We are in the midst of flavorful Strawberry Season. It’s a perfect time to go strawberry picking and make some delicious strawberry desserts.

I teamed up with my friend Amber of SweetAmbs in a Strawberry Collaboration. I made luscious Strawberry Mousse Icebox Cake and Amber made lovely Strawberry Lace Cookies. Check out Amber’s beautifully decorated Strawberry Lace Cookies adorned with SweetAmbs’ signature style.

This delectable layered strawberry mousse icebox cake is amazing. Fruit dessert are one of my favorites. Strawberry mousse is layered with ladyfinger cookies and garnished with fresh strawberries and chocolate leaves. It’s a dessert worthy of any celebration!


Ingredients for strawberry mousse.

To make fruit mousse I use fruit puree mixed with dissolved gelatin carefully blended with soft peak whipped cream and meringue into a velvety smooth strawberry scrumptiousness.


Straining cooked strawberries through a mesh sieve.
  • Let’s start with the strawberry puree. Fruit purees are really easy to prepare and can be made ahead of time. I often freeze them, too.
  • Cook strawberries with a little bit of water, until mushy.
  • Then using a food chopper or an immersion blender break up soft strawberries into a puree.
  • Strain it through a fine mesh sieve. Discard seeds.
  • Refrigerate or freeze for up to 4 months.


Bloomed gelatin in a small glass dish.
  • To make mousse hold its shape I use gelatin to stabilize it.
  • Whisk gelatin with cold water and let it bloom for 5 minutes. Mixture will be spongy, it will spring back when you touch it.
  • Then microwave it on high for 8 seconds, stir well, until completely dissolved.


Soft peak meringue in a bowl.

What is Swiss Meringue?

Swiss meringue is made from egg whites and sugar. I also added 1tsp of lemon juice as I didn’t have any cream of tartar. It works just as well for the meringue.

  • Heat egg whites (3/90grams), granulated sugar (1cup) and lemon juice (1tsp) over a pot of simmering water.
  • Whisking constantly.
  • Heat will gradually dissolve all of the sugar.
  • Mixture will turn into white soapy consistency.
  • Once the sugar is dissolved, attach a candy thermometer onto the heat proof bowl.
  • Bring the mixture 170F, whisking constantly.
  • Remove from the heat and beat with a wire beater. Start on a medium speed and gradually increase it to high. Beat until soft peaks are formed.
  • Set the meringue aside.

How can I tell if it’s a soft peak?

When you pull the meringue up it will form a peak that bends immediately.


Soft peak whipped cream in a bowl.
  • Beat whipping cream with wire beaters, add powdered sugar and vanilla extract.
  • Beat till soft peaks are formed.


Folding strawberry puree, meringue and whipped cream.
  • Whisk dissolved and lukewarm gelatin with lukewarm temperature fruit puree.
  • If you are working with a previously frozen fruit puree be sure to let it thaw ahead of time. If it still appears too cold microwave it on high for 30 seconds until at room temperature or slightly lukewarm is fine, too.
  • Then gradually into the fruit puree fold in meringue and whipped cream until well blended together.
  • Spoon strawberry mousse into a large piping bag.


Layering mousse and ladyfingers into a loaf pan.
  • Line a loaf pan with food plastic wrap, leaving the sides overhang.
  • Layer strawberry mousse and ladyfinger cookies into the pan.
  • Start and with finish with a mousse layer.
  • Cover with a food wrap and refrigerate overnight.


Unmolding mousse cake from a loaf pan.
  • Carefully remove the top food wrap.
  • With a decorating spatula smooth out any creases.
  • Spread a thin layer of melted dark chocolate onto the mousse.
  • Let the chocolate set for 5 minutes.
  • Then flip the whole loaf pan with the layered dessert onto a serving dish.
  • Slowly remove the loaf pan.
  • Peel off the food wrap.
  • Smooth out the creases on the sides and the top as needed.
  • Refrigerate until ready to decorate.


Ghirardelli Chocolate Disks.
  • These DIY chocolate leaves are easier to make than you’d think.
  • I used Ghirardelli Dark Melting disks. They stay melted for a long time and work great. Or you can also use tempered chocolate.
  • You’ll also need parchment squares and a small decorating comb. Or use a fork if you don’t have a decorating comb.
Making chocolate leaves.
  • Pour melted chocolate into a piping bag.
  • Pipe a thick line of chocolate on a diagonal onto a parchment square.
  • Starting in the middle of the piped chocolate line comb the chocolate outwards with the decorating comb. Think of it as if you were making the wings.
  • Then repeat the combing on the other side.
  • Using a plastic cake smoother scrape the chocolate on the sides “drawing” the leaf shape.
  • Let the chocolate harden.


Chocolate leaves dusted with pearl luster dust.
  • Further I decided to brush set chocolate leaves with dry pearl luster dust.
  • At this point you can carefully peel off the parchment.


Chocolate leaves.

If you plan on making chocolate leaves ahead of time I’d recommend to store them attached to parchment squares. There is a lesser chance of chocolate leaves breaking when stored like this. Store them in an airtight container in a cool place.


Piping whipped cream swirls on a strawberry mousse cake.
  • Decorate the top with pretty whipped cream swirls.
  • If making Strawberry Mousse Icebox Cake ahead of time I’d suggest that you stabilize whipped cream topping with gelatin. Otherwise whipped cream may start weeping.
  • Stabilized whipped cream will be fine for up to 3 days.

What can be prepared ahead of time?

Chocolate Leaves and fruit puree, both can be made days ahead. Store them in the fridge, in an airtight container.

Can I use different fruit?

Certainly. If using rhubarb or other fruit on a tarter side, be sure add some sugar to the puree as it may be too tart on it’s own.

I don’t have ladyfingers, can I use something else?

Definitely. Use tea biscuits, graham crackers, Nilla wafers, or cut up cake is fine too.

Do I have to let it rest overnight?

Yes. As a matter of fact, letting it rest 24 hours makes it even better.
