How to Make Oatmeal Cake

1. Prepare the Oats

In a bowl, combine the oats and boiling water. Let them sit for 15 minutes so they soften and absorb the liquid

2. Mix the Dry Ingredients

In another bowl, whisk together the flour, cinnamon, baking soda, salt, and nutmeg. Set aside

3. Cream the Butter and Sugars

In a large mixing bowl, beat the butter, brown sugar, and granulated sugar until light and fluffy. This step helps create a soft cake
Add the eggs one at a time, beating well after each addition. Stir in the vanilla extract

4. Combine Everything

Mix in the softened oatmeal mixture
Gradually add the dry ingredients, stirring until just combined. Don’t overmix—this keeps the cake tender

5. Bake the Cake

Preheat your oven to 350°F (175°C)
Pour the batter into a greased 9×13-inch baking pan
Bake for 30–35 minutes, or until a toothpick inserted in the center comes out clean

6. Make the Topping (If Using)

While the cake bakes, combine the coconut, nuts, melted butter, brown sugar, and cream in a small saucepan. Cook over medium heat until bubbly

7. Broil the Topping (Optional)

Spread the topping over the warm cake
Place under the broiler for 1–2 minutes until golden and caramelized. Keep a close eye—it can burn quickly

What to Serve with Oatmeal Cake

A hot cup of coffee or tea – The cake’s warm spices pair beautifully with a cozy drink
Vanilla ice cream or whipped cream – A scoop of ice cream adds a creamy contrast to the cake’s texture
Fresh berries – Serve with sliced strawberries or raspberries for a pop of freshness

Tips for the Best Oatmeal Cake

✔ Let the oats fully soak – This step is key for a moist cake

✔ Use room temperature ingredients – This helps everything blend smoothly for a better texture

✔ Want extra flavor? Add ½ teaspoon of ground ginger or cardamom for a deeper spiced taste

Frequently Asked Questions

Can I use quick oats instead of rolled oats?

I don’t recommend it—quick oats absorb liquid differently and can make the cake dense. Stick with old-fashioned rolled oats for the best texture

Can I make this cake gluten-free?

Yes! Substitute the all-purpose flour with a 1:1 gluten-free baking blend. Just make sure your oats are certified gluten-free

Do I have to add the topping?

No, but it adds a delicious caramelized crunch! If you prefer a simpler cake, you can skip it or just dust the top with powdered sugar

Can I add raisins or chocolate chips?

Absolutely! Fold in ½ cup of raisins, chocolate chips, or even diced apples for an extra treat
