apple crumb cake

You guysssss. I recently discovered Figgy Bakery, a gem of a blog/bakery, and have not been able to get enough of her recipes. They're an amazing take on whole foods and clean eating and she has a knack for making vegan baked goods and seemingly indulgent desserts just a bit healthier than they typically are. Anyways! I've made the below recipe a few times, modifying it a little each time, and this is what I've come up with:

Adapted from Figgy Bakery's recipe

Ingredients:

[topping:]  1/2 cup flour, 1 cup brown sugar, 1/2 cup sugar, 1/2 teaspoon salt, 2 

teaspoons cinnamon, 1 cup Earth Balance melted, 1/2 cup flour, 3/4 cup rolled oats

 [cake:] 3 cups chopped apple, 1 tablespoon cinnamon, 2 1/2 cups flour, 1 teaspoon baking soda, 3/4 teaspoon baking powder, 1/2 teaspoon salt, 3/4 cup Earth's Balance, 1 1/2 cups sugar, 2 eggs, 1 1/4 cups Greek yogurt, 1 teaspoon agave

Disclaimer: You need four separate bowls for this concoction 
as well as an 8x8 glass baking dish and perhaps a small loaf pan.

Begin with the topping. Melt Earth Balance (1 cup) in a medium-sized bowl. Add all other topping ingredients, mix and set aside.

Chop three apples into cubes, put into a bowl and add cinnamon. Set aside.

In another bowl, add flour, baking soda, baking powder and salt and mix.

In a fourth bowl, beat Earth Balance (3/4 cup) until smooth. Add sugar and mix. Then add the eggs and mix. Next, add the Greek yogurt and agave. Once all of these ingredients are incorporated, add the flour mixture, little by little, until all ingredients are thoroughly mixed together. Finally, fold in the apple-cinnamon combination and transfer to an 8x8 greased baking dish. You may have left over batter (I did), so I made an extra little loaf. 

Add the topping and bake on 350 degrees for about an hour, testing with a toothpick to make sure the cake is done.

Note: mine took probably an hour and fifteen minutes to cook. I'd recommend setting the timer for 50 minutes and checking periodically after that.
