In large food processor, add the protein powder, and oats. Blend for 1 minute, until the oats are powdery, as pictured above.
Add the coconut flakes, chia seeds, lemon zest, lemon juice, melted coconut oil, almond butter, and honey to the food processor. Blend the mixture for another 30 seconds, or until mixture is well combined.
Check consistency by folding some of the mixture in your hand; it should form a ball and not crumble. If the mixture is crumbly, add water and process again.
Line a 9 x 5 inch loaf pan with parchment, and press the protein bar mixture into the pan until smooth across the top. Chen chill for 2 hours (or freeze for 30 minutes).
Optional drizzle: you can drizzle melted white chocolate and extra lemon zest over the top if desired.
