Mix the flour, flax, chia, baking soda and salt in a bowl.
In another, larger bowl, whisk together the coconut flakes, maple syrup, honey, almond milk, mashed bananas and vanilla extract until well-mixed.
Add the flour in three batches, stirring in the flour thoroughly after each addition. When finished, add walnuts if using.
Pour into a bundt pan sprayed with oil (I just bought a silicone bundt pan which requires little to no oil, and the cake pops out beautifully without sticking). This is a thick batter, so smooth down the top before putting into the oven.
Bake in a preheated 350-degree oven for 45 minutes or until a toothpick inserted near the cake’s center comes out clean.
Cool thoroughly, de-mold.
