How to Make Lime Mousse Cups

Prep mode (keeps screen awake)

Chill the equipment and prep the limes

Place a medium metal or glass mixing bowl and beaters in the fridge for 10 minutes so the cream whips faster.
Zest and juice your limes before you start mixing so you can work quickly once the cream is whipped.
Whip the cream for the mousse

Pour 1 cup cold heavy whipping cream into the chilled bowl and beat on medium speed until soft to medium peaks form.
Stop as soon as the cream holds its shape on the beaters, because overwhipped cream can turn grainy.
Mix the lime cream cheese base

In a separate large bowl, beat the softened cream cheese with an electric mixer until very smooth and fluffy.
Add the sweetened condensed milk, lime juice, lime zest, vanilla, and a pinch of salt, and beat until blended and silky.
Fold in the whipped cream and add color

Gently fold the whipped cream into the lime cream cheese mixture in three additions, using a spatula and light, sweeping motions.
For a festive green color, add a drop or two of green food coloring and fold just until evenly tinted.
Portion and chill the mousse cups

Spoon or pipe the mousse into small cups, jars, or shot glasses, filling each about two thirds full.
Cover the cups and chill in the fridge for at least two hours, so the mousse firms and the flavors meld.
Whip the topping

About 10 minutes before serving, whip ¾ cup cold heavy whipping cream with powdered sugar, vanilla, and a pinch of salt.
Beat until soft to medium peaks form, so the cream pipes or spoons nicely but still tastes light.
Garnish and serve

Top each chilled mousse cup with a generous dollop or swirl of whipped cream right before serving.
Finish with a little fresh lime zest on top for color and bright citrus aroma.

Substitutions

Green food coloring -> matcha powder: Use 1/4 to 1/2 teaspoon finely ground matcha instead of food coloring for a soft natural green shade. It adds a gentle earthy note that plays nicely with the tangy lime.
Heavy whipping cream -> canned coconut cream: Chill a can of full-fat coconut milk overnight and scoop out the thick cream to whip instead of dairy cream. The mousse will taste richer with a light coconut flavor that pairs well with lime.
Cream cheese -> mascarpone: Swap the cream cheese for the same amount of mascarpone for an ultra silky, slightly less tangy mousse. It keeps the rich texture but gives a more dessert-like cheesecake vibe.

Tips

Get the right cream peaks: For the mousse, stop whipping when peaks softly curl; stiffer cream will not fold smoothly and can deflate the mixture.
Soften cream cheese properly: Let cream cheese sit at room temperature for 30 minutes so it beats smooth without tiny lumps.
Use fresh lime for best flavor: Fresh lime juice and zest give that bright, zippy flavor; bottled juice often tastes dull and slightly bitter.
Pipe for a party look: Transfer mousse and whipped cream to piping bags for tidy layers and pretty swirls in clear cups or shot glasses.
Make it ahead safely: You can assemble the mousse cups up to one day ahead; add whipped topping and zest within two hours of serving.

FAQ

How can I fix grainy or curdled mousse?: Grainy mousse usually comes from overwhipped cream or cream cheese that was still too cold. Gently fold in a few tablespoons of unwhipped cream, then chill; this often smooths the texture enough.
My mousse did not set; what went wrong?: If the mousse stayed loose, the cream may not have been whipped enough to hold soft peaks. Next time, beat the cream a bit longer and be sure to chill the cups at least two hours.
Can I make this without an electric mixer?: You can whip the cream and beat the cream cheese by hand with a whisk, though it will take longer. Chill the bowl and whisk, and take breaks so the cream does not warm up as you work.
How long will the mousse cups keep in the fridge?: The mousse cups keep well for about two to three days in the fridge, tightly covered. After that, the texture loosens and the lime flavor starts to fade.
