In a frying pan combine chopped apples and maple syrup. Cook on a medium flame for few minutes. Then add vanilla extract. Stir and let it cook until apples are soft and mushy. Turn off the flame and let it cool.
In the meanwhile, in a small bowl combine flax meal and water and stir. Let it soak until it thickens slightly.
Preheat oven at 325 degree Fahrenheit and prepare a round 8 inch baking pan by greasing it.
In a large mixing bowl combine almond flour, baking powder, baking soda and salt. Mix well with a spoon making sure there are no lumps and the dry ingredients are well mixed.
In another bowl spoon the cooked apples along with the syrup and mix in soaked flax meal. Stir vigorously until well blended.
Now, Pour the wet ingredients into the dry ingredients and roughly whip up the batter.
Lastly, when all the ingredients are well mixed pour in almond milk and whip with a spatula very nicely. The batter would be thick and sticky. Now, spoon the batter at the center of the baking pan and tap the pan on a flat surface to evenly spread the batter.
Place the baking pan in the middle rack of the oven and bake for 30 minutes. After 30 minutes test the cake with a toothpick. If the toothpick comes out dry shift the baking pan at the bottom rack of the oven and let it bake again for 5 minutes to get the nice brown color and firmer from the inside. (Do not over bake).
Take out the pan and let it cool. Serve warm or at room temperature. It pairs well with vanilla ice cream as well.
