Homemade Protein Bars

Prep Time 1 hour
Total Time 1 hour
Course Snack
Servings 16


  • 5 Medjool dates pitted
  • 1 cup all-natural drippy peanut butter
  • 1.5 cups ground oat flour
  • 1/3 cup honey
  • 1 teaspoon vanilla extract
  • 1/2 cup vanilla whey protein powder
  • Pinch of salt
  • 1/4 cup water adjust as needed

**Optional Topping:**

  • 3/4 cup dark chocolate chips
  • 2 teaspoons coconut oil
  • Coarse sea salt to taste


  • Start by lining a 9×9-inch or 9×13-inch baking dish with parchment paper. Any size works, but smaller dishes mean thicker bars.
  • In a high-speed food processor, combine dates, peanut butter, oat flour, honey, vanilla extract, and protein powder. Process until smooth, adding water as needed until you get a cookie dough-like consistency.
  • Transfer the dough into the prepared baking dish and press it evenly.
  • For the chocolate topping, melt dark chocolate chips and coconut oil together, then pour over the bars. Sprinkle with coarse sea salt.
  • Freeze the bars for 30 minutes to an hour until the chocolate sets.
  • Once set, slice and store in the fridge for up to 7 days or freeze for up to 3 months.


  • Ensure your Medjool dates are soft for easy blending.
  • Opt for drippy peanut butter for best results.
  • A high-speed food processor ensures a smooth consistency.
  • Use any size pan you have on hand.
  • Adjust water or oat flour to achieve the right consistency: more for dry, less for wet.
