Grease or spray a 8 inch square pan with oil
Process (blend), oats, protein powder, and salt together into a fine crumb
Drain dates (reserve some of the water). Add dates to processor and blend until well combined. (I added to oat mixture and processed all together)
Transfer dough to a bowl and mix peanut butter through by hand. Dough should be like cookie dough so may need to add some of the date water.
Add to pan, pressing mixture into it. Spread out evenly using a large spatula and place in freezer while you prepare chocolate.
Melt chocolate in microwave in 30 second intervals (or can do over boiling water in a pan). When melted pour over the mixture in pan and spread evenly.
Spread nuts over top and refrigerate.
Once they have hardened, cut into 16 pieces.
Can store in refrigerator for a week or freezer for up to 3 months.
