Total Time: 1 10

Servings: bars

1 cup protein powder*
½ cup ground flax seed
1 ½ cups old-fashioned rolled oats
3/4 cup peanut butter or your preferred nut or seed butter
1/3 cup honey agave, or real maple syrup
1 mashed banana
Pinch of salt
3/4 cup mix-ins: chopped dates dried fruit (such as blueberries, cranberries, or raisins), mini chocolate chips, unsweetened coconut flakes, nuts
2 teaspoons vanilla extract

In a large bowl, combine all the ingredients thoroughly, ensuring the mixture is smooth and holds together well. If the mixture feels too dry or crumbly, add a splash of water, milk, or an extra drizzle of honey until the consistency is just right.
Once everything is well mixed, transfer the mixture into an 8×8 inch pan, pressing it down firmly to ensure the bars hold their shape. Place the pan in the refrigerator and let it chill for at least one hour before slicing into bars.
Store these protein bars in the fridge, where they’ll stay fresh for up to two weeks.

Freezing Instructions: Layer the bars in a freezer-safe bag or container, placing a piece of parchment paper between each layer. Freeze for up to 3 months. Thaw in the refrigerator or on the counter before eating.
Protein Powder: Use your preferred protein powder—chocolate, vanilla, or plain varieties work well. You can also try using half protein powder and half unflavored collagen peptides.
Chocolate Protein Bars: For a chocolate twist, simply use chocolate protein powder.
Nut Butter: Swap peanut butter with almond butter, cashew butter, or sunflower butter as desired.
Vegan Protein Bars Recipe: Opt for your favorite vegan protein powder to make the recipe plant-based.
Gluten-Free Adaptations: Use gluten-free protein powder and gluten-free old-fashioned rolled oats. Clean Simple Eats Vegan protein powder is a great option.
