Strawberry Cake, aka Fraisier

When I was a kid, I’d ask for a “Fraisier” (Strawberry Cake) for every birthday. It was one of my favorite cakes, along with the Chocolate Royal and the Raspberry Tart. My mom would always go to the same little bakery to order it. I was almost more interested in the cake than in the presents. I would just dive into it and get at least 2 big servings. The Strawberry Cake is made of a sponge cake, mousseline cream (pastry cream with butter), fresh strawberries and almond paste. The one I got as a kid was usually a big rectangle. I lightened up a bit the recipe by using a diplomat cream (pastry cream + whipped cream), and I skipped the almond paste (even if it was my fav as a kid) to make it more modern and decorate it with cream and fresh strawberries.

The Strawberry Cake is one of those cake that seems hard to make but are actually quite easy.

Steps to make the Strawberry Cake

You will need to make a sponge cake, a mousseline cream and a sirop.

If you want to have it ready for lunch, you can prepare the sponge cake, the cream and the sirop the day before.

For the cream, we will prepare the pastry cream, add the gelatin and refrigerate. On D-Day, we will add the whipped cream and assemble the cake.

Wrap your sponge cake to make sure it doesn’t dry out. You can keep it room temperature, no need to refrigerate.

The syrop and the pastry cream needs to be refrigerated.

On D-Day, whipped your cream, whisk the pastry cream and combine them. That is your Diplomat cream. Assemble the cake and refrigerate for at least 1 hour to make sure the cream sets. Start early enough to make sure your cake is ready by the time you want to eat it.

This is especially true if you have to travel with the cake. Once I made it last minute and it did not like the 30 minutes’ drive in the summer heat and started being a bit runny. The taste was there, but it wasn’t looking as good as it should have.

The Sponge Cake

It is one of the basics in French Pastry.

Use warm temperature egg white. Do not overmix them with sugar, the texture should not be too stiff. When you lift the whisk out of the bowl, the egg whites should for a peak and shouldn’t drool. Don’t go beyond this point, or the whites will become dry and lumpy.

Use a bit of your preparation to stick your parchment paper to your baking sheet. You can also lightly grease the baking sheet with an oil in spray. This will avoid having the parchment paper move if you have a ventilated (fan) oven.

Diplomat cream

The Diplomate Cream consists of a pastry cream to which we add gelatin and whipped cream. It is also a French pastry basic.

Make sure to soften the gelatine sheets in cold water before making the pastry cream.

To avoid having a dry skin forming on top of the pastry cream, put plastic wrap directly on top of it.

Strawberry syrop

It gives a fruity note to the cake and ensure the cake stays moist. You also don’t want the cake to absorb the cream, adding syrop on the cake will help with that,

We  brush the sirop over the cake before the assembly. To make strawberry puree, simply blend fresh strawberries.
