Preheat the oven to 350 ° Fahrenheit. Grease sides and bottom of a 9-inch spring-form cake pan with cooking oil. Line the bottom of the pan with parchment paper and make sure to grease the top of parchment as well.
In a medium bowl, combine the whole wheat flour, almond flour, coconut sugar, baking powder, baking soda, salt and spices.
In a small bowl, whisk the 3 eggs with olive oil, maple syrup, and almond milk.
Gradually add liquid mixture to the dry ingredients and mix until there are no lumps.
Pour the batter into prepared pan. Arrange peach slices on top of batter in a single even layer with a little space between each. Sprinkle with extra coconut sugar, ginger and cinnamon if desired.
Place the cake pan in the oven and bake for about 40-45 minutes, or until toothpick or fork come out clean and the middle is set. Cool the cake on wire rack for 30 minutes before serving.
When cool, carefully remove side of pan. Serve with a sprinkle of powdered sugar and maybe a scoop of coconut whip cream.
