Banana Walnut Sponge Cake

I baked this last week when my girl was having her taekwondo competition and am baking it again because I have 3 eggs that I didn't break nicely for another kitchen project.

Also I had some over ripe banana that I needed to finish up fast.

Thus here is the banana walnut sponge cake baked especially for my hubby who didn't get to try.

For my previous experiment, the cake top was browned too quickly before the cake was ready so this time round, I cover the cake but I think I had done it way too early and thus, all the walnut and banana disappeared into the cake.

Verdict: The texture is soft and fluffy.  The banana taste is evident and with the added walnut, it gives the cake some crunch. 

Hubby's feedback was that it is a little more crumbly. 

Overall, this recipe is easy.


I found this recipe through my pile of printed but those days, it never occur to me to tag the source.  Please let me know who I should give credit to.
