Tips
Use parchment paper between cake and cardboard to prevent sticking and allow easy frosting removal.
Ensure all frosting ingredients are at proper temperature: butter at room temperature, chocolate and cocoa mixture cooled.
Spread raspberry filling carefully to avoid breaking the delicate cake layer.
Good to Know
Cover and refrigerate up to 3 days. Frosting may need room temperature softening before serving.
Cake layers can be baked one day ahead and wrapped. Frosting can be made several hours ahead and refrigerated; bring to room temperature and rebeat briefly before frosting assembled cake.
Slice with a warm, wet knife for clean cuts. Serve at room temperature or chilled.
Common Mistakes
Do not overmix the cake batter after adding eggs to avoid dense, tough cake.
Do not apply frosting to warm cake layers to prevent melting.
Do not skip cooling cocoa mixture before adding to frosting to avoid breaking emulsion.
Do not forget 1-inch border when spreading raspberry filling to prevent squishing out between layers.
