ingredients
(Here’s a tip: Check out the full list of ingredients and measurements in the recipe card below.)
4 large eggs (room temperature)
100 g granulated sugar (1/2 cup)
60 g cake flour (1/2 cup)
20 g unsweetened cocoa powder (3 tablespoons)
60 ml milk (1/4 cup)
40 g unsalted butter (3 tablespoons)
1 tablespoon honey
1 teaspoon vanilla extract
1/4 teaspoon salt
directions
I start by preheating my oven to 160°C (320°F) and lining small molds or a baking pan with parchment paper.
I gently melt the butter with the milk, then set it aside to cool slightly.
In a bowl, I whisk the eggs and sugar together over a warm water bath until the mixture becomes pale, thick, and slightly warm. Then I remove it from heat and continue whisking until it reaches a ribbon-like consistency.
I sift the cake flour, cocoa powder, and salt together, then carefully fold them into the egg mixture to keep the batter airy.
I slowly add the milk and butter mixture, along with honey and vanilla extract, folding gently until everything is smooth.
I pour the batter into the prepared molds and lightly tap them to remove air bubbles.
I bake for about 25–30 minutes until the cakes are set and spring back when touched.
Once done, I let them cool slightly before removing them from the molds.
Servings and timing
I usually get about 6 small individual cakes from this recipe.
Preparation time: 15 minutes Cooking time: 25–30 minutes Total time: about 45 minutes
Variations
I sometimes add chocolate chips for extra richness and texture. I like to swap cocoa powder with matcha powder for a different flavor profile. I occasionally drizzle melted chocolate or dust powdered sugar on top for a more decorative finish. I also enjoy adding a hint of orange zest to give the cakes a subtle citrus note.
storage/reheating
I store these cakes in an airtight container at room temperature for up to 2 days. If I want them to last longer, I refrigerate them for up to 5 days.
When I want to enjoy them warm, I reheat them in the microwave for about 10–15 seconds, which brings back their soft texture.
FAQs
How do I keep the cake soft and fluffy?
I make sure not to overmix the batter and fold gently to keep the air inside.
Can I use all-purpose flour instead of cake flour?
I can, but I usually replace it with slightly less all-purpose flour and add a bit of cornstarch for a lighter texture.
Why did my cake turn dense?
I notice this happens if I overmix or deflate the batter while folding.
Can I make this recipe without cocoa powder?
Yes, I can skip the cocoa powder and replace it with more flour for a classic Castella cake.
Can I freeze these cakes?
I can freeze them for up to one month and thaw them at room temperature before serving.
Conclusion
I enjoy making these personal chocolate sponge Castella cakes because they are simple, elegant, and incredibly satisfying. Every time I bake them, I get a soft and airy texture with a rich chocolate flavor that feels special without being complicated. They are perfect for everyday treats or small celebrations.
