Preheat your oven to 350°F.
Start by making your flax eggs. In a small or medium bowl, mix together 1/4 cup ground flax and 10 tablespoons of water (which is 1/2 cup of water +2 tablespoons). Mix thoroughly and set aside to thicken.
Next start grating your carrots until you've got 6 packed cups of it. Put these into your stand mixer or a large bowl.
Cut all 4 sides off each of the apples and remove the stem and core/seeds. Carefully grate both apples and add them to your large mixing bowl.
Grate your fresh ginger until you’ve got 1/4 cup or so of it. Also add this to your mixing bowl.
Add the rest of the wet ingredients including your flax eggs, melted coconut oil and vanilla extract.
Stir up all of your wet ingredients until they are thoroughly mixed together.
Next, add all of your dry ingredients to your wet ingredients, including the tiger nut flour, cassava flour, brown sugar or stevia, pecan pieces, salt and baking soda. Mix your wet and dry ingredients together thoroughly.
Line your 9 x 13" baking dish with parchment paper and transfer your cake dough over into it. Using a wooden spoon or spatula, flatten out the cake dough until it is evenly distributed in the pan. Smooth out the top with a spatula.
For additional flavour, sprinkle more brown sugar onto the top of the cake. This is optional!
Bake the cake for 50 to 60 minutes or until a toothpick comes out clean. Baking time may vary between ovens.
