How to Make It
Preheat the oven to 350°. Butter a 9-by-13-inch baking dish. Put the bananas on a rimmed baking sheet and bake for about 45 minutes, until dark and soft. Let the bananas cool, then open the peel and scoop the roasted banana pulp into a large bowl.
Meanwhile, in a medium bowl, whisk together the all-purpose flour, baking powder, cinnamon, ground cloves, freshly grated nutmeg and salt.
Using a handheld electric mixer, beat the roasted bananas with the sugar until a puree forms. Then beat in the eggs. In a small bowl, stir together the buttermilk and baking soda, then add to the banana mixture. At low speed, gradually beat in the flour mixture. Gently beat in the melted butter, heavy cream and finely grated orange zest. Fold in the macadamia nuts. Spread the batter in the prepared dish and bake for about 1 hour, until a cake tester inserted in the center of the cake comes out clean. Let the cake cool to warm.
In a small bowl, whisk the yogurt with the honey, finely grated lime zest, finely grated orange zest and the liqueur. In a large bowl, beat the heavy cream until softly whipped. Gently fold in the honey-yogurt.
Cut the cake into squares and serve with dollops of the honey cream.
