Ingredient Tips

For best texture, use very ripe bananas with brown spots.

Choose a protein powder that tastes great on its own to avoid bitter cookies.

All-natural peanut butter (just peanuts + salt) gives the best flavor and texture.

Substitutes and Variations

Vegan: Use a plant-based protein powder and swap peanut butter for almond or sunflower seed butter.

Nut-free: Swap peanut butter for sunflower seed butter.

Chocolate boost: Use chocolate protein powder and stir in sugar-free chocolate chips.

High-Protein: Add 1–2 tablespoons chia seeds.

Baked protein cookies.

Troubleshooting

Dough too dry? Add 1–2 teaspoons of almond milk or water.

Dough too wet? Add a tablespoon extra protein powder.

Not sweet enough? Add a teaspoon honey, maple syrup, or sugar-free sweetener.

Storage

Store cookies in an airtight container at room temperature for up to 48 hours.

Freeze baked cookies up to 3 months; thaw before serving.

Frequently Asked Questions (FAQs)
