Ingredients Method Notes

Ingredients
  

Base
  • 1.5 cups whole rolled oats
  • 1 cup creamy natural peanut butter no added sugar or oil
  • 0.25 cup ground flaxseed
  • 0.25 cup honey
  • 0.25 cup protein powder vanilla or unflavored, about 2 scoops
  • 1 tsp vanilla extract
Add-ins
  • 6 tbsp cacao nibs or mini chocolate chips
  • water optional, added 1 tsp at a time if mixture is too dry

Method
 

  1. Step 1: Mix the Base
    In a large bowl, combine oats, peanut butter, flaxseed, honey, protein powder, vanilla, and cacao nibs. Stir until thick and sticky.
  2. Step 2: Adjust the Texture
    If the mix is too dry, add water 1 tsp at a time, stirring after each addition until it holds together.
  3. Step 3: Shape into Balls
    Using a cookie scoop or hands, portion and roll into compact balls for travel durability.
  4. Step 4: Air-Dry for Travel
    Place on a tray and let sit uncovered at room temperature for 20 minutes to form a light crust.
  5. Step 5: Chill to Set
    Refrigerate for 1–2 hours until firm. Then pack in your chosen travel container.

Notes

Use parchment between balls to prevent sticking. For crunch, add almonds or seeds. Desiccated coconut on the outside keeps hands clean. Do a 'squish test' before travel. Store in airtight containers for up to 5 days without refrigeration.
Pro-tip: For travel in very hot weather, use Regular No-Stir Peanut Butter for better stability.
