Preheat the oven to 300 °. Line a rimmed baking sheet with parchment or a silpat mat.
In a medium bowl combine the maple syrup and the spices. Whisk to blend.
Add the pepitas and toss to coat. Spoon the pepitas out into a single layer on the prepared baking sheet.
Bake for 15 minutes, stirring occasionally, until the pepitas are glazed. Cool the pepitas slightly and then break apart into clusters, if necessary. Cool completely and store in an airtight container.
Store pepitas in an airtight container and consume within 3 days.
