Preheat your oven to 350°F (175°C) and line a baking sheet with parchment paper or a silicone baking mat.
Mash the 3 large bananas in a large mixing bowl until smooth.
Add the 1/2 cup of peanut butter to the mashed bananas and stir until well combined and creamy.
Stir in the 2 cups of rolled oats until fully incorporated.
Fold in 1/4 to 1/2 cup of candy buttons gently to ensure even distribution.
Using a cookie scoop, portion the dough onto the prepared baking sheet, leaving space between each.
Bake for 12-15 minutes until edges are golden brown and centers are set.
Let cool on the baking sheet for a few minutes before transferring to a wire rack.
