Banana Spice Cake

Preheat oven to 350 degrees F. Coat a 12-cup Bundt pan with cooking spray.

Sift flour, baking powder, baking soda, cinnamon, nutmeg, allspice, ginger, cloves and salt together into a bowl; set aside.

Heat butter in a small saucepan over medium heat, swirling the pan, until the butter turns a nutty brown. Pour the butter into a small bowl and let cool slightly.

Beat egg whites in a clean mixing bowl with an electric mixer on low speed just until frothy. Add cream of tartar, increase the speed to medium and beat until soft peaks form. Gradually beat in 3/4 cup sugar, 2 tablespoons at a time, just until firm peaks form; set aside.

Combine mashed banana, oil, orange zest, vanilla, egg yolk, the reserved melted butter and the remaining 1 cup sugar in a large mixing bowl; beat to combine. With the mixer on low speed, add the buttermilk and flour mixtures alternately in two additions each; beat just until blended. Add a heaping spoonful of the meringue and beat for just a few seconds to lighten the batter. Fold the remaining meringue into the batter by hand.

Pour the batter into the prepared pan and bake until a toothpick inserted into the center of the cake comes out clean and the cake is richly browned, 50 to 60 minutes. Cool in the pan on a rack for 10 minutes, then turn out onto the rack to cool completely. Before serving, dust the cake with confectioners' sugar.
