Apple Pie Cake (with a crunchy cinnamon sugar topping)

Apple pie is one of those American Desserts that makes you go 'yes please!'. I have always loved apple pie with the flaky crust and the gooey apple cinnamon filling. Well, I had no patience to make the pie crust and I wanted to have an apple pie. What is the next best thing to do? Yes, you try and make a cake that tastes like the apple pie.
While I was looking for pie crust recipes - I had stumbled upon this cake recipe. Something that had been on my mind but never got to the oven. I took inspiration from this recipe at 'Pinch of Yum'
I tweaked the recipe a bit in terms of the sugar I used (used a little less than mentioned) and the amount of apples I used too (used a bit more - just because I did not want to munch on raw apples). I also had an orange sitting on my table, so used the zest and the juice. Was not my intention to change the recipe......... lets just say.....it happened.
We loved the cake. It tasted good warm and cold. And we had it with a side of vanilla ice-cream on one occasion too.

Ingredients

1 cup brown sugar

1/3 cup vegetable oil

1 egg

1 cup buttermilk

1/2 teaspoon baking soda

1/2 teaspoon baking powder

1 teaspoon vanilla extract

2 1/2 cups All Purpose Flour

2 cups chopped apples

1 teaspoon allspice powder

1 teaspoon orange zest

4 tablespoons orange juice

1/2 cup sugar

1 tablespoon butter

1 teaspoon ground cinnamon

Method

Preheat the oven to 325 F and grease a 9X13 pan. 

Cut the apples into small pieces and add the orange juice to it (this will prevent it from browning). Sieve the flour, allspice powder, baking powder and baking soda together and keep aside. In a bowl, mix the brown sugar, oil, buttermilk and egg. No need to beat the mixture. To this add the vanilla extract and the orange zest and mix well. To this add the dry flour mixture and incorporate the mixture well. Add the chopped apples and incorporate everything well. I used a spatula to do this. Pour the batter into the 9X13 pan and spread it evenly using the spatula. 

Mix together the butter, cinnamon powder and sugar. Using your fingers spread this mixture on top of the batter very evenly. Pop it into the oven.

The recipe said bake for 45 minutes. Insert a toothpick and check for doneness. If it comes out clean, your cake is baked, if not, you need to bake for another 5 to 10 minutes. 

At 45 minutes my cake was still very raw. So, I had to bake for another 10 to 15 minutes. 

Remove from oven and cool a bit. Slice and serve warm with vanilla ice-cream or just like that.
