These BIG protein cookie bars are just 159 calories and 7.4g or protein, and have 1 scoop of protein per cookie bar!

I used plant based protein powder in this protein cookie bars recipe, that helps make this recipe vegan (you'll also need to get vegan chocolate chips). But you can use your favorite protein powder… the amounts roughly 1.25 cups (1 1/4 cups) of protein powder.

Special Tip: You can swap out the vanilla protein powder for chocolate protein powder for double chocolate cookie bars.

Equipment

Parchment paper
9×9 baking dish

Ingredients

1 cup old fashioned oatmeal
½ cup almond, peanut, or cashew butter
10 scoops vanilla protein powder (based off 25g scoops)
¾ cup water (more as needed- see notes)
¼ cup dark chocolate chocolate chips

Instructions

Line an 9×9 baking dish with parchment paper (if you crumple it first then smooth out, it’s easier) and set aside.
In a food processor or high speed blender, add the oatmeal and blend until it's the consistency of flour.
To the oat flour, add nut butter, protein powder, and water and blend until smooth.
Fold in the chocolate chips until well distributed.
Transfer to the prepared baking dish and press down to evenly distribute.
Refrigerate for 2-3 hours until firm.
Remove the protein bars from the fridge, and cut into 10 bars.

Notes

Special Note: Each protein powder is a little different, and you may need more water. Add 1 tablespoon of water at a time until you reach your desired consistency.
