Ah, back in the days when I was a new mother, I had to come up with creative ways to use all the extra baby food I had lying around that my young daughter refused to eat. After several attempts, I finally came up with this version.
Mix together sugar and butter in a microwaveable dish and cook on HIGH heat just long enough for it to soften up- maybe 30 seconds, but not to melt it completely.
Remove and stir to combine.
Mix together baby food, over-ripe bananas, lime juice, eggs,vanilla,extract, and buttermilk.
Mix in the butter mixture gradually, so as not to cook the eggs.
It will look a little curdly from the lime juice- this is normal and will go away upon baking.
Combine all dry ingredients together in a large bowl, then add the wet mixture and stir with a wooden spoon just enough to combine the ingredients and moisten them- pressing out any big lumps with your spoon (don't overmix).
Pour into a greased and floured loaf pan (9x5") and bake in a preheated oven at 350 F (180 C) for about an hour or until a toothpick tests clean.
Let cool completely before serving or it will fall apart.
