Instructions

Prepare the pan: Line an 8-inch square baking pan with parchment paper, leaving some overhang for easy removal.
Mix the wet ingredients: Add peanut butter, honey or maple syrup, and vanilla extract to a bowl. Stir until smooth and well combined.
Add the dry ingredients: Mix in the rolled oats, protein powder, ground flaxseed, and salt.
Adjust the texture: If the mixture feels too dry or crumbly, add milk 1 tablespoon at a time until it becomes thick and easy to press together.
Add chocolate chips: Fold in the mini chocolate chips if using.
Press into the pan: Transfer the mixture to the prepared pan and firmly press it into an even layer.
Chill: Refrigerate for at least 30 minutes, or until firm.
Slice and serve: Lift the chilled mixture from the pan using the parchment paper and cut into 10 bars.

Notes

Storage

Store the bars in an airtight container in the refrigerator for up to 1 week. For longer storage, freeze them individually for up to 3 months and thaw before serving.

Recipe Tips

Use natural peanut butter that is well stirred for the best texture.
Add a little more milk if your protein powder makes the mixture too dry.
For extra crunch, add chopped peanuts or almonds.
For a chocolate version, mix in 1–2 tablespoons of unsweetened cocoa powder.
Press the mixture firmly into the pan so the bars hold together well.
