The Torta Mimosa is more than just a cake; it's a culinary hug, a burst of sunshine, and a beloved Italian tradition, especially celebrated on International Women's Day (Festa della Donna) on March 8th. Its distinctive appearance, resembling the fluffy yellow mimosa flowers that bloom in early spring, makes it a symbol of warmth and joy. This exquisite dessert brings together classic Italian flavours and textures in a truly elegant presentation that never fails to impress.

Our Torta Mimosa recipe promises a light-as-air Pan di Spagna sponge, generously soaked in a delicate lemon syrup, embracing a rich yet ethereal vanilla pastry cream. The addition of finely diced fresh pineapple provides a burst of refreshing tanginess, perfectly balancing the sweetness. The magic truly happens with the final decoration, where delicate sponge crumbs are artfully applied, transforming the cake into a vibrant, edible bouquet of mimosa.

The Secret to a Perfect Pan di Spagna

Creating a truly light and airy Pan di Spagna, the traditional Italian sponge, hinges entirely on the eggs. The key is to whip whole eggs with sugar until they are incredibly pale, thick, and have tripled in volume. This lengthy whipping process incorporates a vast amount of air, which is the sole leavening agent for this classic cake, giving it its characteristic delicate crumb.

Once the eggs are perfectly aerated, the challenge is to gently fold in the dry ingredients – typically plain flour and sometimes cornflour – without deflating the precious air you've worked so hard to build. Use a large spatula and a light hand, folding from the bottom up, ensuring no pockets of flour remain. This gentle technique guarantees a tender, springy sponge that is ideal for soaking up syrup and holding its shape.

Crafting the Silky Crema Pasticcera

The heart of any good Torta Mimosa is its Crema Pasticcera, or Italian pastry cream, which must be lusciously rich yet incredibly smooth and not too heavy. Achieving this perfect consistency requires careful cooking and constant whisking to prevent lumps and ensure the egg yolks and starches thicken the milk to a stable, creamy texture. The balance of sugar and vanilla is crucial here, providing a sweet, aromatic base that complements the light sponge beautifully.

After cooking, it's vital to cool the pastry cream correctly. Transfer it to a shallow dish, cover the surface directly with cling film to prevent a skin from forming, and chill it thoroughly in the refrigerator. This not only ensures food safety but also allows the cream to firm up, making it easier to handle and preventing it from weeping when layered into the cake. A well-chilled cream will hold its shape perfectly within the sponge.

Nonna's tip

For perfectly even sponge layers, use a serrated knife to level the tops before slicing. This ensures a stable and beautiful cake structure.

Ingredients
  • 6 large eggs, at room temperature
  • 180g (3/4 cup + 2 tbsp) caster sugar
  • 150g (1 1/4 cups) plain flour, sifted
  • 30g (1/4 cup) cornflour, sifted
  • 1 tsp vanilla extract
  • 150ml (2/3 cup) water
  • 50g (1/4 cup) caster sugar
  • 1 strip lemon zest
  • 500ml (2 cups) whole milk
  • 4 large egg yolks
  • 120g (1/2 cup + 2 tbsp) caster sugar
  • 40g (1/3 cup) plain flour, sifted
  • 20g (2 tbsp) cornflour, sifted
  • 1 vanilla pod, split and scraped (or 1 tsp vanilla extract)
  • 200g (1 cup) tinned pineapple chunks, drained and finely diced
  • Icing sugar, for dusting
Method
  1. Preheat oven to 170°C (150°C fan/Gas Mark 3). Grease and flour an 20cm (8-inch) round springform tin. In a large bowl, whisk eggs and sugar with an electric mixer on high speed for 10-15 minutes until very pale, thick, and tripled in volume. Gently fold in the sifted plain flour and cornflour in two additions, followed by the vanilla extract, being careful not to deflate the mixture. Pour into the prepared tin and bake for 30-35 minutes, or until a skewer inserted into the centre comes out clean. Let cool in the tin for 10 minutes, then invert onto a wire rack to cool completely.

  2. In a small saucepan, combine water, sugar, and lemon zest. Bring to a simmer over medium heat, stirring until the sugar dissolves. Remove from heat and let cool completely, then remove the lemon zest.

  3. Heat the milk and vanilla pod (if using vanilla extract, add at the end) in a saucepan over medium heat until just simmering. In a separate bowl, whisk egg yolks and sugar until pale and creamy. Whisk in the sifted plain flour and cornflour until smooth. Gradually pour the hot milk into the egg mixture, whisking constantly. Return the mixture to the saucepan and cook over medium-low heat, whisking continuously, until it thickens to a rich cream. If using vanilla extract, stir it in now. Remove from heat, transfer to a shallow dish, cover the surface directly with cling film, and chill completely in the refrigerator for at least 1 hour.

  4. Once the Pan di Spagna is completely cool, use a serrated knife to level the top if necessary. Slice off the top 1 cm (1/2 inch) layer of sponge, set it aside, and then carefully cut the remaining sponge horizontally into two equal layers. Take the reserved top layer and finely crumble it using your hands or a food processor; these crumbs will be used for decoration.

  5. Place one sponge layer onto your serving plate or cake stand. Brush generously with the cooled lemon syrup. Spread half of the chilled pastry cream evenly over the sponge, then sprinkle half of the finely diced pineapple over the cream. Place the second sponge layer on top, brush with syrup, and spread the remaining pastry cream and pineapple.

  6. Using a small amount of the remaining pastry cream (if any) or simply pressing gently, shape the cake into a slight dome. Generously cover the entire cake (top and sides) with the reserved sponge crumbs, gently pressing them on to adhere, ensuring it resembles fluffy mimosa flowers. Dust lightly with icing sugar. Chill the Torta Mimosa in the refrigerator for at least 2 hours before serving to allow the flavours to meld and the cake to set.

Good to know

Frequently asked

Why did my sponge cake turn out dense?

Overmixing the flour deflates the aerated egg mixture; fold the dry ingredients gently and quickly to retain the air that gives the sponge its lightness.

My pastry cream has lumps. What went wrong?

Lumps usually occur from not whisking continuously while heating or not sifting the flour and cornflour. Ensure you whisk vigorously, especially when adding hot milk to the yolks and when cooking.

Can I make this cake ahead of time?

Yes, the assembled Torta Mimosa can be made a day in advance and chilled. This allows the flavours to meld beautifully and the cake to set, making it even more delicious.
