01 - In a medium mixing bowl, vigorously whisk together the almond milk, chia seeds, maple syrup, and vanilla extract until the seeds are evenly distributed throughout the liquid.
02 - Let the mixture sit at room temperature for 10 minutes, then whisk thoroughly again to break up any clumps and ensure smooth texture before refrigerating.
03 - Cover the bowl tightly with plastic wrap or a lid and refrigerate for a minimum of 4 hours, or preferably overnight, until the mixture achieves a thick, pudding-like consistency.
04 - While the pudding chills, combine fresh or frozen raspberries with maple syrup in a small bowl and mash with a fork until the berries release their juices but retain some chunky texture. Refrigerate until serving time.
05 - Spoon a generous layer of the thickened chia pudding into the bottom of serving glasses or jars, followed by a layer of the raspberry mixture. Repeat the layering process until the containers are filled, ending with a decorative top layer.
06 - Finish each serving with fresh raspberries, a sprinkle of sliced almonds, and fresh mint leaves if desired. Serve immediately while thoroughly chilled for optimal texture and flavor.
