Preheat the oven to 350°F (175°C) and line an 8x8-inch baking pan with parchment paper.
In a food processor, blend the Medjool dates until they form a sticky paste.
Transfer the date paste to a mixing bowl and stir in cashew butter, brewed coffee, and vanilla extract until smooth.
In another bowl, combine rolled oats, cocoa powder, chocolate protein powder, and salt. Mix well.
Combine wet and dry mixtures, stirring until everything is thoroughly combined. Fold in chopped cashews for that delightful crunch.
Spread the mixture evenly in the prepared baking pan, pressing down firmly to ensure a solid bar.
Bake for 20 minutes, or until the edges start to firm up.
Remove from the oven and allow to cool completely in the pan before slicing into bars.
