These easy, no-bake protein balls combine creamy peanut butter, oats, and chocolate candies for a nostalgic, chewy snack that’s packed with protein and perfect for lunchboxes, parties, or post-workout fuel. With just five simple ingredients, they come together in minutes and are endlessly customizable for dietary needs.

Ingredients

Scale
  • 1 cup creamy peanut butter (unsweetened preferred)
  • 1 cup old-fashioned rolled oats
  • 1/2 cup vanilla protein powder
  • 1/3 cup mini chocolate candies (such as M&M’s minis)
  • 1/3 cup honey or maple syrup

Instructions

  1. Measure out all ingredients and set within arm’s reach.
  2. In a large mixing bowl, combine peanut butter and honey (or maple syrup). Stir until smooth and fully blended, about 1-2 minutes. Microwave peanut butter for 10-15 seconds if stiff.
  3. Add rolled oats and vanilla protein powder to the bowl. Mix gently with a spatula until well incorporated; dough will be thick and slightly crumbly.
  4. Fold in mini chocolate candies (and any optional extras like mini chocolate chips or chopped nuts). If the mix feels dry, add a teaspoon more honey or a splash of milk.
  5. Check consistency: dough should be firm enough to roll into balls but not dry. Add more oats if too sticky, or more honey if too crumbly.
  6. Use a cookie scoop or tablespoon to portion out dough. Roll between palms to form balls about 1 inch in diameter. Place on a parchment-lined plate or baking sheet. Yields about 16 balls.
  7. Refrigerate for 20-30 minutes to firm up. Balls can be eaten immediately, but chilling improves texture.
  8. Transfer set protein balls to an airtight container. Store in the refrigerator for up to 1 week or freeze for up to 2 months.

Notes

Use room temperature ingredients for easier mixing. Adjust honey or oats for desired consistency. For vegan, use maple syrup and plant-based protein powder; for gluten-free, use certified gluten-free oats. Lightly grease hands before rolling to prevent sticking. Chilling improves texture and helps balls hold their shape. Customize with mix-ins like mini chocolate chips, chopped nuts, dried fruit, or sprinkles.
