Step-by-Step Instructions
- Prepare Your Pan and Oven:
- Line a small baking pan with parchment paper for easy lifting and minimal sticking. Preheat your oven to 180C or 350F so it is hot and ready for baking.
- Blend Most Ingredients:
- Place all the ingredients except about one quarter of the oats into a blender or a large bowl. If using a hand blender process everything until completely smooth. This gives the cake a soft even crumb.
- Add Remaining Oats:
- Stir in the leftover oats gently to add just a little chew and hearty texture to the batter.
- Pour and Decorate:
- Pour the smooth batter into your prepared baking pan. For an extra touch layer thin slices of apple or sprinkle a few extra oats over the top.
- Bake:
- Place the pan in your hot oven and bake for twenty to thirty minutes. The cake is done when a toothpick inserted into the center comes out clean and the top looks lightly golden.
- Cool and Store:
- Let the cake cool in the pan before slicing. For the best texture refrigerate covered for at least an hour. This helps flavors develop and makes slicing easier.

My favorite part is scooping up those golden corners that get a little chewy from the oats. One time my son helped sprinkle cinnamon on top and the whole kitchen smelled like a cozy fall morning.
Storage Tips
This cake gets even better with time. Store slices in an airtight container in the fridge for up to four days. You can also freeze individual pieces tightly wrapped for two months. Let them thaw in the fridge overnight or warm gently in the oven for a freshly baked taste.
Ingredient Substitutions
You can use dark brown sugar or maple syrup in place of honey for a different twist. Coconut oil makes this cake dairy-free if you need. Feel free to swap in a dairy-free yogurt or Greek yogurt based on your tastes and dietary needs.
Serving Suggestions
