  • In a bowl or a stand mixer add all of the ingredients except chocolate chips. Mix by hand or with a mixer until a dough forms. The texture will be like a dense cookie dough.
  • Fold in chocolate chips
  • Press the mixture into an 8x4 pan lined with parchment paper.
  • Freeze for 1 hour so the bars can set. Cut into 8 even slices and serve. (Sprinkle with sea salt - optional)
  • Leftovers can be individually wrapped and stored in the fridge up to a week or freezer for 3 months.



Important Tip:  It's important to weigh out/measure your protein powder due to different densities of protein powders. I used Gold Standard Vanilla Whey Protein. It came out to about ½ cup , but measuring is strongly recommended. 
Gluten Free: To make gluten free make sure you use certified gluten free oats.
Maple Syrup: We have not tried replacing maple syrup with honey. I think it may work but can't be sure.
Peanut Butter- Do not use regular peanut butter such as Jif/Skippy. This needs to be a natural peanut butter with natural oils. We haven't tested cashew or almond butter but think it would work.
Vanilla Extract - You can omit vanilla extract from the recipe, it's not necessary but it does add a nice flavor.
Protein Powder- For best results, measure your protein powder with a scale. If you don’t have a scale just add about ½ cup a little at a time. Different proteins will create different flavor profiles,  nutrition info and texture. The protein used here was Gold Standard Vanilla Whey Protein. We haven't tested this recipe with vegan or other protein powders but it may work!
Oat Flour- Oat flour is simply old fashioned oats ground to a fine texture. If you don't have oat flour, grind your own old fashioned rolled oats with a food processor or blender until very fine. Purchased oat flour will often have a finer texture.
Flaxseed- For more protein, use 1/4 cup oat flour and 1/4 cup flaxseed meal.
Mini Chocolate Chips- Feel free to omit mini chocolate chips, or add more.
WW Freestyle Note: These are not a WW friendly recipe. You can save 2 points per serving by omitting chocolate chips. Points were calculated as follows: Maple Syrup: 12SP, Peanut Butter: 48 SP, Protein Powder: 5SP, Oat Flour: 8SP, Chocolate Chips: 12SP
