Start by blending the oats until they become oat flour.
Add them to a large mixing bowl alongside the other dry ingredients: rice flour, salt, raisins, cinnamon, baking powder, and crushed walnuts.
Create the flax egg by mixing the flaxseeds and water. Set aside.
Peel and remove the seeds from the apple. Add it to the blender along with the dates, and coconut oil. Blend until smooth.
Add your flax eggs, the date mixture, and the grated carrot to a bowl and combine everything.
Add the wet ingredients to the dry ingredients and combine.
Place the batter into a baking dish. Spread evenly. Add some crushed walnuts on top and press them slightly into the batter.
Bake for about 35 minutes at 350 F/ 180 C.
Let it cool and cut it into squares/rectangles. Enjoy!
