- Oats – The quick cooking oats are the best option for this recipe. If you have the old-fashioned oats, you can use those as well.
- Flour – All purpose flour is your best bet for this recipe. When measuring the flour, make sure you spoon it into the measuring cup, and leveling the top off before adding it to the recipe.
- Sugar – White granulated sugar is one of the sugars you’ll need for this recipe.
- Half & Half – Half & Half is made of part heavy cream and part whole milk. This gives it a thicker consistency compared to milk, but a thinner consistency compared to heavy cream. However, you can substitute for just whole milk if you’d like.
- Brown Sugar – Brown sugar adds a lovely molasses flavor to this cake that I don’t recommend skipping out on.
- Butter – Use unsalted butter and make sure it’s softened. You can also substitute for unsalted margarine as well.
- Water – You’ll want boiling water for this recipe, that will help the oats soften a lot faster.
- Nuts – You can use any assortment of nuts you’d like or just one type of nut. Just make sure you give them a rough chop before using them in the topping.
- Spices – Cinnamon and nutmeg compliment this cake perfectly, don’t skip out on them!
Step By Step Instructions
- Start by grabbing a small bowl. Add the quick oats, then pour the boiling water over the oats. Let the bowl of oats soak for about 20 minutes.
- Preheat the oven to 350°F and grease a 13×9 inch pan with cooking spray or shortening. Lightly flour the baking dish. In a separate large bowl, add the flour, cinnamon, nutmeg, baking powder, soda and salt. Whisk the dry ingredients together until combined.
- In a separate large bowl, add the white sugar and 1 cup brown sugar, as well as 1/2 cup of the softened butter. Beat that together with an electric hand or stand mixer until it becomes well combined and fluffy. Add the vanilla extract and eggs and continue to beat that together until smooth. Once smooth, add the dry ingredients to the wet ingredients, as well as the soaked oats.
- Add the batter to the greased baking dish, and spread it out evenly with a spatula. Place it in the oven, and bake the cake for 35-45 minutes, or until a toothpick comes out clean when inserted into the center.
- While that bakes, start on the topping. Combine ⅔ cup of brown sugar, and ¼ cup of softened butter, and half and half with an electric mixer until a smooth, paste-like consistency. Fold in the coconut and chopped nuts until combined.
- Once the cake is done baking, take it out of the oven and change the oven setting to broil. Spread the topping over top of the warm cake, making sure it is even. Place the cake on the top rack of the oven, very close to the heat and let the topping broil for about 1-2 minutes until it starts bubbling. Remove the finished cake, and let it cool completely for an hour before slicing and serving.
