Banana Walnut cake (whole wheat)

A simple banana walnut cake!

Ingredients:

Whole wheat flour: 1 cup
Sugar: 1/2 cup
Vegetable oil: 1/4 cup
Ripe bananas: 2 large
Eggs: 2 large
Vanilla essence: 1 tsp.
Baking soda: 1 tsp.
Cocoa powder: 2 tbsp.
Beaten yogurt: 1/2 cup
Walnuts (chopped): according to taste

1. Pre-heat the oven at 200 C for about 20 minutes while you prepare the mix. 
2. Begin by sieving the whole wheat flour in a big mixing bowl. Sieve in cocoa powder and the baking soda. 
3. Mix everything slowly but really well so that there are no lumps remaining. Keep aside. 
4. In another big mixing bowl, add the sugar. Break the egg in the bowl and beat it well. Do not over mix. I used a hand whisk. 
5. Now add the well mashed bananas and again mix well. 
6. Add the oil, yogurt and vanilla essence. Mix everything slowly with the help of whisk. You can also use the electric mixer. 
7. Slowly begin to add the flour mix to this mix. Add a little at a time and keep on mixing but remember not to over mix. Just mix it until you see no lumps. The mix should be little flowy and not dense. 
8. Fold in the walnuts in the mix. Save some of the walnuts for the base if desired. 
9. Grease the cake mold and sprinkle little walnuts on the base if desired. 
10. Pour in the mixture. 
11. Bake for 30 minutes at 200 C. Then do the toothpick test. Insert a toothpick in the middle of the cake, it should not have the batter stuck to it, it should come out clean with little crumbles. If not done, bake for a little more time until the toothpick comes out clean.
12. Remove from the oven and let cool for about 10-15 minutes. 
13. Invert the pan and remove the cake from the mold in a tray or a plate. 
14. Let cool completely and cut in desired shapes. Enjoy!
