Preheat oven to 350° Fahrenheit and grease a baking dish really well (use a 9x9" glass pan or round pan about the same size). Chop apples and set aside.
In a large mixing bowl whisk together the almond flour, tapioca flour, cinnamon, cardamom, salt and baking powder.
Mix in the rest of the cake ingredients, except the apples with a spoon until thoroughly combined.
Fold in apples and pour into greased dish. Spread out into an even layer.
Combine all of the topping ingredients in the bowl you just used and then sprinkle on top of the cake mixture.
Transfer to the oven and bake for 50-55 minutes, until a toothpick comes out clean. Let cool completely before slicing and serving. This apple cake would be great with caramel sauce drizzled on top as an optional topping.
