Pre heat oven to 180° celsius
In the bowl of a stand mixer, beat butter and caster sugar until light and fluffy
Add the eggs, banana and vanilla and mix until well combined
Sift the dry ingredients together
With the mixer on low, add the sifted ingredients, alternating with the buttermilk, until just combined.
Remove the bowl and gently stir through the chocolate chips
Pour the mixture into a prepared rectangular cake pan. I used a 23cm x 33cm pan and sprayed it with cooking oil, then lined with baking paper.
Bake for 25-30 mins, until a cake tester comes out clean
Allow to cool in pan for 5 minutes, before turning out onto a cooling rack, to cool completely
Top the cooled cake with cream cheese frosting and sprinkle with caramel pecans. You can also sprinkle over some extra cinnamon, if desired.
