Mix together the syrup, peanut butter and vanilla in a food processor or stand mixer with flat paddle
In a large bowl, combine the protein powder, oats, cereal, flaxseed meal, and salt
Add the dry ingredients to the wet and blend together. It will be thick. Depending on your selected nut butter, you may need to add a small amount of olive oil, or peanut oil to the mixture
Fold or knead in the peanuts and chips by hand
Spread the dough between 2 pieces of parchment, and press/roll out into a sheet (I did this directly in my jelly-roll pan)
Place lower parchment with the rolled dough on a rimmed baking tray, and bake for 3 minutes at 300F
Remove, and score into bars, then return to oven for another minute to crisp edges
Allow to cool, then store in a covered container, or freeze in individual packages
Notes
The ingredients in this recipe have been lab-tested and a single serving should be low-FODMAP, using FODMAP data at time of posting
I used Nutribiotic Vanilla Flavored Brown Rice Protein Powder; depending on your choice, it could impact the protein content as well as flavor of the energy bars
The flax seed meal helps the bars hold together, and adds healthy fats and nutrients. Make sure your flax seed is fresh, otherwise it may have a strong flavor in the bars
