How to make Lemon Mousse

I was always one of those people who thought mousse was difficult to make, but once I tried it, I realized I was never more wrong.

  • Crust You can crush Graham crackers into crumbs or purchase pre-made Graham cracker crumbs. combine with the melted butter. and then divide into a glass cup or mason jar to chill in the refrigerator.
  • Whipped Cream Whipping cream or heavy cream should be thickened before adding 1/4 cup powdered sugar. Continue to beat until it reaches a peak, then set it aside.
  • Filling beat the cream cheese until smoother, and then add the remaining powdered sugar, lemon, and vanilla. Fold gently into the whipped cream, being careful not to deflate it.
  • Assemble a spoon or use a piping bag and place the filling over the graham cracker crust.
  • Chill Allow chilling for several hours or overnight.

Tips for Success

Here are a few tips for the best lemon cheesecake mousse.

  • For the freshest and brightest flavor, it’s important to use fresh lemon juice and not the stuff that comes in a bottle.
  • Make sure the cream cheese is at room temperature. This will ensure a nice, creamy texture without lumps, and it won’t whip up properly.
  • When combining the whipped cream and cream cheese, make sure to fold it instead of stirring it; this will help to keep the air in the mousse.
  • For the best results chill overnight or for at least 4 hours.

Frequently Asked Questions

Can I make this mousse ahead of time?

Yes, you make the mousse the day before you plan to serve it. Just prepare it and then cover each cup and store it in the fridge. Just before you are ready to serve it, garnish it with fresh fruit or however you would like it.

How long does lemon cheesecake mousse last?

The mousse will be good in the fridge for up to 3–4 days before it begins to separate.

What is the difference between mousse and pudding?

The difference between a mousse and a pudding is really just the texture. Mousse tends to be a lot lighter and airier than pudding, which is much thicker and heavier, but both are absolutely delicious. With mousse, you can top it with fresh fruit, whereas pudding tends to be a dessert you eat alone because it is heavier.
