I normally make a banana loaf in a loaf tin but recently got some silicon muffin thingies. Can I just simply put the mixture into the cases rather than the loaf tin? I can't see why not but there may well be a reason not to do it.
I make banana loaf using a recipe for a loaf tin and have often put the mixture in to silicone muffin cases (for kids pack ups) with no problem. Just decreased baking time if I remember correctly.
