Preheat Oven to 375 F (190 C). Place 6 large or 12 small muffin wrappers in muffin tray.
In bowl of stand mixer with whisk attachment, whip together mashed bananas, brown sugar, plum puree, eggs, vanilla and almond extract. (Medium-High Speed)
Using a separate bowl hand whisk together flour, salt, cinnamon, baking soda, and baking powder.
Spoon flour mixture into banana plum mixture continuing on medium high speed until well blended. (scrape sides and bottom of bowl as needed.)
Remove bowl from mixer and fold half of the chocolate morsels into the batter.
Spoon the batter into muffin wrappers. (3/4 full)
Top each muffin with extra chocolate morsels.
Bake for 15-18 minutes and golden brown or until toothpick in center comes out clean.
(you may get some melted chocolate on your toothpick and that's ok) (if you press your finger tips on muffin top and it springs back, they should be baked)
Place muffin tray on cooling rack for 5 minutes.
Remove muffins from tray and eat warm!
