01 - Place walnuts, rolled oats, and cocoa powder in a food processor. Pulse until finely ground and well combined.
02 - Add pitted dates, honey or maple syrup, vanilla extract, and salt to the processor. Blend until the mixture holds together when pressed between fingers.
03 - Check the mixture texture. If too dry to hold together, add 1 to 2 teaspoons of water and blend again briefly.
04 - Scoop tablespoon-sized portions of the mixture. Roll each portion into smooth, uniform balls using clean hands.
05 - Roll each ball in your choice of mini chocolate chips, shredded coconut, or chopped nuts, pressing gently to adhere.
06 - Place brownie bites on a plate or baking sheet. Refrigerate for at least 15 minutes to firm up before serving.
