Instructions

📝 Instructions:

Step 1: Prep
Preheat oven to 350°F (175°C). Line an 8×8-inch baking pan with parchment paper or lightly grease it.

Step 2: Mix
In a large bowl, mash the bananas until smooth. Stir in peanut butter until fully combined. Add oats (and vanilla if using). Mix until evenly incorporated. Fold in any optional add-ins.

Step 3: Press
Transfer the mixture into the prepared pan. Press down firmly with a spatula to create an even layer.

Step 4: Bake
Bake for 20–25 minutes, or until the edges are lightly golden and the center is set.

Step 5: Cool & Slice
Allow bars to cool completely in the pan (this helps them firm up). Slice into 9 squares and serve.

Notes

For Babies/Toddlers: Cut into small, soft pieces and use smooth peanut butter only. Always check for nut allergies.
No-Bake Option: Skip baking and refrigerate the pressed mixture for 2–3 hours until firm. (Texture will be softer.)
Without Peanut Butter: Substitute almond butter, sunflower seed butter, or mashed sweet potato for a nut-free version.
No Flour Needed: These bars are naturally flourless thanks to oats.
Storage: Store in an airtight container in the fridge for up to 5 days or freeze for up to 2 months.
