- 1 3/4 ounces (50 grams) potato starch
- 4 eggs, egg whites and egg yolks separated
- 1 1/3 ounces (40 grams) cocoa powder
- 1/2 teaspoon baking powder
- 5 cups (1 kilogram) fine sugar, divided
- 2 pounds (1 kilogram) strawberries
- 6 3/4 ounces (200 grams) soft butter
- 6 3/4 ounces (200 grams) mascarpone
- 1 teaspoon vanilla extract
- 1 tablespoon lemon juice

Method
Step 1
Preheat the oven to 350 and line a 7-8 inch springform with parchment paper and grease the sides with butter.
Step 2
In a medium mixing bowl, combine the flour with the potato starch, baking powder and cocoa powder.
Step 3
In a separate medium mixing bowl, beat the egg yolks with 6 tablespoons of sugar with a whisk until it is light and fluffy, 2-3 minutes.
Step 4
In the bowl of a stand mixer fitted with the whisk attachment, beat the egg whites until stiff, then gradually add 5 tablespoons of sugar, whisking constantly, until the mixture is stiff and shiny. Add the egg yolks and gently stir with a spatula. Then sift the dry ingredients and stir gently with a spatula just until combined.
Step 5
Pour the batter and bake until a toothpick inserted into the center comes out dry, about 35-40 minutes. Let cool completely.
Step 6
In the meantime make the mascarpone frosting. Place the 1 3/4 pound of strawberries in a large saucepan and cook for 15 minutes over a low heat. Press through a fine sieve into a bowl and set aside.
Step 7
Place the butter in the mixing bowl and beat for about 10 minutes until light and fluffy. Slowly add 1 3/4 cup of sugar while beating. Finally add the mascarpone, strawberries, zest and lemon juice, beat for 5 minutes more until combined.
Step 8
Cut the remaining strawberries into small cubes. To assemble cut the cake into three layers, place one layer, flat side up, on a plate or cake stand, spread 3 tablespoons of mascarpone frosting and add half of the cut strawberries.
Step 9
Place the second cake layer, spread 3 tablespoons of mascarpone frosting and add the rest of the strawberries. Add the third cake layer and cover the top and sides of the cake with a thin layer mascarpone frosting, decorate with the strawberries and the remaining frosting. Chill 30 minutes or until ready to serve. Enjoy!
