How to Make Easy Apple Oatmeal Cake Recipe

Step 1: Preparing Your Apples

Start by peeling your Granny Smith apples. Then cut one into small cubes and shred the other. Mixing these two textures gives your cake a beautifully varied bite — the cubes provide tender pops of apple, while the shredded apple blends into the batter, adding moisture. Toss them gently with 1/4 teaspoon of cinnamon to infuse even more warm spice flavor before setting them aside.

Step 2: Mixing the Dry Ingredients

In a medium bowl, whisk together your flour, rolled oats, baking powder, baking soda, cornstarch, salt, cinnamon, and any optional spices like allspice, cloves, or nutmeg. This step is crucial since evenly combining these ingredients ensures your cake bakes with consistent texture and perfectly distributed warm flavors.

Step 3: Whisking the Wet Ingredients

Grab a large bowl and whisk together the oil, unsweetened applesauce, light brown sugar, vanilla, and eggs for 2 to 3 minutes until the mixture is smooth and creamy. Giving it this extra attention here helps incorporate some air, which leads to a lighter cake crumb.

Step 4: Bringing It All Together

Gently fold the dry ingredients into the wet mixture using a spatula. Remember, folding gently is key here to avoid over-mixing, which can make the cake tough. Once the batter looks just combined, carefully fold in the prepared apples, keeping that tender texture intact.

Step 5: Adding the Finishing Touch and Baking

Pour the batter into a parchment-lined pan and smooth the top. Mix the white sugar with cinnamon, then sprinkle it evenly over the batter. This sugary topping will bake into a sweet, crunchy crust that perfectly balances the soft interior. Bake at 350℉ (180℃) for 40 to 50 minutes, checking with a toothpick for doneness — when it comes out clean, your cake is ready!

Make Ahead and Storage

Storing Leftovers

Once completely cooled, store any leftover cake tightly covered at room temperature for up to 2 days. After that, it’s best kept in the refrigerator, where it will stay fresh for up to 4 days without drying out.

Freezing

Easy Apple Oatmeal Cake Recipe freezes beautifully! Wrap individual slices or the entire cake tightly in plastic wrap and then in foil to prevent freezer burn. It can be frozen for up to 3 months — just thaw overnight in the fridge before enjoying.

Reheating

To warm leftovers, gently reheat slices in the microwave for 20 to 30 seconds or in an oven preheated to 300℉ (150℃) for 10 minutes. The warming process brings back that freshly baked softness and revives the fragrant spices perfectly.

FAQs

Can I use a different type of apple for this cake?

Absolutely! While Granny Smith apples provide a nice tartness that balances the sweet cake, you can substitute with Fuji, Honeycrisp, or Gala apples depending on your taste preference. Just remember that sweeter apples might make the cake more sugary overall.

Is it possible to make this Easy Apple Oatmeal Cake Recipe gluten-free?

Yes! Simply swap the all-purpose flour for a gluten-free all-purpose blend that includes xanthan gum for best results. Make sure your oats are certified gluten-free if you want the cake to be completely gluten-free.

Can I replace the oil with butter?

You can, but I recommend using melted butter rather than solid to maintain the moist texture. Butter will also add a richer flavor and a slightly denser crumb, which is delicious if you prefer that.

How can I make the cake more moist?

Using the applesauce in this recipe already helps keep the cake wonderfully moist. For extra moisture, you can add a tablespoon or two of yogurt or sour cream to the wet ingredients, but be careful not to alter the batter consistency too much.

What’s the best pan size to use for this cake?

A 9×9-inch square pan or an 8-inch round pan works best for this Easy Apple Oatmeal Cake Recipe. It ensures the cake bakes evenly and develops a lovely crust while staying soft inside.
