Lemon mousse is so refreshing and always a great dessert! We made it extra special by serving it on ice cream cones and covering it with a delicious Italian meringue.

Lemon mousse is light and creamy and can be whipped up in a few minutes. There are so many different recipes for lemon mousse out there, but one of our favorites is this one with only 2-ingredients. It is full of taste, simple, and requires zero cooking skills. We also love that you can make it a day in advance, saving on prep time.
Meringues are so delicious, but a lot of people think they are hard to make. We must admit that we thought so until we started making this Italian meringue recipe. There is no secret! Italian meringue is made with a hot sugar syrup that is mixed into whipped egg whites. The hot sugar syrup partially cooks the egg whites making them safe to eat and gives the meringue a firm texture and flavor.
For a beautiful display, we served the lemon mousse in ice cream cones. The waffle cones are a perfect addition to a dessert table. They not only are cute but give a nice crunch texture to the lemon mousse.

To make this easy lemon mousse, you only need two ingredients: condensed milk and lemon juice! Combine these two ingredients, and you will be amazed by the taste and the texture. As soon as the acid from the lemon juice hits the condensed milk, the mixture thickens. After both ingredients are well-combined, bring the lemon mousse to the fridge for 2-hours to set.

Lemon mousse is ready; now it’s time to prepare the Italian meringue. In a small saucepan, combine sugar and water. Heat over high heat and let it cook until the sugar syrup reaches a temperature of 240F (I use a thermometer to check the temperature). Meanwhile, using a mixer on medium speed, mix the egg whites until soft peaks form, about 2 minutes. With the mixer running, carefully and slowly drizzle in the hot sugar syrup. Increase speed to high and whip until you get a stable glossy meringue. Allow it to cool completely before using it. You can cover it with clingfilm and leave it in the fridge for up to two days.
When it is time to serve, add the lemon mousse to the ice cream cones up to the top, cover it with the Italian meringue. We don’t recommend adding the lemon mousse to the waffle cones too early in advance. If you leave the lemon mousse too long in contact with the cone, the chances are that the cone will get soggy (I did that once, and it did not taste good).
For a toasty golden brown color, we toasted the meringue with a culinary torch. If you don’t have a torch, don’t worry! You can certainly skip this step!!
