Assemble the Heart Cake
Slice: Using a long serrated knife, carefully cut the cake horizontally (lengthwise) into two even layers.
Fill: Place bottom layer on serving plate. Pipe or spread a thin frosting border around the edge.
Spread raspberry jam evenly inside.
Top: Place top layer gently over filling.

Notes
Chill the cake 20 minutes before slicing for cleaner layers. The coffee deepens the chocolate flavor without tasting like coffee. Oil + butter keeps the crumb fluffy yet rich.
