Step-by-Step Instructions
Step 1: Soak the Oats
In a medium bowl, pour boiling water over the oats.
Let sit for 20 minutes to soften and cool. This gives the cake its signature texture.
Step 2: Preheat the Oven
Preheat your oven to 350°F (175°C).
Grease or spray a 9×13-inch baking dish and set aside.
Step 3: Mix the Cake Batter
In a large bowl, cream together the softened butter, brown sugar, and granulated sugar until smooth.
Add the eggs and vanilla, mixing well.
Stir in the soaked oats, including any remaining liquid.
In another bowl, whisk together the flour, baking soda, salt, cinnamon, and nutmeg.
Gradually add the dry ingredients to the wet mixture, stirring just until combined.
Step 4: Bake the Cake
Pour the batter into the prepared baking dish and smooth the top.
Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean.
Remove from the oven and set aside while you make the topping.
Step 5: Make the Topping
In a small saucepan over medium heat, melt the butter.
Add the brown sugar and milk, and stir until combined and bubbling gently.
Remove from heat and stir in coconut, chopped pecans, and vanilla.
Mix until evenly combined.
Step 6: Broil the Topping
Carefully spread the topping over the warm cake.
Place the cake under the broiler for 2–3 minutes, watching closely.
Broil just until the topping is bubbling and golden—do not walk away!
Step 7: Cool Slightly & Serve
Let the cake cool for about 15 minutes before slicing.
Serve warm or at room temperature. It’s especially delicious with a scoop of vanilla ice cream or a dollop of whipped cream.
Tips for the Best Oatmeal Cake
Soak the Oats – Don’t skip this step; it keeps the cake moist and fluffy.
