01 - Whisk together chia seeds, coconut milk, maple syrup, cocoa powder, vanilla extract, and salt in a medium bowl until fully combined. Let stand for 5 minutes, then whisk again to break up any clumps. Cover and refrigerate for at least 2 hours or overnight until thickened.
02 - Preheat oven to 350°F. Toss hazelnuts with maple syrup and sea salt on a baking sheet. Bake for 8–10 minutes, stirring once halfway through, until golden and fragrant. Let cool completely, then roughly chop.
03 - Combine coconut yogurt with shredded coconut in a separate bowl. Stir until evenly distributed.
04 - Layer chia pudding, coconut yogurt mixture, and hazelnut crunch in 4 glasses or jars. Repeat layers if desired for taller parfaits.
05 - Top each parfait with chocolate shavings, toasted coconut flakes, and extra chopped hazelnuts. Serve immediately or refrigerate for up to 2 hours before serving.
