Preheat your oven to 350°F (175°C) if you prefer a warm dessert or meal prep.
In a mixing bowl, combine the rolled oats, almond butter, mashed bananas, cocoa powder, and vanilla extract. Mix until well combined.
Fold in the chopped nuts, dried fruit, and a pinch of salt to the mixture.
Line a baking pan with parchment paper or grease it lightly to prevent sticking.
Pour the mixture into the prepared pan and press it down evenly with the back of a spoon or spatula.
Bake in the preheated oven for about 10 minutes for a warm treat, or refrigerate for an hour if you prefer it chilled.
Once cooled, cut into squares and enjoy!
