How to Make Old Fashioned Oatmeal Cake

1. Soak the Oats

Place the rolled oats in a bowl and pour the boiling water over them. Let the mixture sit for about 15 minutes so the oats soften.

2. Prepare the Batter

Preheat your oven to 350°F (175°C) and grease a 9×13-inch baking pan.

In a large bowl, cream together the butter, brown sugar, and granulated sugar until smooth. Add the eggs and vanilla extract, mixing well.

3. Combine the Ingredients

Add the soaked oatmeal mixture to the batter and stir until combined.

In another bowl, mix the flour, baking soda, salt, and cinnamon. Gradually add the dry ingredients to the wet mixture and stir until a smooth batter forms.

4. Bake the Cake

Pour the batter into the prepared baking dish and bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Make the Coconut Topping

While the cake is baking, prepare the topping.

In a saucepan over medium heat, melt the butter and mix in the brown sugar and milk. Stir until smooth, then add the shredded coconut and pecans.

Spread the topping evenly over the warm cake.

Place the cake under the broiler for 2–3 minutes until the topping becomes bubbly and lightly golden.
