Easy No Bake Protein Bars

Updated: Aug 20, 2020

Simple, easy, no bake protein bars that are melt-in-your-mouth delicious!

The best type of snack? One that can be used for enjoyment and fuel! These soft peanut butter, oat protein bars are exactly that. Whether you’re looking for an end of day treat or a midday pick me up, these will be sure to curb your craving.

Made with oatmeal, protein powder, honey, m&m’s, chocolate chips, and vanilla — These bars require zero baking and only 10 minutes of prep time.

I used this Pampered Chef Silicone Snack Bar Maker. This snack bar maker is one of my top 10 favorite items in my kitchen. I would recommend this thing to anyone, it’s so easy to use and clean. But, if you don’t have anything like this, I would recommend using an 8x8 glass baking pan (linked on here for you on Amazon) or making these into balls.

Top Tips for Making Oatmeal Protein Bars

  • These bars can be kept in the freezer for about a month

  • Try adding dried fruit, seeds and nuts

  • You can use flavored or unflavored protein powders

  • You can substitute the honey used for maple syrup


  • 1½ cups Old Fashioned Oatmeal

  • ½ cup Peanut Butter

  • ⅓ cup Honey (or maple syrup)

  • ¼ cup Mini M&M's

  • ¼ cup Mini Chocolate Chips

  • ¼ cup Flaxseed (optional)

  • ½ tsp Vanilla (optional)

  • 1 scoop :INFINIT Raw (24.8 g)


  1. Prepare your serving dish – You can use a silicone snack bar mold, 8x8 glass baking dish, or other airtight storage container. If you’re using a snack bar silicone mold, you do not need to spray it down with oil. If you’re using a glass baking pan or other storage container, line it with wax paper.

  2. In a medium bowl, combine all of the ingredients and stir until everything is well combined.

  3. Place the mixture into your bar mold, glass dish, or roll them into 1 ½ inch balls and set them on a silicone baking mat or wax paper.

  4. Store the leftovers in the fridge for two weeks or freezer for up to three months.
