Add all the whole ingredients to a spice mill or a Nutribullet with a milling blade. Blend all until finely ground.
Add the powder ingredients and pulse, and shake a few times until all gets mixed.
Add the blend to a jar, close well, and store in a dark and cool place for a few months.
If you don't have access to Tonka beans, don't worry, the blend will be amazing anyway. You can replace the flavor profile with vanilla or a mix of vanilla and nutmeg.
