Mix all the dry ingredients together. Make a well in the middle and add all the rest of the cake ingredients. Whip together until smooth.
Pour into a 9x13 inch oiled pan. Bake at 350º for 20 - 30 minutes, or until toothpick comes out clean.
While cake is baking, prepare glaze by heating maple syrup and nuts in a small saucepan over medium-high heat for 3-4 minutes. Add the coconut. Remove cake from oven and pour the glaze over the top, spreading carefully until the top is covered. Cool and serve.
