Ingredients Notes
Scroll through this section to view certain key ingredients we’re using in this Applesauce Oatmeal Breakfast Cake!
- Apples – You can use any kind of apples, I used McIntosh apples which are on the sweeter side. If you use Granny Smith, there will be a sour contrast to the cake. I had 2 cups total, and I sliced them into small cubes. I chopped them with the skin on, but you can peel it if you’d like.
- Applesauce – Make sure to use unsweetened applesauce, and not sweetened.
- Butter – This will be softened.
- Cornstarch – This helps add a tender crumb to the cake and keeps the apples from sinking to the bottom.
- Eggs – Make sure they’re at room temperature before beginning.
- Flour – All-purpose flour is used in this recipe.
- Oats - Make sure you use rolled oats, also known as large flake oats. Quick oats will not work.
Step by step instructions
Here is how to make and bake this applesauce oatmeal breakfast cake. You will need a 9×9 baking pan lined with parchment paper, 3 mixing bowls, a spatula, and an electric handheld mixer.
Step 1 – Prep. Grease the pan. For easy removal of the cake, place parchment paper on the bottom and 2 sides of the pan. Grease the other two sides and then set aside.
Step 2 – Mix dry ingredients. In a medium sized bowl, add in flour, oats, cinnamon, nutmeg, cornstarch, baking soda, baking powder, and salt. Stir to combine and set aside.
Step 3 – Cream the butter and sugar. In a large bowl, add softened butter and white sugar. Beat on medium speed for 2-3 minutes until it’s light and fluffy. Make sure to scrap the sides of the bowl.
Step 4 – Add in wet ingredients. Add in the eggs, vanilla, and applesauce. Continue mixing on medium speed. It’s okay if it is clumpy and curdled.
Step 5 – Add in dry ingredients. Mix in the dry ingredients and using a spatula, gently fold until a batter forms. Do not over-mix!
Step 6 – Add apples. Dice the apples into cubes. Then add into the bowl and mix in a few times.
Step 7 – Bake. Spread the batter into the prepared pan evenly. In a small cup, mix together sugar and cinnamon. Sprinkle that on top. This will give you a sweet crunchy top.
Bake the cake for 35-45 minutes. It really depends on your oven, but after 30 minutes I would start checking with a toothpick to see if it’s ready! A toothpick will come out clean when it's done baking.
Allow the cake to cool, slice, and enjoy! This applesauce oatmeal breakfast cake is soo good! It stays good on the counter for a day in an airtight container, and in the refrigerator for 5 days!
Expert Baking Tips
Here are a few expert baking tips from my kitchen to yours
- Use a gram scale. I cannot emphasize this enough! It is the most accurate way of measuring your ingredients in the kitchen. This is one of my favourites.
- Use fresh. Make sure to use fresh apples! Slice them into small cubes with the skin on or off, it's up to you!
- To make ahead of time: Bake, cool, slice, and store in an airtight container or wrap in foil/saran wrap.
FAQ
Can this cake recipe be doubled?
Yes, you can bake this cake in a 9×13 pan. The baking time will increase though. It should take anywhere from 40-55 minutes to bake. A toothpick inserted in the middle will come out clean when it's ready!
Do I have to add applesauce?
Technically this is an applesauce cake so yes for flavour! If you don’t want to add applesauce, you can replace it with room temperature yogurt, buttermilk, or kefir.
Can I bake this in an 8×8 pan?
Yes, but the cake will be taller and bake for longer.
Do I have to add oats?
No! Check out Applesauce Breakfast Cake for the recipe without oats.

Do you think I could sub GF 1:1 flour?
Ania says
Hi Gwen!
I haven’t tried this so I can’t say 100%. If you do want to try it out, I would recommend using a GF 1:1 flour as you mentioned since this already has gums in it that help with the binding of the batter. Best of luck!

I will be making your applesauce oatmeal breakfast cake for my ladies group brunch this-coming Saturday but I wanted to reply now with a thank you for listing the ingredients under each prep step! That's what I do when I copy recipes from websites; it's so much easier than having to scroll the page back and forth on my laptop. I'm looking forward to enjoying this cake soon.
Ania says
Hi Patty! It's my pleasure, so glad to hear the ingredient list helps. Enjoy the cake at your brunch! 🙂
Maria Garefalakis says
Well done! I made it twice, second time added a tiny bit of ground clove and a tiny bit of ground ginger. I substituted sugar with monk fruit sweetener and I topped the cake with crushed walnuts that I added to the sugar and cinnamon topping. OMG! Next I'm going to try substituting apple with pineapple 😃
Josie Tiencken says
Ania,
I have come across and made several of your recipes. They are all out of this world delicious and so simple to make and your recipes are so easy to read and understand!
I particularly appreciate how healthy the ingredients are and finally someone who does not put butter in everything!!
Thanks for sharing your talents with us. My family absolutely loves them all!!
Ania says
Hi Josie!!! Your comment made my night. I am SO happy to hear this and that you and your family love the treats. Thank you again for your kind words. Happy baking! 🙂
Kristine says
I made this and it is absolutely moist and delicious. I used whole fat buttermilk as I didn’t have any applesauce. However, it is very crumbly. What did I do wrong?
Ania says
Hi Kristine! I'm not sure why it came out crumbly if it was moist...perhaps the consistency of the buttermilk? I would suggest using less buttermilk next time if you can't use applesauce, maybe 1/2 cup, or use yogurt instead. I'm happy to hear it was delicious! 🙂
Teri otis says

Ania says
Hi Teri! I'm so happy this cake was a success and hope your garden club enjoys it!
