Preheat the oven to 180C/350F. Grease a 9-inch springform cake pan and set aside.
In a large mixing bowl, add the dry ingredients and mix well. Add the wet ingredients and mix until a thick and smooth batter remains.
Pour the batter into the greased cake pan and bake for 27-30 minutes, or until a skewer comes out mostly clean.
Remove the cake from the oven and let it cool completely, before adding the frosting.
* I used swerve brown sugar, but any granulated sweetener can be used.** For a healthy cream cheese frosting, beat 1 cup non-fat cream cheese with 1/4 cup maple syrup and 1 teaspoon cinnamon until light and fluffy.

If you'd like the cake to keep longer, store it in the refrigerator for up to 2 weeks.TO FREEZE: Place leftover slices of the cake in a ziplock bag and store them in the freezer for up to 6 months.
