Process the nuts for a minute, stopping to scrape them off the sides of the food processor. As you keep processing, the oils from the nuts will unfurl, providing the mixture with moisture.
Repeat this step (pause every minute to scrape the sides) while chucking in the add-ins: If it's on the liquid-y side, like honey or maple syrup, drizzle it in gradually to get the consistency you desire. It's hard to mess up your nut butter, but be extra conscious to not let the machine run for more than one minute at a time. warns that this will cause the machine to overheat. Once your spread meets your texture preference requirements, store in an airtight container.
