Make this gluten-free easy oatmeal blueberry cake for a quick grab-and-go snack, make ahead breakfast or just as a tea/coffee companion. There’s no flour involved, as the main ingredients you will need are oats, blueberries, eggs, coconut oil, yogurt and some dark brown sugar. You’ll also need a small (8-9″) pan and some baking paper.

This flourless oat blueberry cake is kid-friendly too. And it gets some more bonus points because to me, this is the effortless way to make flourless blueberry muffins. Why? It’s way easier to clean one large cake pan than a muffin pan. But, maybe it’s just me!
Now let’s get into it!

Easy Blueberry Oatmeal Cake Ingredients
- oats
- coconut oil or butter
- yogurt
- dark brown or coconut sugar
- baking powder
- vanilla
- eggs
- some nuts (optional)
- fresh blueberries (do not use frozen in this one – unless you thaw and drain them before)
How To Make The Blueberry Oatmeal Cake
As mentioned – it’s easy!

All you need to do is put all the ingredients for the batter (except for blueberries) into a blender or blend using a hand blender and a bowl.
Let the mixture sit for about 10 minutes. Stir in half of the blueberries, reserve some for topping.
Pour the mixture into a baking pan, lined with parchment paper.

Add the rest of the blueberries (and nuts if you desire I used pistachios).
Then bake at 190C/370F for about 18-22 minutes or until golden brown and the toothpick comes out clean when inserted in the middle (preferably not into a blueberry!)

Let cool, slice and enjoy!
How To Enjoy
The cake will become your favorite coffee or tea’s best friend.
We enjoy it as is, but if you’d like you can do a quick frosting using cream cheese, vanilla and some maple syrup. Just mix 2-3 tbsp of cream cheese with the vanilla, then add maple syrup to taste (start with 1 tsp).
