Place the walnuts and almonds on a sheet pan and bake them on the bottom rack of the oven for 8-10 minutes or until they are slightly toasted and just starting to turn darker in color.
Let the nuts cool for 20 minutes then add to a food processor or high speed blender along with the maple syrup and salt.
Process until smooth and creamy.
Transfer to a jar or other covered container and store in the refrigerator.
