I'll admit that I messed this up a bit trying to cook it for the first time, but I managed to preserve the flavor (just not the appearance). It was delicious! I actually used a homemade loaf of orange-cranberry bread when I cooked it. I also added a bit of brown sugar to the banana puree. Easy enough for my 8-year-old son to help me with it.
I created a minor adaptation of this recipe, which was absolutely terrific.
I omitted the cinnamon (I think it'd be delicious, but thought our young kids might not like it).
In a small saucepan, I added chopped walnuts to maple syrup, and put it on the stove over very low simmer heat. When the french toast was ready, I topped with powdered sugar and sliced bananas, then the walnut syrup. Fantastic result. Kids and adults all enjoyed it for brunch. Pair with fruit cup, coffee, etc. and you're all set a weekend brunch.
