Banana Walnut Cake with Chocolate Chip Toppings

I've been wanting to better my maiden attempt at baking this cake so I thought "why dont I give it a shot today?"
And I did with my wonderful little helper, Rachel. :)
She enjoyed greasing the baking pan with butter, transfering pieces of chopped walnuts from the chopping board into a bowl, mashing the bananas and I guess the most enjoyable part is to sprinkle the cake with her favourite chocolate chips!!

Here's the recipe adapted from HHB's blogsite.

Banana Walnut Cake

Ingredients:

100g butter, soften at room temperature
160g caster sugar (i use 125g as my maiden attempt yielded a very sweet cake)
3 eggs, lightly beaten, room temperature
1 teaspoon pure vanilla extract
2 large ripe bananas, mashed (i use 3 medium sized "Ang Bah Jios")
210g plain flour
1 teaspoon baking powder
50g walnuts, chopped

Method:

1. Grease (with butter) and flour the sides of an 8" or 9" round pan and line the base with parchment paper.
2. With an electric mixer or a manual whisk, cream butter and sugar till light and fluffy.
3. Dribble in the eggs gradually and beat till incorporated in the batter. (The mixture may appear slightly curdled.)
4. Add vanilla extract and mashed bananas. Mix till smooth.
5. Sieve over flour and baking powder and mix till smooth.
6. Add chopped walnuts (reserve some for sprinkling the top, optional). Mix with a spatula.
7. Pour batter into prepared pan and smooth out the top with the spatula. Sprinkle the top with the remaining walnuts or arrange some banana slices (dipped in some lemon juice to prevent it from turning black) on top. (In addition, Rachel sprinkled her favourite chocolate chips!)
8. Bake in pre-heat oven at 180degC for 60 minutes or until a skewer comes out clean when inserted into the cake.
9. Leave the cake to cool in the pan for about 5~10 mins. Unmold and transfer to wire rack to let cool completely.
