  • In a stand mixer with a paddle attachment, mix together all ingredients until smooth and creamy.  
  • Refrigerate for 1-2 hours and serve. 


  • Mascarpone cheese is sweet, soft cheese. If you can't find it, use ricotta cheese.
  • If you don't like the flavor of lemon, you can also make this mousse in chocolate. See the recipe HERE!
  • You can vary the flavors for this mousse, by using orange extract and orange zest for example. Almond mousse with just the extract will also be fabulous.
  • This is a very rich concoction. Start with 1/4 cup at most per person as it can be very filling.
  • This mousse will last several days in the refrigerator.
  • You can also freeze this in small truffle molds. When it's frozen, pop them out of the molds and store them in the freezer. It's great for portion control!
