• 1/4 cup unsalted butter, melted
• 1/2 cup brown sugar

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

✔ Don’t overmix the batter – Stir just until combined to keep the cake light and fluffy

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

How to Store Your Oatmeal Cake

• At room temperature – Keep in an airtight container for up to 3 days
• In the fridge – Store for up to 5 days. Let it come to room temperature before serving
• To freeze – Wrap slices in plastic wrap and store in a freezer-safe bag for up to 3 months. Thaw overnight before serving

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
