A Banana Cake NIghtmare

Why in the world is it so hard to bake a cake? You would think baking a cake is like riding a bike, once you master it then it stays with you for life, right? Well, not exactly.

Vivid childhood memories come bursting thru my brain as tears are about to start pouring from my eyes. Why? why?why? I don't understand.  I used to bake beautiful cakes when i was 12, 13, 14....16 then life caught on, we moved to New York, and all of a sudden there were real things to worry about, like learning English for  instance.  There was no more time for baking...... oh and the discovery of ready to bake cookie dough.... that really changed everything.  

Then one day, 17 years later I decided to bake a cake, just for fun.  To relax from the worries of everyday life, to once again be able to close my eyes and have a taste of the sweetness of those careless years where all things were possible and life was a basket of surprises waiting unfold before my curious eyes. Oh! what a rude awakening.

Can someone please tell me where did I go wrong?

So I started by gathering all ingredients

Then followed all  instructions as per Rosemary's Banana & Walnut cake recipe:

Banana Walnut Cake

Ingredients

100 grs Butter

150 grs Brown Sugar

50 grs Milk ( I used almond milk)

1 egg

4 medium bananas

220 grs self-rising flour (I added 1 tsp of baking powder to regular)

60 gms of coarsely chopped walnuts.

Preparation:

Preheat oven to 350F (180C).

Add butter, sugar and milk to TM cup and program 1min/37C/speeed2

Place butterfly in the cup add egg and program 3min/37C/speed 3

Remove butterfly, add the bananas, and program 5 sec/speed 6

Add flour 15sec/vel 3.

Slowly incorporate walnuts with spatula.

Pour dough into a previously greased and floured baking pan.
Oven bake for 40-50 min

Nothing could have gone wrong except for the result.  Very disappointing.

For some reason it did bake inside, even after 50 min of baking in a 350 degree oven (and yes it was 350 because i even went out and got a oven thermometer.

The dough's consistency seemed perfect, so i don't really thing the problem is the recipe. What in the world happened?

End result. cake went straight to the trash :(
