Preheat your oven to 180°C and line a small baking dish with parchment paper or use a silicone baking pan.
Mash the ripe bananas in a bowl until smooth.
Add peanut butter, and vanilla extract. Mix until fully combined.
Stir in rolled oats, pumpkin seeds, sunflower seeds, chopped dark chocolate. Also add in the sweetener of choice if preferred. I often add in 10 grams of sukrin gold, but other sweeteners work too.
Combine everything until a thick, sticky mixture forms.
Spread the mixture evenly into the lined baking dish and press down firmly.
Bake for about 20 minutes at 180°C until golden and set.
Let cool completely before slicing into bars.
