Grams Old Fashioned Oatmeal Cake
Me and my beautiful Grams circa ‘98

This cake has been a family favorite for decades. I remember many nights with my dad watching the food network while we waited for the icing to finish broiling on top of this delicious cake. It is a really fun dessert to make and is sure to please any house guests or hosts. It is also PAREVE which makes it amazing to bring to shabbat meals!

Making the Topping

  • Cream together the sugar, coconut and margarine.
  • Stir in the milk.
  • Poke holes into hot cake and pour icing over the top of the cake. (I use the bottom of a chopstick for this)
  • Set the oven to broil and broil the cake until the topping is bubbly.
  • Let cool and enjoy!


If you have one of those kosher for passover coconut cake mixes left over, you can totally use that as the cake base following this recipe but replacing the flour, white sugar, and baking soda with the cake mix.
