These wholesome breakfast bars combine mashed banana, creamy peanut butter, and maple syrup with hearty gluten-free oats for a nutritious morning treat. Studded with sunflower seeds, dried fruit, and walnuts, they offer satisfying texture and natural sweetness. Perfect for busy mornings, lunchboxes, or post-workout fuel. The flax egg keeps them plant-based while adding omega-3s, and the bars hold together beautifully for grab-and-go convenience. Naturally sweetened and packed with fiber, they provide sustained energy without the crash of processed breakfast options.

Tips
Use very ripe bananas with brown spots for maximum sweetness and easier mashing. Under-ripe bananas won't mash smoothly and provide less natural sugar.
Let the flax egg sit for the full 15 minutes to thicken properly - this acts as the binding agent that holds the bars together.
Don't overbake as the bars will continue cooking slightly while cooling. Look for light golden edges rather than browning throughout.
Good to Know
Store covered at room temperature for up to 3 days or refrigerate for up to 1 week. Wrap individually for grab-and-go convenience.
Can be made up to 3 days ahead. Bars actually improve in texture after resting overnight as flavors meld.
Serve at room temperature. Great with coffee, tea, or a glass of milk for a complete breakfast.
Common Mistakes
Don't skip cooling time or bars will crumble when cut
Ensure flax egg is fully set before using to prevent crumbly texture
Press mixture firmly into pan to avoid bars falling apart
