Preheat oven to 350 degrees F.
Place oats in a smaller bowl, boil the water or juice, and pour it over the oats. Let stand while you cream together the margarine or butter with the sugars.
Beat the eggs in one at a time, then stir in flavorings. Dump in the flour, salt, soda, and spices, and beat vigorously until smooth.
Oats now should look like oatmeal. Add it into the main batter and stir it around. At the end, mix in the chopped trail mix. By now, the batter should look thick and busy.
Using a Bundt pan or a spring-form pan, pour in batter until it fills the bottom two inches. The cake will take from 35-45 minutes to bake. Start checking it after 30 minutes. If the cake pulls away from the pan sides and/or if a knife or stout toothpick inserted in the middle comes out clean, this concoction is done!
