lemon bar raspberry mousse cakeMaking this lemon bar raspberry mousse cake was so much fun, now that my baby boy is not a baby anymore he wants to know and observe everything I do in the kitchen. I can understand the little guy, I love food as well.

Yesterday Sebastian started pre-school and we had this lemon bar raspberry mousse cake to celebrate such a big milestone. I had so many mixed feelings, almost like a rollercoaster, it went like this: “OMG OMG pre-schools starts, I am so proud of my boy” , followed by doubt “will he be ok? we speak to him only Romanian, he doesn’t know ONE word in english!” and tears start rolling “this is my baby’s first step to independence, he is starting to learn the world on his own, next on the agenda he will come home with a girlfriend and soon its his wedding!”

lemon bar raspberry mousse cakeI honestly don’t know many stress coping techniques, so I did the one that works best for me, make cake, eat your feelings and call it a day! Don’t blame me!

lemon bar raspberry mousse cakeSebastian even helped with the cake, he licked the spatula when I was done, which technically means that he test tasted the mousse. I assume it passed the test as he kept saying “MORE, MORE, MOREEEE”. I used an eggless mousse in this lemon bar raspberry mousse cake, so you don’t have to worry about anything, just eat as much as you can 🙂

My only recommendation for this lemon bar raspberry mousse cake is that you better double the lemon layer, I tried to have a nice balance between flavors, but if you love lemon you can make that layer so much thicker, it will be delicious.

lemon bar raspberry mousse cakeI am telling you this lemon bar raspberry mousse cake is pure bliss, the combo is amazing and all the flavors and textures work so nicely together. The shortbread layer is so buttery and just a little crumbly, the lemon and raspberry flavor work so nicely together and are not too sweet, the mint sugar is optional, but I love mint so much and I think it adds such a nice touch in this cake, by completely taking the flavors into a different direction.

Recipe type: Dessert
Cuisine: American
Serves: 10 slices
Ingredients
  • Shortbread Crust:
  • 2 cups all purpose flour
  • ½ cup confectioners sugar
  • 2 sticks cold butter
  • ½ teaspoon sea salt
  • nonstick baking spray, for greasing the pan
  • Lemon Filling:
  • 1¼ cups granulated sugar
  • ¼ cup all purpose flour
  • 4 eggs
  • lemon zest from one lemon
  • ⅔ cup freshly squeezed lemon juice, I used 4 Meyer lemons
  • Raspberry Mousse:
  • 3 tablespoons fresh lemon juice
  • 2¼ teaspoons powdered gelatin
  • 2 cups fresh raspberries
  • ½ cup plus 3 tablespoons sugar
  • 2 cups cold heavy cream
  • Mint Sugar:
  • ¼ cup fresh mint leaves
  • 1 tablespoon sugar
Instructions
  1. Shortbread Crust:
  2. Preheat oven to 350.
  3. In a large bowl combine the confectioners sugar, flour and sea salt. Cut the cold butter into cubes and add it to the flour mixture. Using your fingers work the mixture until it resembles cornmeal and the butter is completely combined with the flour. Press into a greased springform cake pan and bake for 20 minutes, or until golden.
  4. Lemon Filling:
  5. In the bowl of an electric mixer fitted with the wire attachment add sugar, flour and the eggs one at a time. Whisk on low speed until just combined. Add the zest and the lemon juice, mix until everything is combined.
  6. Pour the lemon filling over the hot crust and return to oven. Bake for another 20-25 minutes. The lemon filling must be settled and it shouldn't jiggle.
  7. When done, remove from oven and cool completely at room temperature IN THE PAN (do not remove the lemon bars from the pan) before topping with the mousse.
  8. Raspberry Mousse:
  9. In a small bowl, place lemon juice and sprinkle with gelatin, let sit until gelatin softens about 2 - 3 minutes. Using a food processor or blender, puree the raspberries until smooth. Pour the raspberry puree through a fine-mesh sieve, pressing on solids and discarding the solids. You should have approximately 1 cup of raspberry puree.
  10. In a small sauce pan, over medium heat add the raspberry puree and ½ cup of sugar, stir and cook just until you see bubbles forming at the edge.
  11. Add gelatin mixture to the raspberry sauce and continue cooking, stirring constantly until the gelatin dissolves, about 1 - 2 minutes. Whisk if needed, to ensure gelatin dissolved. Remove the mixture from heat and let cool to room temperature, about 30-40 minutes.
  12. Add cream and remaining 2 tablespoons of sugar to the bowl of an electric mixer fitted with the wire attachment, beat on medium-high speed until firm peaks form, about 3 minutes.
  13. Using a rubber spatula, gently fold in the raspberry puree mixture and gently stir until all combined. Pour over the lemon bar cake, smooth the top and refrigerate for at least 3-4 hours (better overnight) before serving.
  14. Mint Sugar:
  15. Combine mint leaves and sugar in a food processor and pulse until the leaves are finely chopped. Sprinkle over the cake.
  16. Serving:
  17. Before removing the cake from the pan, run a sharp knife thru cold water and run it over the edges of the cake.
