Ingredients

Scale
  • 1 cup old-fashioned rolled oats
  • 1/2 cup butter
  • 1 1/2 cups boiling water
  • 2 large eggs
  • 1 cup light brown sugar
  • 1 cup granulated sugar
  • 1 1/3 cups all-purpose flour
  • 1 teaspoon ground cinnamon
  • 1 teaspoon baking soda
  • 1/2 teaspoon ground nutmeg
  • 1/2 teaspoon salt
  • 6 tablespoons butter, softened
  • 1 cup shredded sweetened coconut
  • 1/2 cup evaporated milk
  • 1/2 cup light brown sugar
  • 1 cup chopped nuts
  • 1 teaspoon vanilla extract

Instructions

  1. Preheat the oven to 350°F (180°C). Grease a 9×13-inch baking pan.
  2. Place the oats and butter in a bowl. Pour the boiling water over them, stir, and set aside to soften.
  3. In a large mixing bowl, beat the eggs with the brown sugar and granulated sugar until well combined.
  4. In a separate bowl, whisk together the flour, cinnamon, baking soda, nutmeg, and salt.
  5. Add the dry ingredients to the egg mixture and stir until just combined.
  6. Stir in the oatmeal mixture until the batter is smooth.
  7. Pour the batter into the prepared pan and bake for about 35 minutes, or until a toothpick inserted in the center comes out clean.
  8. While the cake bakes, mix all topping ingredients in a bowl until well combined.
  9. Remove the cake from the oven and switch the oven to broil. Spread the topping evenly over the warm cake and return it to the oven. Broil for 2–4 minutes, watching closely, until the coconut is golden brown.
  10. Remove from the oven and allow to cool slightly before serving.

Notes

For an extra moisture boost, consider adding a mashed banana to the batter. You can swap out nuts based on your preference.
