What precisely is mousse? Mousse is a light and fluffy dessert formed by beating air into a soft, creamy base. A traditional mousse is created with eggs and/or cream, and it can be flavored with anything from chocolate to fruits and spices.

While not a typical mousse, this lightly sweetened lemon mousse comes together quickly and does not require cooking. It’s the ideal summer dessert because there’s no need to stand over a hot stove today!

Serve lemon mousse as an after-dinner dessert or at your next BBQ or picnic. It is also suitable for making an icebox cake. Lemon mousse can be made a day ahead of time and refrigerated until ready to serve!

Lemon curd – This can be prepared or purchased from a store. You can find lemon curd near the jams and jellies at your local grocer.
Heavy cream – Heavy cream is a must in this recipe – you’ll be making a homemade whipped cream to fold into the other ingredients. Other dairy products, such as half-and-half and full milk, will not work. Heavy cream contains just enough milkfat to whip into whipped cream and hold its shape.
Confectioner’s sugar – We’re adding a small amount of confectioner’s sugar to our mousse today. It adds just enough sweetness to balance the tart lemon flavor. This dessert is meant to be lightly sweetened. If you prefer a sweet dessert, you are welcome to add more sugar.
Lemon zest – Adds a punch of fresh lemon flavor. Optionally, reserve a little extra to use as a garnish.

If you’ve never made homemade whipped cream before, you may want to check out my detailed post here, for extra pictures and a full list of tips and tricks: Homemade Whipped Cream

Here are my favorite tips for making homemade whipped cream:

Use very cold heavy cream. Cold cream will whip up much more easily than a room temperature or warm cream.
If your home is very warm, and for a higher chance of success when making whipped cream, refrigerate your bowl and whisk (or hand mixer beaters) for 20 minutes before beginning.
Whip your heavy cream on medium speed, not high speed. It’s less messy and there’s less of a chance of overmixing your cream.
Use a large bowl – your cream will double in size and there will be some splashing while you mix your cream.
