Ingredients

  • 1/2 cup vegetable shortening, such as Crisco, plus more for greasing the dish
  • 1 1/3 cups all-purpose flour, plus more for dusting the dish
  • 1 1/4 cups hot water
  • 1 cup old-fashioned rolled oats
  • 1 3/4 cups packed light brown sugar
  • 1 cup granulated sugar
  • 2 large eggs
  • 1 teaspoon baking soda
  • 1 teaspoon ground cinnamon
  • 1/2 teaspoon salt
  • 6 tablespoons (3/4 stick) unsalted butter
  • 1 tablespoon evaporated milk
  • 1 cup chopped pecans
  • 1 cup sweetened coconut flakes

Method

  • Preheat the oven to 350F.
  • Lightly grease and flour a 9 x 13-inch casserole dish.
  • In a small bowl, pour the hot water over the oats and let sit for 10 minutes for the oats to absorb the water.
  • Cream together 1 cup of the brown sugar, granulated sugar, and 1/2 cup of the shortening in a large bowl.
  • Add the eggs and stir well.
  • In a separate bowl, sift together the 1 1/3 cups flour, baking soda, cinnamon, and salt.
  • Add the dry ingredients to the butter mixture, and stir well.
  • Add the softened oats a little at a time, stirring after each addition, until all of the oats are incorporated.
  • Pour the batter into the prepared casserole dish.
  • Bake for 30 minutes or until a toothpick inserted into the center of the cake comes out clean.
  • Transfer the cake to a wire rack and let cool completely.
  • Preheat the broiler.
  • For the icing, put the remaining 3/4 cup brown sugar, the butter, evaporated milk, and nuts in a saucepan set over medium-high heat and bring to a boil.
  • Boil for 1 minute.
  • Remove the pan from the heat and add the coconut.
  • Ice the cake, transfer it to the oven, and broil for 3 to 5 minutes or until the icing is golden brown.
  • Watch the cake very carefully as the icing can burn easily.
  • Cut into square pieces and serve immediately.
  • Store any leftover pieces in an airtight container and refrigerate for up to five days.
