Lemon Cheesecake Mousse Cups

These chilled mousse cups combine softened cream cheese, whipped cream, fresh lemon, and vanilla. Powdered sugar dissolves smoothly and supports the whipped structure. Portioning the mousse into six dishes before chilling gives the recipe a defined yield and avoids repeated handling.

Recipe details

Yield: 6 servings, about 1/2 cup each
Prep time: 20 minutes
Chill time: 2 hours
Equipment: two mixing bowls, electric hand mixer, microplane, citrus juicer, flexible spatula, measuring cups and spoons, six 6-ounce dessert dishes

Ingredients

8 ounces full-fat cream cheese, softened
1/2 cup powdered sugar
1 tablespoon finely grated lemon zest
3 tablespoons fresh lemon juice
1 teaspoon vanilla extract
1 cup cold heavy whipping cream
Pinch of fine salt
6 thin lemon half-slices, optional garnish

Instructions

Wash and dry the lemon before zesting. Zest only the yellow surface, then juice the fruit and measure 3 tablespoons.
Beat softened cream cheese and powdered sugar on low speed until combined. Increase to medium and beat for 1 minute, scraping the bowl. Beat in lemon zest, juice, vanilla, and salt until smooth.
In a clean, dry bowl, beat the cold cream on medium until it forms firm peaks. Stop when the lifted beaters leave peaks that hold their shape; continued beating can make the cream grainy.
Fold one third of the whipped cream into the cream-cheese mixture to lighten it. Fold in the remainder in two additions, sweeping the spatula under and over rather than stirring vigorously.
Divide among six dishes, using about 1/2 cup per dish. Cover and refrigerate at least 2 hours. Add the optional lemon slices immediately before serving.

Mixing and troubleshooting

Cream cheese must be soft enough to beat without lumps, while the whipping cream must remain cold enough to trap air. These ingredients therefore begin at different temperatures. If the cream-cheese base contains lumps, press it through a fine-mesh sieve before folding in the cream. Do not try to beat lumps out after folding, because that removes the mousse’s volume.

Measure lemon juice rather than adding the juice of an unspecified fruit; lemon size varies and excess liquid can loosen the mousse. Use powdered sugar, not granulated sugar, which may leave a gritty texture. This is a spoonable mousse, not a firm no-bake cheesecake filling.

Serving and variations

Serve cold with fresh blueberries or sliced strawberries. Optional fruit and crumbs are separate from the stated formula. For lime mousse, replace both lemon zest and juice with equal measured amounts of lime. Reduced-fat cream cheese produces a softer result and is not recommended when firm presentation matters.

Storage and safety

Keep covered at 40°F or below and use within 3 days. Do not leave dairy mousse at room temperature longer than 2 hours, or 1 hour above 90°F. Return unused portions to refrigeration promptly. Freezing can make the dairy mixture grainy, so it is not recommended.

For defined portions, set all six dishes on the work surface before dividing the mousse. Add one spoonful to each dish in rotation until the bowl is empty rather than filling one dish completely at a time. A piping bag can produce a decorative top, but it does not change the yield and should be filled only after the mousse is fully mixed.
