Slice the pound cake into approximately 1-inch cubes
In a large zip-top bag mix sugar and spice.
Add oil and butter to a large pan over medium heat. Add half the pound cake cubes. Toast and brown the cubes on all sides.
Immediately toss into the sugar mixture and toss lightly to coat.
Gently remove to a tray while you cook the remaining cake.
Serve immediately. Or after cooled store in an airtight container. (I prefer them warm.)
