These healthy no bake peanut butter protein bars made with oatmeal contain only four simple ingredients, are packed full of protein and are super easy to prepare! Made in less than 15 minutes, these low sugar protein bars are the perfect healthy snack for on-the-go. Ditch the store-bought bars and make your own! {Gluten-free & vegan-friendly}
In a large bowl, mix together the oats and vanilla protein powder.
Next, add the peanut butter, almond milk, and maple syrup, if desired. Stir until well combined and slightly sticky. The mixture should bind together but not be gooey.
Line a 9-inch square baking pan with parchment paper and press the mixture into the pan with a spatula until equally distributed. Place the pan in the freezer for 30 minutes.
Remove from freezer and cut the mixture into 8 equal-sized bars using a sharp knife. You may need to allow mixture to thaw out for a few minutes before you can cut through the bars.
Place each bar in a little Ziploc bag or saran wrap and store in fridge or freezer.

Notes
Adjust milk as necessary: You may need to adjust how much almond milk you add based on the type of protein powder used. Generally, I find that vegan protein powders produce a thicker consistency and usually require slightly more liquid than a whey protein powder.
Wet the spatula with a bit of water before pressing down the mixture in the baking dish to prevent it from sticking to the spatula.
Experiment with add-ins: Feel free to play around with these bars and customize them with chocolate, dried fruit or other tasty add-ins (see below for some suggestions)!
To store: You can store these bars in the fridge for up to a week or in the freezer for up to three months.
