In a large bowl, place in all ingredients (except milk) and stir together.
Add in milk and stir or combine with hands. You might need to add more milk to get a cookie dough texture.
TIP: If you have a stand mixer, throw everything in and use the dough hook attachment to combine it together. This will save your arms from getting tired.
Press mixture firmly into a 9x13 pan using a sheet of plastic wrap over top to avoid the mixture from sticking to your hands.
Place in the fridge for 30 minutes to firm them up. They will become less sticky once they are cold. Cut into bars.
If you like, you can take each bar out and place in a small plastic bag and store in the freezer or fridge for grab-and-go. Bars can also be stored in the fridge and consumed in about a week.
Notes
If you don't have peanut protein, you can substitute for whey protein (any flavor). You might need to use less milk. Start at ¾ cup and go up from there if needed.
