Fraisier cake (with a recipe for homemade marzipan). The use of the marzipan is totally optional, and not necessary. I topped my cake with whipped cream piped rosettes, and a few sliced strawberries,
An incredibly pretty French cake filled with delicious strawberries and crème pâtissière. Tricky to achieve but certain to impress. The crème pâtissière is made into crème mousseline with the addition of butter to the custard.
Preparation time

Serves 8 to 10
Equipment needed: 9 inch springform pan
Makes 1 x 23cm/9in cake
Ingredients
· 125g/4½ ounces caster sugar
· 4 free-range large eggs
· 2 lemons, zest only, finely grated
· 125g/4½ ounces self-raising flour, plus extra for flouring
· 50g/1¾ ounces unsalted butter, melted and cooled slightly, plus extra for greasing
For the crème pâtissière
· 600ml/20 fluid ounces whole milk
· 1 large vanilla pod
· 4 free-range eggs, plus 2 free-range egg yolks
· 180g/6¼ ounces caster sugar
· 1 tbsp kirsch
· 100g/3½ ounces cornflour
· 150g/5½ ounces butter, cut into cubes and kept at room temperature
For the lemon syrup
· 75g/2¾ ounces caster sugar
· 2 lemons, juice only
70 ml water
To finish the cake
· 200g/7oz marzipan
· 200g/7oz dark chocolate, for decoration
· 600g/1lb 5oz medium sized strawberries
Method
1. Preheat the oven to 350°F.
2. Grease and flour a 9 inch springform pan or use baking spray. Make a 9 inch circle of parchment paper to place in the pan and spray it also.
3. Place the sugar, eggs and lemon zest in a large bowl set over a pan of simmering water. Using an electric hand whisk, whisk the mixture over a medium heat until doubled in volume and pale in color. The mixture is at the right stage when it forms a ribbon trail when the whisk is lifted out of the mixture. Remove from the heat. A better alternative method is to use a stand mixer to whisk the sugar, lemon zest and eggs together on the highest speed for 5 minutes. This will get the proper ribbon stage and does not overbeat. If you overbeat, you will not get the volume needed for the genoise sponge.
4. To make the equivalent of UK self raising flour:
Use US All-purpose flour. Add 2 teaspoons of baking powder to each cup of all-purpose flour. UK self-rising flour doesn’t contain salt, so you shouldn’t add it unless the recipe specifically calls for it. You can also add ¼ teaspoon of baking soda if you’re baking with buttermilk, yogurt, or cocoa, as these ingredients need extra leavening. Make sure your baking powder is fresh, as old baking powder can prevent cakes from rising.
5. Sift in two-thirds of the flour and gently fold into the whisked mixture with a metal spoon or spatula. Add the remaining flour and fold again. Try to keep in as much of the air as possible. Make sure all the flour is incorporated into the mixture.
6. Melt the unsalted butter, and let it cool to room temperature while you are whisking the egg mixture. After the flour is folded into the egg mixture, gently fold in the cooled melted butter. If the butter is too hot, it will cause the mixture to deflate. It is the addition of the butter that makes this sponge a genoise.
7. Immediately pour the mixture into the cake tin and bake for 25-30 minutes or until the sides of the cake begin to come away from the tin and it is pale golden-brown. On the masterclass Mary said to use 160 degrees C fan for 35 minutes, but I got good results with conventional oven at 350°F for 35 minutes. The cake will spring back when pushed by a finger.
8. When cooked, allow the sponge to cool a little bit in the tin, then turn out onto a cooling rack. Be careful as this sponge is quite delicate. It should be just under 5cm/2in in height.

