Line a small baking tray with parchment paper. Set aside.
Slice the bananas almost 1 inch (2,5cm) thick. Cover the top and bottom of the slices with peanut butter(almost 1,5 teaspoon in total). Place them on the parchment paper. Insert the lollipop sticks, making sure that they don’t go to the very bottom. Keep in the freezer for 2,5 hours, until the bananas and peanut butter are frozen.
When the bananas are frozen, melt the chocolate over bain marie: place the chopped chocolate into a heat proof bowl that sits over a pan of simmering water. Stir often. Remove the bowl from the heat when melted. Alternatively, you can melt the chocolate in the oven at 210°F (100°C) by placing the chopped chocolate into a heat proof bowl. You should check the oven often and stir when it starts to melt. If there are some pieces not melted, continue melting in the oven and stir again.
Remove the bananas from the freezer and gently remove the bananas from the parchment paper. If the peanut butter gets soft and the bottom of the peanut butter sticks to paper, it is very easy to stick it to the banana’s bottom again with a knife in 2 seconds.
Dip the bites into melted chocolate and gently tap the sticks on the side of the bowl to remove the excess chocolate. You should keep in the freezer for extra 2 hours or until the bananas are frozen again. Bananas become soft easily so remove the bites from the freezer when ready to eat.
