- Pull up on the edges of the parchment paper to remove bars from the pan. Place on a large cutting board.
- Cut bars with a sharp chef knife into 24 squares
- ENJOY!

Cutting your Bars
Some things I have found to make these cut prettier:
Pull the pan from the freezer and allow them to warm up just slightly to prevent the chocolate from cracking.
If they are sticking to your knife, fill a tall glass with HOT water and dip your blade into the water to warm the blade. Dry the knife off before cutting.
Storing your dark chocolate peanut butter protein bars
After you cut the bars, you can wrap them individually in parchment paper squares or just stack them in a sealed glass dish. Store in the freezer for up to 3 months.

FAQ Dark Chocolate Peanut Butter Protein Bars
Do I need to make any adjustments based on what nut butter I use?
You want to find a nut butter that is just Nuts or Seeds. This recipe has honey and dark chocolate in it, so I do think it is too sweet if you use a peanut butter that is already sweetened.
Can I leave out the Flax Seed Meal
Of course! You may need to add a few extra tablespoons of protein powder to help thicken up your peanut butter mixture if you leave this out. This helps the dough have a firm texture and hold together. It also adds omega-3 fatty acids!
