Buying protein bars at the store can get really expensive. That’s why I created a delicious homemade peanut butter-flavored protein bar recipe for you!

You can use any protein powder you want, but I decided to use whey protein powder. Each chewy bar gives you 12 grams of protein and is made with oat flour, which provides a ton of fiber, as well. Keep them chilled in the refrigerator until you’re ready to snack on one after your workout!


Homemade Protein Bars


  • 1½ cups quick oats
  • ¾ cup whey protein powder (or other protein powder of your choice)
  • ½ cup crispy rice cereal
  • ¼ tsp. salt
  • ½ cup creamy peanut butter
  • ¼ cup honey or other sweetener of your choice
  • 1 tsp. vanilla extract
  • ¼ cup vanilla almond milk
  • 3 Tbsp semi-sweet chocolate chips


  1. Add the quick oats to a small Magic Bullet cup and blend until you get a fine oat flour. Transfer to a mixing bowl and add the rice cereal, protein powder, and salt.
  2. Mix the ingredients together with a spoon, then mix in the peanut butter, honey, vanilla, and almond milk until you get a crumbly dough mixture.
  3. Line an 8-inch x 8-inch baking dish with parchment paper and firmly press the dough into the pan until flat.
  4. Place in the refrigerator and then melt the chocolate chips in a microwave safe dish, no more than 45 seconds at a time in-between stirs.
  5. Transfer the chocolate to a plastic bag and cut a hole in the bottom corner (the width of the hole will determine the size of the drizzle! I like mine small!)
  6. Squeeze the bag over the bars, drizzling melted chocolate all over.
  7. Place in the freezer for 10 minutes, then lift the parchment paper onto a cutting board and cut 12 bars.
  8. Store in the refrigerator until ready to eat.
