Heat a frying pan, add oats, and dry roast them on medium heat for 5-7 minutes.
Remove from the pan and set aside to cool.
In the same pan, add walnuts and dry roast on medium heat for 4-5 minutes.
Remove from the pan and set aside to cool.
Once oats and walnuts are cooled, add them into a food processor attached with an S-shaped blade.
Grind the oats and walnuts until they are coarsely ground.
If you like smooth energy balls without crunch, grind the oats and nuts until they turn into almost like a powder consistency.
Add dates, cocoa powder, maple syrup, hemp hearts, and sea salt.
Process until everything is well combined, stick together, and becomes almost like a dough.
If it is not coming together or is a little dry, add one or two tablespoon of water.
Scoop the dough with your hand, a tablespoon or a small ice cream scoop, and form it into small balls using your hands.
If it is too sticky and hard to form balls, lightly grease your palm with coconut oil or any other neutral oil.
Roll each ball into crushed walnuts (optional) for extra crunch.
Enjoy the oat and nut energy balls right away or store them into an airtight container and place them in the fridge for up to two weeks and in the freezer for up to a month.
