Just did this and Lyra inhaled it. From Tyler Florence
3 bananas
1 pint of blueberries (I used frozen and just let them sit out for a little bit on the counter)
Oven 350, place bananas with peels on on a rimmed cookie sheet, spread blueberries on sheet. Bake 20-25 minutes till blueberries are bursting.
I put down tin foil so I wouldn't be scraping BB's off of my cookie sheets. And I also keep all the BB's on one side and bananas on the other.
Let cool slightly then blend up in mixer/blender (bananas, blueberries and juice on the pan). Comes out this super dark purple, (can't wait to see the diaper tomorrow). I had 2 very ripe bananas and one regular banana so ours taste a lot like banana but even dh was eating it as he was feeding it to Lyra.
