How to Make It
Heat oven to 350° F. Oil a 9-inch round cake pan, line the bottom with a parchment circle, oil again, and dust with flour, tapping out the excess.
In a large bowl, whisk together the flour, baking soda, cinnamon, cloves, and salt. In a medium bowl, whisk together the oil, molasses, brown sugar, egg, ginger, and ½ cup boiling water. Add to the flour mixture and whisk until just combined (do not overmix). Fold in the apples.
Transfer the batter to the prepared pan and bake until a toothpick inserted in the center of the cake comes out clean, 40 to 45 minutes. Cool in the pan for 30 minutes, then turn out onto a rack to cool completely. Before serving, dust with the confectioners’ sugar.
