Combine almond milk, oats, pumpkin, maple syrup, flaxmeal (or chia seeds), dates, espresso powder, pumpkin pie spice, vanilla and salt in a blender; process until smooth, about 30 seconds.
Divide the mixture evenly among 4 (8-oz.) jars. Cover and refrigerate until thickened, about 8 hours. Just before serving, top with yogurt and sprinkle with pumpkin pie spice.
