Instructions:

1. Make the sponge cake:
- Preheat oven to 350°F (175°C).
- Line a 9-inch round cake pan with parchment paper.
- Beat egg yolks with half the sugar until pale and thick.
- In a separate bowl, beat egg whites with salt until soft peaks form, gradually adding remaining sugar until stiff peaks.
- Sift flour and cocoa powder together.
- Gently fold flour mixture into yolks, then carefully fold in egg whites until just combined.
- Pour batter into prepared pan and bake for 15–20 minutes or until a toothpick comes out clean.
- Let cool completely.
2. Prepare the chocolate cream filling:
- Heat heavy cream until just boiling, pour over chopped chocolate, and stir until smooth. Let cool slightly.
- Beat softened butter with powdered sugar and vanilla extract until creamy.
- Gradually add cooled chocolate mixture to butter and beat until smooth and fluffy. Refrigerate if needed to thicken.
3. Make the chocolate glaze:
- Heat heavy cream until warm, pour over chopped chocolate and butter, stir until smooth and glossy.
4. Assemble the cake:
- Slice the cooled sponge cake horizontally into two layers.
- Spread chocolate cream evenly over the bottom layer, then place the top layer on.
- Pour glaze over the cake, smoothing the surface.
5. Chill:
