1. Add all the ingredients except for 1/4 cup of the nuts and 1/4 cup of the raisins to a glass bowl that will fit inside your slow cooker. Give it a good stir, and place the bowl in the center.
2. Carefully fill the slow cooker with water, to about 1 inch below the rim of the glass bowl. Cook on low for 8 hours.
3. In the morning, remove the lid and stir up the oatmeal. Scoop out about a 1-cup serving, and top with a sprinkling of nuts and raisins.
4. Store uneaten oatmeal in the fridge.
