Healthy Breakfast Oatmeal Apple Cake

I really don’t have much to say about this oatmeal apple cake. In the words of Gordon Ramsey, it’s “f***** delicious”. I don’t know if there were enough stars to bleep that bad bad word. 

Other than being delicious this flourless cake is also a great use of old apples. If you’re like me, you’d always buy apples and never eat them. You know that saying…

An apple a day…

Then you almost bite a piece off and ”Oh, look it’s rotting”. 

Or you’ll have a toddler who wants that apple and then just abandons it after one bite like it’s an old snot-filled tissue. 

But you’re not gonna throw that apple away. No, no. you have to save it, to save the environment and because people somewhere might want to eat an apple, but they don’t have any. 

So you slice those old apples, cut the bad parts out, and save the good ones for rainy days. Except, you don’t keep them, but decide to make them into pancakes, cookies, apple pie or this cake. Yes, this easy apple cake is a great option.

How To Make Breakfast Apple Cake

It’s pretty easy if you have a hand blender. It might also work in a high-speed blender too. You add all the ingredients to a bowl or a blender cup and process them until smooth. Add some more whole oats in the end.

You can top the cake with more oats or even thin apple slices for decoration before baking. Last time I also added some apple chunks to the batter.

Ingredients

  • 1 cup oats
  • 1 large apple, peeled and chopped
  • 3 Tbsp honey*
  • 1 tsp vanilla
  • 1 tsp cinnamon
  • 1/2 tsp baking soda
  • 1/2 tsp baking powder
  • 3 tbsp yogurt
  • 2 eggs
  • 1 Tbsp butter or coconut oil

Instructions

  1. Preheat the oven to 180C/350F.
  2. Put all ingredients in a blender or in a bowl to process with a hand blender, but use only 3/4 of the oats. Process until smooth and then mix in the 1/4 of the oats.
  3. Line a smaller sized baking pan with parchement paper and pour the mixture inside.
  4. Bake for 20-30 minutes or until a toothpick comes out clean.
  5. After baking let the cake cool off, slice, put the slices in an airtight container in the fridge for at least an hour. The cake gets better the longer it’s cooled. Enjoy for breakfast or dessert.

Notes

*Since I ran out of honey and maple syrup, last time I used about 3-4 tbsp of dark brown sugar and it was delicious! Make sure to do a quick taste test to know whether the cake is sweet enough for you. I also used a smaller baking pan this time - that's why it looks fluffier in the pictures.
