01 - In a mixing bowl, whisk together the almond milk, chia seeds, maple syrup, and vanilla extract until evenly combined. Let the mixture rest for 5 minutes, then whisk again to break up any clumps. Cover tightly and refrigerate for at least 2 hours, or overnight, until thick and gelatinous.
02 - Combine the sliced strawberries, lemon juice, and maple syrup in a small saucepan over medium heat. Cook for 6 to 8 minutes, stirring occasionally, until the strawberries break down and the juices reduce into a glossy, syrupy consistency. Remove from heat and let cool completely.
03 - Preheat the oven to 350°F. In a bowl, toss together the oats, chopped nuts, melted coconut oil, maple syrup, cinnamon, and salt until everything is well coated. Spread the mixture in an even layer on a parchment-lined baking sheet. Bake for 10 to 12 minutes, stirring once halfway through, until golden brown and crisp. Set aside to cool completely.
04 - Spoon a layer of chilled chia pudding into the bottom of each serving glass or jar. Add a generous spoonful of strawberry compote, then sprinkle with oat crumble. Repeat the layers once more for a taller parfait, finishing with the crumble on top. Garnish with thinly sliced fresh strawberries.
05 - Serve immediately for the best crunch, or cover and refrigerate for up to 2 hours before serving. If storing longer, keep the crumble separate and add just before eating to preserve its crisp texture.
