Preheat your oven to 350 degrees

Take 1/4 of a banana, mash it, and set it aside

Mix peanut butter, oats and vanilla in a bowl

Add the banana to the oat mixture

Line a cookie sheet with foil or parchment paper

Butter your fingers (so that the mixture doesn't stick to your hands) and take some of the mixture and put it on the foil and flatten it out and do it till you're out of mixture. Put the sheet in the oven!

OR!! You can shape them as a normal cookie and put them in the freezer. They need an hour and then you can take them and set them on the counter. (I like them fresh out of the freezer for a frozen treat for the summer)

Side note: You can add dark chocolate chips, raisins or even nuts if you're feeling it! You DONT have to bake it! You DONT have to flatten them out, you could just press on the ball of dough a little, if you prefer a thick cookie! Enjoy!
