Banana Muffin and Cake

there's lots of recipes out there bout banana cake...as for this round, I've used premix as I've bought this earlier....so i follow on the instructions clearly but instead of muffin, i bake it as cake...bit too dry and too much poppy seeds..

Ingredients:
- 3 eggs
- 330gm ripe bananas (finely chopped)
- 150ml oil
- 500gm BANANA MUFFIN MIX (bought this premix from Bake With Yen)

Method:
- Place all ingriedients into mixing bowl and mix till just combined
- Spoon mixture into muffin mould/ tray
- Bake in preheat oven at 190C for 25 minutes (for the small ones, i bake them at 180C for 20 minutes, and the cake i baked at 190C for 45 minutes, should have set as 180C also)
- Let it cool completely before cutting the cake
