Ingredients
For ingredients and detailed instructions, refer to the recipe card below.
- Butter: I always choose European-style unsalted butter. Bring it to the kitchen counter to soften an hour before you start.
- Sugar: Use granulated sugar or replace it with caster sugar.
- Lemon zest: Opt for organic, untreated lemon and zest it with a Microplane.
- Eggs: Use large eggs at room temperature. Use an egg separator to separate the egg whites from the yolk.
- Flour: The recipe calls for all-purpose flour, the same as plain flour.
- Baking powder: Use fresh aluminum-free baking powder.
- Salt enhances the flavors of the dessert.
- Shredded coconut adds texture and flavor to the cake. If desired, you can replace it with desiccated coconut.
- Milk: I prefer whole milk, but you can also use low-fat milk if desired.
- Vanilla extract: Choose the most flavorful Madagascar Bourbon pure vanilla extract, or replace it with an alcohol-free vanilla flavor.
- Red plums: Use seasonal dark red plums, ripe but not too soft. Replace fresh plums with the best stone fruits, such as apricots, peaches, nectarines, or cherries. However, avoid fresh berries such as strawberries, raspberries, and blackberries since they are too watery for this cake.
- Almonds: Use store-bought toasted flaked or sliced almonds or toast nuts in the oven at 300°F (150°C) for 10 to 15 minutes.
- White wine vinegar and cornflour are used for making stable meringue.
How to make Louise cake step-by-step
Step 1. Preheat the oven to 365°F (185°C). Butter and line the bottom and sides of a round 9-inch (23 cm) springform pan (with a removable base) with parchment paper.
Step 2. In a large bowl, sift flour, baking powder, and salt with a flour sifter and place aside. In a small separate bowl, mix the vanilla extract with milk.
Step 3. To make the biscuit, place softened butter, sugar, and lemon zest in the bowl of a stand mixer fitted with a paddle attachment. Cream butter and sugar at medium-high speed until smooth and homogeneous.
Step 4. Add large egg yolks, one at a time, and mix until combined. Add shredded coconut and mix well. Lower the mixer speed and gradually add the dry ingredients to the principal preparation, alternating with milk and vanilla mixture.
Step 5. Pour the cake batter into the prepared tin and smooth the top with a rubber spoon.
Step 6. Bake the cake for 25 minutes. Check for doneness with a skewer or knife blade: the cake base is ready if the skewer or knife blade inserted into the center comes out clean. Let the biscuit cool in a pan.
Step 7. Wash and dry plums. Divide each plum vertically into halves and discard stones. Slice each half into four parts, eight segments per plum and 40 segments in total.
Step 8. Increase the oven heat to 390°F (200°C).
Step 9. Arrange plum segments on the biscuit base with the cut side down in a circular pattern. Don't overlap the fruit; otherwise, it will make the buttery base of the cake watery.
Step 10. To make the meringue, use a stand mixer with a whisk attachment to beat egg whites and salt at medium-high speed until soft peaks. Gradually add sugar and whisk at high speed until stiff peaks form, and the meringue becomes glossy. Add vanilla extract, vinegar, and cornflour to the meringue mixture and whisk again. Finally, add toasted flaked almonds and gently mix with a silicone spatula.
Step 11. Distribute the meringue on top of the plums. Use a spatula to swirl the meringue to get rough waves, curls, and peaks.
Step 12. Bring the cake to the middle rack of the oven. Immediately lower the oven temperature to 355°F (180°C) and bake for 35 minutes until the meringue turns into a slightly golden brown crust.
Step 13. Remove the cake from the oven and let it cool, still in the cake pan, for at least 30 minutes.
Step 14. Unmold the cake and peel the paper from the sides of the cake. Let the cake cool down completely before serving.
Expert Tips
- For the best results, use a springform cake tin with a removable bottom to facilitate cake removal. Alternatively, use an adjustable cake ring.
- If you use small plums, cherries, or other smaller stone fruit, quarter each fruit.
- Watch out for the color of the meringue crust while baking.
Recipe variations
- Biscuit: To make a chocolate-coconut biscuit, replace 2 ½ tablespoons (20 g) of all-purpose flour with the same amount of cocoa powder.
- Fruits: Use frozen or fresh unpitted fruits. Or choose raspberry jam filling instead of fruits to make the cake all year round.
- Flavorings: Switch flaked almonds with shredded coconut while making the meringue topping.
Storing and freezing
Store the Louise cake in an airtight container in the refrigerator for 3 to 5 days. However, the top of the meringue may start softening after the first day.
Can you freeze Louise cake? You can freeze the Louise cake for up to one month, but the meringue layer on top will lose its texture.

- Increase oven heat to 390°F (200°C). Arrange plum pieces on top of the biscuit, close to each other, and cut side down. Don't overlap the fruit; otherwise, it will make the middle layer of the cake watery.

Liz says
I want to make this cake, but I’m no clear on the directions starting on numeral 7; so the cake has to be cooked completely and then layer plum and bake again at 390 and bake it for a third time with the meringue. Will this make the cake dry?
Irina Totterman says
Hello Liz, you will bake the cake, then layer the plum slices and meringue. Then, bake for the second time. The cake layer itself is dry, but due to the plum juices, it will be soaked a bit. Just make this cake; it is the best! Trust me! Happy baking!!
Mat says
There is a chocolate meringue cake that I make similar to this and it's amazing. Even though it's baked twice, it moist and tasts so good. I look forward to baking this cake in the Australian summer for my family. Love Ottolenghi's recipes, thank you for sharing.
Irina Totterman says
Hello Mat, Thank you for your interest in the recipe and for the chocolate meringue idea. It will perfectly pair with cherries! Happy baking!
