I couldn’t not add a chocolate topping, but we’ll get to that in a sec.

Peanut butter is making up the base of these homemade protein bars today, which means these are definitely going to be a crowd-please. I used a 100% pure peanut butter, nothing added. Mine was pretty drippy, so if you’re going that route give it a good stir before adding in the honey and coconut oil.

What You Need

  • peanut butter
  • honey
  • coconut oil
  • rolled oats
  • hemp hearts
  • chia seeds
  • protein powder
Ingredients for Peanut Butter Oat Bars

How to make Peanut Butter Oat Protein Bars

  • The peanut butter, honey and coconut oil go in the microwave to melt together.
  • Add your peanut butter mixture to your dry ingredients.
  • Then press the mixture into a lined pan.
  • Put in fridge to set.

These bars are SO EASY and take about 5 minutes to throw together.

Of course after the bars set, I decided I definitely needed some kind of topping. Naturally chocolate came to mind. But then I thought, “What if I added MORE peanut butter?…. HOLLA.” And so a peanut butter chocolate drizzle was born. You could do this a couple different ways, realistically. But what I did was melt 3 TBS mini chocolate chips + 2 tsp coconut oil, then stirred in 3 tablespoons of peanut flour until it was smooth. Then we DRIZZLE.

The peanut butter chocolate topping is just another way to sneak even more buttah into these bars Peanut Butter Protein Oat Bars. It might not be 100% necessary, but it sure is tasty.

Peanut Butter Protein Oat Bars

Making your own protein snack bars couldn’t be any easier with this recipe! These quick, no-bake Peanut Butter Protein Oat Bars are made with oats, peanut butter, and some protein powder for an extra filling snack with 10 grams of protein in each bar. Gluten-free friendly!

  • Prep Time: 5 minutes
  • Total Time: 45 minutes (includes chill time)
  • Yield: 12 bars 1x
  • Scale:
Print
Pin
Rate

Ingredients

for the bars:

  • 2 cups old-fashioned rolled oats (gluten-free if needed)
  • 3 TBS hemp hearts or flaxseed meal (can omit)
  • 2 TBS chia seeds
  • Scant 1/2 cup organic protein powder*
  • ¾ cup all natural peanut butter*
  • 1.5 TBS coconut oil
  • ⅓ cup + 1 TBS raw honey (or brown rice syrup)

optional peanut butter chocolate topping:

  • 3 TBS peanut flour
  • 2 TBS mini semi-sweet chocolate chips
  • 1 tsp coconut oil

Instructions

  1. Line 8×8 pan with parchment paper, set aside.
  2. In a large bowl, stir together dry ingredients (oats through protein powder). Set aside.
  3. In a medium microwave safe bowl, add peanut butter, coconut oil, and honey. Microwave for 10-15 seconds, and stir until evenly combined. Add this to dry ingredients, stir gently until mixture is evenly combined. Mixture will be thick and heavy.
  4. Press mixture into prepared pan, using hands to press evenly into all corners. Place pan in refrigerator for about 45 minutes to set (or 20 minutes in freezer).
  5. Once bars have set, lift parchment paper from pan and place on cutting board. Using a large sharp knife, cut bars into 12 servings.
  6. If using topping, melt chocolate chips and coconut oil in microwave for 10 second intervals. Once completely melted stir in peanut flour until no lumps are present. Drizzle peanut butter chocolate on bars and allow to set, about 15 minutes at room temperature.
  7. Store Peanut Butter Protein Oat Bars in airtight container in fridge up to 2 weeks, or in store in freezer for longer period of time. Enjoy!

Recipes Notes:

*I used Tera’s Whey Vanilla protein, and 1 serving=2 scoops. 3 scoops comes out to be a little less than 1/2 cup for this brand.

If using plant protein, you may need to add 1-2 TBSP milk to help bring the mixture together so it isn’t as dry – plant protein will absorb the dry ingredients differently compared to whey. 

*For the peanut butter I used a “drippy” kind with no added ingredients
