How to Make Classic Old-Fashioned Oatmeal Cake

Let’s break it down step-by-step.

Step 1: Soak the Oats

In a bowl, pour boiling water over the oats. Let sit for 15–20 minutes. This softens the oats and creates that signature moist texture.

Step 2: Make the Batter

Preheat oven to 350°F (175°C). Grease a 9×13-inch baking dish.

In a large bowl, cream together butter, brown sugar, and granulated sugar until light and fluffy. Add eggs one at a time, then stir in vanilla.

In a separate bowl, whisk flour, baking soda, cinnamon, and salt.

Add the dry ingredients to the wet mixture, mixing until just combined. Fold in the soaked oats (including any remaining liquid).

Step 3: Bake the Cake

Spread batter evenly into prepared baking dish.

Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.

Prepare the Topping for Classic Old-Fashioned Oatmeal Cake

While the cake bakes, mix together melted butter, brown sugar, cream, coconut, pecans, and vanilla.

Once the cake is done baking, remove it from the oven and spread the topping evenly over the warm cake.

Step 4: Broil to Caramelize

Place the cake under the broiler for 2–3 minutes, watching very carefully. The topping should bubble and turn golden brown.

Do not walk away — it can brown quickly!

Let cool slightly before serving.
