Step 1

In a small dry skillet over medium-high heat, toast the pecans, stirring frequently, until fragrant, 3 to 5 minutes. Transfer to a cutting board to cool, then coarsely chop. Set aside half of the pecans and transfer the remaining to an airtight container and refrigerate.

Step 2

In a medium bowl, whisk together the milk, yogurt, pumpkin puree, maple syrup, vanilla, cinnamon, cloves and ginger until combined. Stir in the reserved pecans and the oats. Taste, and add 1 more tablespoon of maple syrup, if desired. Let the mixture sit for 15 minutes, then stir well and divide the mixture evenly among four 12-ounce (1 1/2-cup) jars. Cover the jars tightly and refrigerate for at least 8 hours and preferably overnight.

Step 3

Right before serving, top each jar with a quarter of the refrigerated pecans, a dollop of yogurt and a sprinkle of cinnamon.
