Peanut Butter Protein Bars

peanut butter protein bars

For all of my fitness buffs out there, you are going to be so stoked about this protein bar recipe! As you know, I have been hitting the gym pretty hard lately to get back into my pre-preggo shape (and hopefully better!). I am doing a lot of resistance and weight training to increase my muscle mass on the days I am not doing cardio, so it is important for me to get a lot of protein in my diet right now. These peanut butter protein bars no-bake, meaning no cooking is required! They are made from scratch, using whey protein powder. Each protein bar has 12 grams of protein. I used rolled oats and blended them into oat flour, then mixed it together with the whey protein powder, peanut butter, vanilla, almond milk, and honey. I drizzled some chocolate on top to make them extra sweet, but you can skip that of course! What can I say, I have a huge sweet tooth 😉

These whey protein bars are really easy to make at home, and they are a great post-workout snack to give you a boost of energy and allow your muscles to recover. Keep them in the refrigerator so they stay nice and firm!

Last Thursday I weighed in at 133, which means I lost 1 pound since the previous week (hooray!). As I posted before, it is a little confusing if I am gaining muscle or losing fat, and how that looks like with these weigh-ins…I am not taking the number too seriously, and just going off how I feel and making sure I stick to the work-out plans. Each time I do a work-out, I have been noticing it is getting easier and I am getting in better fitness shape. I have been really good about cutting out sweets lately, too! If you know me, you know that is a big challenge. It is really tough going from a “pregnancy diet” (donuts, pizza, ice cream…) to a more healthy diet consisting of mostly fruits and vegetables, but I am getting used to it again!

Hope you enjoy these peanut butter protein bars as much as I do!

Peanut Butter Protein Bars
Prep time
Type: Snack
Serves: 12
  • 1½ cups rolled oats
  • ½ cup rice cereal
  • ¾ cup whey protein powder
  • ¼ tsp salt
  • ½ cup creamy peanut butter
  • ¼ cup honey
  • 1 tsp vanilla extract
  • ¼ cup vanilla almond milk
  • ¼ cup semi-sweet chocolate chips
  1. Add oats to a blender and blend into a flour.
  2. Transfer the oat flour to a mixing bowl, and add the rice cereal, protein powder, and salt.
  3. Mix the ingredients well with a wooden spoon, then add the peanut butter, honey, vanilla, and almond milk. Stir until you get an evenly moist crumbly mixture.
  4. Line an 8-inch x 8-inch baking dish with parchment paper, and use another sheet of parchment paper to firmly press the dough into the pan.
  5. Place in the refrigerator.
  6. Melt the chocolate chips in a microwave safe dish, no more than 45 seconds at a time in-between stirs.
  7. 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).
  8. Squeeze the bag over the bars, drizzling melted chocolate all over.
  9. Place in the freezer for 10 minutes, then lift the parchment paper onto a cutting board and cut 12 bars.
  10. Store in the refrigerator.
Makes 12 bars
