Steps
- Cake: In bowl, cream butter with sugar until fluffy. Beat in eggs, one at a time, then vanilla. Beat in sour cream. Combine flour, baking soda and chocolate; add in 3 additions to creamed mixture alternately with 2 additions of bananas, mixing just until flour is incorporated. Spoon into 2 greased 8-1/2-inch (2.25 L) springform pans, smoothing tops.
- Bake in 350°F (180°C) oven for 35 to 40 minutes or until tops spring back when touched. Let cool on rack for 20 minutes. Remove sides of pans; let cool completely.
- White Chocolate Icing: In saucepan, bring half of the cream to boil; pour over chocolate in bowl, whisking until melted. Add vanilla. Refrigerate until chilled, about 1 hour, whisking often.
- On medium speed, beat chocolate mixture just until ridges hold shape. Beat remaining cream just until soft peaks form; gently fold into chocolate mixture. With serrated knife, slice cakes in half horizontally. Place a top layer, cut side up, on plate.
- Spread top with 3/4 cup (175 mL) icing; cover with single layer of bananas, leaving 1/2-inch (1 cm) border. Cover with 1 bottom cake layer, cut side down; repeat with icing and bananas.
- Repeat with remaining top layer, cut side up, and some of the icing and bananas. Top with remaining cake layer, cut side down.
- Using palette knife, cover cake smoothly with remaining icing. Refrigerate until firm, about 1-1/2 hours.
- Dark Chocolate Ganache: Meanwhile, bring cream to boil; pour over chocolate in small bowl, whisking until melted. Let cool for 20 minutes or until room temperature and still pourable.
- Pour over centre of cake, spreading to edge with clean palette knife, if necessary, and letting some flow down sides.
- Refrigerate until firm, about 40 minutes, or for up to 1 day. To serve, drizzle melted chocolate with fork over remaining bananas; let set. Arrange on cake. Slice with serrated knife.
