yolks, cornstarch, and milk until smooth. Add the lemon juice and zest.

Place the saucepan over medium heat and cook while stirring constantly. The mixture will slowly begin to thicken after several minutes. Continue stirring to prevent lumps or scorching.

Once thick and creamy, remove the pan from the heat and stir in the butter until fully melted and combined.

Transfer the lemon mixture to a bowl and cover the surface directly with plastic wrap to prevent a skin from forming. Let it cool completely.

Step 2: Whip the Cream

In a chilled mixing bowl, add the heavy whipping cream, powdered sugar, and vanilla extract.

Using a hand mixer or stand mixer, beat until soft peaks form. The cream should look fluffy and smooth but not overly stiff.

Be careful not to overmix, or the cream may become grainy.

Step 3: Fold Everything Together

Once the lemon mixture has cooled, gently fold it into the whipped cream using a spatula.

Use slow folding motions to keep the mousse light and airy. Continue until fully combined and smooth.

The final texture should be silky, fluffy, and pale yellow.

Step 4: Chill the Mousse

Spoon the mousse into serving glasses, ramekins, or small dessert bowls.

Cover and refrigerate for at least 2 hours, though overnight chilling gives the best texture and flavor.

The mousse will become thicker and creamier as it chills.

Serving Suggestions

Lemon mousse is beautiful on its own, but toppings make it even more special.

Try serving it with:

• Fresh strawberries or raspberries
• Blueberries for extra freshness
• Crushed vanilla cookies
• Toasted coconut
• White chocolate shavings
• A dollop of whipped cream

For a fancy presentation, serve the mousse in clear dessert glasses with layers of berries or cookie crumbs.

Tips for the Best Lemon Mousse

Use Fresh Lemons

Fresh lemon juice and zest create the best flavor. The zest contains natural oils that make the mousse extra fragrant.

Chill Before Serving

Cold mousse tastes lighter and creamier. Give it enough time to fully set.

Fold Gently

Overmixing can flatten the whipped cream, making the mousse dense instead of airy.

Make Ahead

This dessert is perfect for preparing in advance. It stays fresh in the refrigerator for up to 3 days.

Variations

Lemon Berry Mousse

Layer the mousse with strawberries or blueberries for a fruity twist.

Lemon Cheesecake Mousse

Fold in softened cream cheese for a richer texture.

Coconut Lemon Mousse

Add a few tablespoons of coconut cream and top with toasted coconut flakes.

Honey Lemon Mousse

Replace part of the sugar with honey for a warmer sweetness.

Storage

Store the mousse covered in the refrigerator for up to 3 days.

Freezing is possible, though the texture becomes slightly firmer. If frozen, let it thaw in the refrigerator before serving.
