Eggless Coffee Cake

I wanted to make a yummy coffee cake for breakfast, and well, no eggs to be found! Found this recipe online (can't recall where!), and while I wouldn't say it was super moist, the flavours were quite nice - and it really is perfect w/ coffee.

For the cake:
4 cups whole wheat flour
1 tbsp baking powder
1 tsp baking soda
1 1/2 tsp salt
1 1/2 tsp cinnamon
1/4 tsp allspice
1/4 cup canola oil
1/2 cup vanilla soy yogurt (I used coffee cream yogurt - yum)
1 cup pure maple syrup
1 1/2 cups plain soymilk
1 tsp vanilla

For the topping:
1/4 cup whole wheat pastry flour
3 tbsp brown sugar
1/4 tsp cinnamon
1 tbsp canola oil
1 cup chopped walnuts (I used pecans)

Preheat oven to 350 F. Lightly grease or spray a 9x13 baking pan with non stick cooking spray.

Make the topping: Combine flour, sugar and cinnamon. Drizzle the oil in a little at a time and whisk until crumbs form. Add the walnuts and mix.

Make the cake: Combine dry ingredients in a large bowl. In a separate bowl, whisk together the wet ingredients until well combined. Add the wet to the dry and combine.

Pour the batter into the prepared pan and sprinkle the topping over it. Bake at 350 for 45 minutes or until a toothpick or butter knife comes out clean.
