Step 1

Preheat oven to 350°F. Grease and flour a 9x13-inch baking pan.

In a small, bowl, combine the oatmeal with the boiling water and let it sit for 20 minutes.

In a medium bowl, cream the butter, brown sugar, and white sugar.

In a small bowl, whisk the eggs and vanilla together.

In a large bowl, whisk the flour, baking soda, cinnamon, nutmeg, and salt together until well blended.

Add the egg mixture to the oatmeal mixture and stir until combined. Then add the sugar/butter mixture to the egg/oatmeal mixture and stir until combined.

Add the egg/oatmeal mixture to the flour mixture and stir until combined.

Pour into baking pan and bake about 30 to 35 minutes until golden brown and a toothpick comes out clean.

While cake is baking make the icing. In a medium bowl, cream the butter and brown sugar. Add the walnuts, coconut, and vanilla. If you need to thin the icing a bit, add the cream 1 tablespoon at a time.

Immediately after you remove the cake from the oven, adjust your oven to "broil". Spread the icing on the hot cake and pop it under the broiler until it's a bit brown and the coconut is toasted.

If possible, serve warm.
