Step 1

Preheat oven 350℉ (177 degrees C). Put an 8x8 baking pan with parchment paper and lightly grease, then set aside.

Step 2

Mix all the dry ingredients, such as oat flour, almond flour, ground flaxseeds, baking powder, cinnamon, and salt, in a large bowl and set it aside.

Step 3

In a medium bowl, add maple syrup, almond milk, and vanilla, stirring until thoroughly combined.

Step 4

Fold in walnuts, raisins, and apples together with wet ingredients.

Step 5

Now make a hole inside the dry ingredients and add the apple mixture. Stir with a spatula or spoon well until you have a smooth and thick apple batter.

Step 6

Pour the batter into the prepared pan and bake for 40-45 minutes, or until a fork or toothpick inserted in the cake's middle comes out clean.

Step 7

After the cake is prepared, let it cool for 20 minutes before taking it out from the pan.
