How to Make the 15-Minute Famous Cake
Step 1: Make the Pastry Cream
In a saucepan, whisk together 1 egg, 50g sugar, 10g vanilla sugar, and 15g cornstarch until smooth.
Gradually pour in 250ml milk, whisking constantly.
Cook over medium heat, stirring constantly until the mixture thickens into a smooth pastry cream.
Remove from heat and let it cool slightly.
Step 2: Prepare the Cake Batter
In a large bowl, beat 2 eggs, 100g sugar, and a pinch of salt until light and frothy.
Add 100ml milk and 50ml vegetable oil, and mix until combined.
Sift in 170g flour and 1 teaspoon baking powder, stirring gently to form a smooth batter.
Fold in 50g chopped almonds.
Step 3: Bake the Cake
Preheat oven to 350°F (175°C).
Grease a baking dish or line it with parchment paper.
Pour half of the cake batter into the dish and spread evenly.
Spoon the cooled pastry cream over the batter, spreading gently to cover.
Pour the remaining cake batter over the pastry cream layer.
Sprinkle 50g almond flakes evenly on top.
Step 4: Bake and Finish
Bake for 25–30 minutes, or until the top is golden and a toothpick inserted into the cake layer comes out clean.
Let the cake cool slightly, then dust generously with powdered sugar before serving.
Serving Suggestions
- Serve warm for a cozy treat, or chilled for a firmer texture.
- Pairs perfectly with coffee, tea, or a glass of cold milk.
- Add fresh berries or a drizzle of honey for extra flair.
Variations
For a chocolate twist, add 2 tablespoons of cocoa powder to the cake batter and layer with chocolate pastry cream. You can also swap the almonds for hazelnuts or walnuts for a different nutty flavor.
If you prefer a fruity version, spread a thin layer of jam or fresh berries between the cake and pastry cream layers.
For a lighter option, use almond milk instead of regular milk and replace the sugar with a natural sweetener like honey or maple syrup.
You can also make it gluten-free by substituting the all-purpose flour with a gluten-free blend. To enhance the flavor, add a teaspoon of cinnamon or cardamom to the batter for a warm, spiced note.
If you’re short on time, skip the homemade pastry cream and use store-bought custard or pudding mix.
For a richer texture, fold whipped cream into the pastry cream before layering. If almonds aren’t your favorite, top the cake with shredded coconut or a sprinkle of cinnamon sugar for a delicious alternative.
Tips
To ensure the pastry cream is smooth and lump-free, whisk constantly while cooking and remove it from the heat as soon as it thickens. If the cream becomes too thick, thin it with a splash of milk.
For an extra-fluffy cake, beat the eggs and sugar until pale and doubled in volume before adding the other wet ingredients.
For even baking, use a light-colored metal pan and avoid overmixing the batter once the flour is added. If the almonds on top start browning too quickly, cover the cake loosely with aluminum foil during the last 10 minutes of baking. Let the cake cool for at least 15 minutes before slicing to allow the layers to set.
If you don’t have vanilla sugar, substitute it with 1 teaspoon of vanilla extract added to the pastry cream.
For a more intense almond flavor, add ½ teaspoon of almond extract to the cake batter. To save time, prepare the pastry cream ahead of time and store it in the fridge until ready to use.
How to Store
Store leftover cake in an airtight container at room temperature for up to 2 days. If the weather is warm or humid, refrigerate it to keep the pastry cream fresh.
To prevent the cake from drying out, place a piece of parchment paper over the cut edges before sealing the container.
For longer storage, wrap individual slices in plastic wrap and freeze for up to 1 month. Thaw the cake in the fridge overnight or at room temperature for a few hours before serving.
Note that the almond topping may lose some crunch after freezing, so refresh it with a quick toast in the oven if desired.
To maintain the cake’s texture, avoid storing it in direct sunlight or near heat sources. If the powdered sugar dissolves, dust the cake with a fresh layer just before serving. For best results, enjoy the cake within 24 hours of baking when the layers are at their peak freshness.
