How to Make Grandma Nancy's Oatmeal Cake

  1. Preheat oven to 350°F (175°C). Grease and flour a 9x13 inch baking pan.
  2. Pour 1 cup boiling water over 1 cup rolled oats. Let stand for 5 minutes to soften.
  3. In a large bowl, cream together 1 cup (2 sticks) softened butter, 1 ½ cups granulated sugar, and ¾ cup packed brown sugar until light and fluffy. Beat in 4 large eggs one at a time.
  4. In a separate bowl, whisk together 2 ½ cups all-purpose flour, 1 teaspoon baking soda, 1 teaspoon baking powder, 1 teaspoon ground cinnamon, and ½ teaspoon salt.
  5. Gradually add the dry ingredients to the wet ingredients, mixing until just combined. Stir in the softened oatmeal and 1 teaspoon vanilla extract.
  6. Pour batter into the prepared pan and bake for 55-65 minutes, or until a wooden skewer inserted into the center comes out clean.
  7. While the cake is baking, prepare the topping: In a medium saucepan, combine ½ cup (1 stick) butter, ¼ cup milk, and ¼ cup granulated sugar.
  8. Bring to a boil over medium heat, then reduce heat and simmer for 1 minute. Stir in ½ cup rolled oats, ½ cup shredded coconut, and ½ cup chopped nuts.
  9. Spread the topping evenly over the hot cake immediately after removing it from the oven.
  10. Broil for 1-2 minutes, or until the topping is lightly browned. Watch carefully to prevent burning.
  11. Let the cake cool completely before slicing and serving.
