In a medium bowl, whisk together the coconut flour, baking powder, cinnamon, nutmeg, and salt. Set aside.
In the bowl of a stand mixer, combine sweetener, oil, apple tea, eggs, and vanilla. Mix to combine. Then add the flour mixture and combine once again. Pour into prepared Bundt pan and bake for 1 hour, or until a toothpick comes out of the cake clean.
While it bakes, prepare the glaze. In a medium-sized bowl, place the 1/2 cup brewed tea, 1/2 cup coconut oil (it will melt in the hot tea), and Natural Sweetener and mix well. Set aside to cool a bit before spreading over cake.
Cool the cake in the pan for 10 minutes, then invert onto your serving platter. Top with glaze. Another option for serving this cake would be to finish it with a simple dusting of powdered sweetener once it is cool. A dollop of slightly sweetened whipped cream or a scoop of “healthified” apple crisp ice cream!
