Preheat the oven to 325° F. Line a 6 inch cake pan (see notes) with parchment paper.
In a small mixing bowl combine the first 5 ingredients.
¾ cup Whole Wheat Pastry Flour, ½ teaspoon Baking powder, ⅛ teaspoon Nutmeg, ⅛ teaspoon Baking soda, ⅛ teaspoon Sea salt
In another small mixing bowl combine the rest of the ingredients except the sugar and egg.
⅓ cup Mashed ripe banana, ⅓ cup Plain Greek yogurt, 2 Tablespoons Olive oil, ½ teaspoon Vanilla extract
In a medium size mixing bowl beat the sugar and egg together on medium/high speed for about 2 minutes or until lightened in color and thickened.
½ cup Coconut sugar or Organic cane sugar, 1 large Egg
Add the banana mixture and stir gently a few times until partially combined. Then add the dry ingredients and stir just until combined.
Pour the batter into the prepared pan and bake for 37-41 minutes or until a toothpick inserted into the center comes out clean. Let cool for a couple minutes in the pan before turning onto a wire rack to cool.
Add your favorite frosting or topping and enjoy.
