Makes one 9” x 13" rectangle apple cake.
Preheat oven to 350° F (175° C)
Place wax or parchment paper on bottom of 9x13 glass cake pan, to avoid problems getting the cake out later. Lightly spray paper and sides with oil.
In a large bowl, mix the whole wheat flour, baking soda, baking powder, spices, and salt.
Soaked flaxmeal / ground flax
1 1/2 cups apple pieces (applesauce as sweetener)
Remaining cups of apple pieces / slices
Stir with a spatula in the large bowl, to get the wet and dry well mixed.
The dough will be very thick, but don't worry, because the apples will create juices when they bake.
To make the cake easier to get out, first line the pan with parchment paper, wax paper, or aluminum foil and then spray lightly with oil.
Smooth the batter flat with your spoon. It should be thick, not runny, but all the flour should be mixed in.
Bake in a preheated 350-degree oven. Check center is cooked, by waiting until a toothpick comes out clean.
Remove from oven, cool in the dish for at least 10 minutes. Pop the cake out, and continue cooling on a wire rack or towel.
Turn right side up before optionally frosting the top.
While cake is cooling upside down, make the frosting by blending the apple pieces in the food processor to make an applesauce.
Drizzle over a piece just before serving.
So the glaze doesn't seep into the cake, making it too soggy.
Sweetness: To make the cake sweeter, without adding sugar, consider adding 1/2 cup frozen bananas or water to the wet mix, then stir 1/2 cup raisins in when you add the wet to the dry.
