Notes

I add ⅓ flour mixture, then ½ the oat mixture, then another ⅓ flour, the other half of the oats, and finally the remaining ⅓ flour mixture. 
*Be sure to watch the cake closely when you are browning the coconut. If the cake is closer the to the flame or heating element in the oven it may brown very fast. Check it after 2-3 minutes and very often while it's under the broiler.
The topping isn't like the coconut pecan frosting that's on a German chocolate cake, it's thinner so it will ooze down into the cake.
