Failed Banana Cake :(

I bought a bunch of bananas last Tue, and don know what happened on Wed, the bunch of bananas dropped on the floor by themselves and I'd to keep them in the fridge.  As we gotta finish up those bananas fast, thus use the remaining bananas to bake this banana cake.

I adapted recipe from Joy of baking, with some adjustments which resulted a failure :p

Ingredients
230g all purpose flour
150g granulated white sugar (used brown sugar)
1 tsp baking powder
1/4 tsp baking soda
1/4 tsp salt
2 eggs, lightly beaten
113g unsalted butter, melted and cooled
3 ripe large bananas (approximately 454g), mashed well (used about 4, and additional 1 for garnish)
1 tsp vanilla extract

1. Preheat oven to 180C and place oven rack to middle position
2. Butter and flour the bottom and sides of a 9 x 5 x 3 inch loaf pan.  Set aside
3. In a large bowl, combine the flour, sugar, baking powder and baking soda.  Set aside
4. In a medium sized bowl, combine the mashed bananas (mash with salt), eggs, melted butter and vanilla
5. With a rubber spatula or wooden spoon, lightly fold the wet ingredients into dry ingredients just until combined and the batter is thick and chunky.
6. Scrape batter into prepared pan.  Bake until bread is golden brown and toothpick inserted in the center comes out clean, about 55 - 60 minutes.
7. Place on a wire rack to cool and then remove the bread from the pan.  Serve warm or at room temperature

I followed most ingredients and every steps accordingly until folding the banana mixture to the dry ingredients, I found the batter very dry and trying to be creative, I added 1/2 cup of milk, should go for 1/4 cup, just don know what I was thinking that day... sigh....  thus the ending result of the cake:

Instead of a buttery, fluffy type of banana cake, I got a oily and kuih type banana cake

Luckily, though the texture is funny, the taste is still good.   Lesson learned, do not simply add in too much milk :p