9. To make the crème pâtissière, pour the milk into a wide based pan, split the vanilla pod along its length using a sharp knife, and scrape the seeds from the pod. Add the pod and seeds to the milk. Bring the milk up to the boil, then take it off the heat.
10. Whisk together the eggs, sugar, kirsch and cornflour in a medium sized bowl until blended. US equivalent of cornflour is cornstarch. Mix the cornstarch and sugar together with a whisk first to prevent lumps, then add the eggs, egg yolks and liquor. The extra egg yolks help enrich the mixture. Kirsch can be replaced by the liquor of your choice, such as rum, Grand Marnier, Limoncello, etc.
11. Remove the vanilla pod from the milk and pour the hot milk through a sieve into the egg mixture. Whisk to combine. When first pouring the hot milk into the egg mixture, whisk continuously to prevent the eggs from scrambling (thus tempering the eggs), then add the rest of the milk whisking continuously. I did not use a sieve, as I wanted any vanilla seeds to be incorporated. I just removed the pod remnants from the milk prior to the tempering of the eggs and the use of the rest of the milk.
12. Once all the milk is added, pour the custard back into a clean saucepan and set over a medium heat. I used the same saucepan I had used to heat the milk and vanilla. I have a heavy copper saucier pan that is prefect for making crème patisserie, as the slightly sloped sides grants easy access to get the whisk into the sides and bottom of the pan.
13. Stir the custard constantly until the mixture thickens. The mixture will take about four minutes to thicken, but when it does it happens very quickly, so you need to really keep stirring to prevent lumps. Whisk until smooth. Use an infrared thermometer to reach 170-175°F and immediately remove from the heat. Keep whisking to prevent lumps.
14. Cook the mixture until the crème is very thick, so that it can be piped and it will hold its shape. Stir in the room temperature butter until thoroughly melted and combined. If you didn’t add the liquor yet, it can be added at this stage. If the mixture looks a bit curdled after reaching the right temperature, don’t worry. The addition of the butter will smooth it out (the butter temperature matters as if too cold, it will not blend in well, too warm, it will be oily–the butter should be slightly softened at room temperature).
15. Allow to cool slightly, pour into a shallow dish, cover with parchment paper and chill in the fridge for about an hour until really cold and set firm. This chills it faster as it cools over a larger surface area – alternatively you could fill the piping bags with it at this stage and leave overnight to chill.
16. Place the ingredients for the lemon syrup in a small saucepan with 70ml/4½ tbsp water. Heat gently until the sugar dissolves, then boil rapidly for two minutes. Remove from the heat and set aside to cool. I found it is not necessary to add water, just heat the sugar with the lemon juice and stir to dissolve the sugar.
17. Meanwhile, roll out a thin disc of marzipan to fit a 23cm/9in circumference circle. It is best if you draw around the 23cm/9in base of another loose bottomed tin for the perfect circle. For best results and a perfectly flat surface, chill it in the fridge until it is needed.
18. Slice the sponge in half horizontally, creating two slim discs of cake. The cut must be as level as possible as it will be visible in the finished cake.
19. Place a strip of acetate plastic around the inside of the springform tin after buttering the sides of the springform pan. If you don’t have the acetate plastic (available online), line the base and sides with cling film or parchment lined foil.
20. Cut the geniose in half horizontally. Place one half cut side up in the bottom of the cake tin. Then liberally brush the sponge with half the syrup. With the back of a spoon, gently squash the edges of the cake down so that they are pushed directly against the sides of the tin, creating the defined edges necessary for the Fraisier cake.
21. Rinse, dry, and trim off the green tops of about 12 strawberries, then cut them vertically in half. Try and make sure they are all the same height.
22. Place the cut sides of the strawberries against the plastic on the inside of the tin, pressing down into the sponge. The strawberry halves should be sitting snugly beside each other, so it looks like a little crown inside the tin.
23. Take the chilled crème pâtissière out of the fridge and spoon two thirds of the crème into a piping bag, fitted with a 1cm/½in nozzle.
24. Pipe a swirl covering the exposed sponge completely in the bottom of the tin.
25. Then pipe between each of the strawberries so the gaps are filled right to the top with the crème pâtissière.
26. Set about 3-5 strawberries to one side for decoration, then hull and quarter the rest of them and place on top of the crème, so it raises the inside of the cake by about an inch.

27. Pipe another swirl of crème pâtissière on top of the cut strawberries to cover the whole surface. Then smooth with a palette knife.
28. Place the other disc of sponge on top of this, with the cut side uppermost, so it has a completely flat top. Brush with the remaining syrup.
29. Gently press the top down quite firmly, so that the cake and filling push against the acetate to create the distinctive smooth and defined sides of the Fraisier cake.
30. Lay the chilled marzipan circle on top of the cake and put the whole thing back in the fridge to set. Make some pretty decorations of your choice with melted dark chocolate.
31. Instead of marzipan, cover the top of the cake with heavy cream sweetened with sugar and vanilla, or agave syrup and whipped. Use an offset spatula to make a thin layer of the whipped cream, then pipe some rosettes of cream along the cake edge, and in the center. Decorate with strawberry quarters.

32. Refrigerate the cake. When ready to serve, remove the cake from fridge and serve immediately.
34. Very carefully release the spring tin/loose bottom and remove the cake from the tin and from the acetate or cling film.
35. Place onto a serving plate and decorate with reserved strawberries, chocolate decoration and a dusting of icing sugar. Serve chilled.
Homemade Marzipan:
Ingredients
- ¾ cup + 1 tbsp (90 g) blanched almond flour (see notes)
- 9 tbsp (70 g) powdered sugar or powdered Erythritol (see notes)
- 1 ½ tbsp (20 ml) water or a liquid sweetener (see notes)
- 1/4-1/2 tsp almond extract (optional but very recommended)
- ½ tsp rose water food grade (optional)
Instructions
I recommend using a kitchen scale for this recipe.
- First, process the almond flour and powdered sugar in a food processor.
- Add the water (or your favorite liquid sweetener), almond extract, and rose water (optional) and pulse a couple of times until the dough holds together and forms a ball.
- If the dough is too dry and doesn’t hold together, add a tiny bit more water (or syrup). Make sure to add just a little until a thick dough is formed. If it’s too sticky and wet, add more almond flour.
- Take out the marzipan ball and knead it on a clean surface for about 30 seconds. You can now shape it into a log, wrap it up in cling wrap and refrigerate it. It will firm up slightly in the refrigerator.
- If you use agave syrup or corn syrup, you should be able to store it in the fridge for up to 2-3 weeks (probably even longer) or up to 3 months in the freezer. If you use water, use it within 10 days.
Notes
- Almond flour: Instead of almond flour, you can use 90 grams of whole almonds. Cover them with boiling water. Wait until the water is lukewarm, then slip off the skins with your fingers. Drain the almonds really well (pat-dry with a tissue) and process them in your food processor. You will need less water, maybe just 1/2 to 1 tsp. Add more if the mixture is too dry. I recommend using finely ground blanched almond flour for convenience.
