Dark apple spice cake

Preheat oven to 350 degrees. Brush oil over the inside of a 10-inch bundt pan. Dust with flour and tap out the excess.
In a mixing bowl, whish together eggs, sugar and oil. In another bowl, stir together flours, cocoa, salt, cinnamon and allspice.
Using a rubber spatula or a wooden spoon, add the dry ingredients to the oil mixture alternately with the grated apples. Dissolve baking soda 1/4 cup hot water and stir into the batter. Stir in the raisins and nuts. The batter will be thick.
Spoon the batter into the prepared pan and bake for about 1 hour 10 minutes, or until the top springs back when touched lightly and a cake tester inserted in the center comes out clean.
Cool on a wire rack for 10 minutes before unmolding from the pan. Let cool. Sprinkle with sugar or serve with caramel sauce.
Caramel sauce:
In small heavy-bottomed pot, combine sugar and 1/2 cup water. Bring to a boil over medium-high heat, stirring occasionally. Cook, without stirring, for about 15 minutes, or until the syrup turns amber. (Take care not to burn it.)
Remove from heat and cool 2 minutes. Using a wooden spoon, stir in butter. Gradually stir in milk. Return to the heat and cook, stirring, for about 1 minute, or until caramel has dissolved. Stir in molasses and vanilla.
Serve warm. ( The sauce can be cooled, then stored, covered, in the refrigerator for up to 5 days. Warm slightly before serving.)
