Add the peanuts, cocoa powder and monk fruit sweetener to a dry 1 litre mixer jar. Use the multipurpose or dry grinding jar, not the wet jar.

Grind once to break everything down.

Split the mixture into 2 batches. Add a pinch of salt to each.

Blend each batch in 1 minute intervals on coarse mode. Open the jar and scrape down the sides in between.

Keep going until it turns creamy and glossy. Mine took about 6 minutes.

Transfer to a clean, dry glass jar.
