We can use oats as they are but to make a less edgy smoother cookies we can ground them into flour.
Pour oat or oat flour into a bowl. Add bananas and the butter in too.
Put egg, honey and baking powder into the bowl, too. Work the dough together until we get an even mixture.
Use a spoon to place little lumps on the tray then flatten lumps into cookie form with the back of the spoon.
Slice strawberries or any other fruit then place the slices on top of each cookie. Strawberries will shrink and change color in the oven to the extent we won't win any visual award with them.
Put tray into the preheated 356°F / 180°C oven for 15 minutes to bake. Take the cookies out when they are golden brown.
