In a high-quality food processor, add your peanut butter, cocoa powder, and sweetener. If using salt, sprinkle it in too. Pulse for about 30 seconds until well combined and a sticky dough forms.

Continue blending for another 30 seconds to 1 minute, scraping down the sides as needed for a smooth consistency.

Stir in any optional ingredients like mini chocolate chips or chia seeds until evenly distributed throughout the mixture.

Shape the dough into balls or bars, about 1-inch in size, and place them on a parchment-lined tray.

Chill the bites for at least 30 minutes or store them for later. They can be kept at room temperature for a week or in the fridge for up to three weeks.
