Units Scale

For the bars:

For the chocolate topping:

  • 1/2 cup chocolate chips (dairy-free if necessary)
  • 2 tbsp cashew butter
  • 1 tbsp coconut oil
  • Sea salt, for topping bars


  1. Line an 8x8 inch square baking dish with parchment paper going both ways.
  2. Place oat flour, protein powder, salt, and baking soda in a large mixing bowl, stirring to combine.
  3. Add maple syrup, cashew butter, almond milk, and vanilla. Stir until you have a ball of "dough." Using wet hands, press evenly into prepared baking dish.
  4. Make chocolate coating by placing chocolate chips, coconut oil, and cashew butter in a medium microwave-safe bowl. Microwave in 20-second intervals for about a minute, or until melted, stirring each time. Pour chocolate over bars and use a spatula to spread evenly.
  5. Freeze for at least 2 hours before slicing into 9 bars. Top with a sprinkle of salt and devour!


*You can make your own oat flour by grinding old-fashioned oats in the Nutribullet or a high-speed blender.
