01 - In a mixing bowl, whisk together the almond milk, chia seeds, maple syrup, and vanilla extract until well combined. Allow the mixture to rest for 5 minutes, then whisk vigorously a second time to break up any clumps. Cover tightly and refrigerate for at least 2 hours or overnight until the pudding reaches a thick, gelatinous consistency.
02 - Combine the sliced strawberries, lemon juice, and maple syrup in a small saucepan set over medium heat. Cook for 6 to 8 minutes, stirring occasionally, until the strawberries break down and the juices reduce into a glossy, syrupy sauce. Remove from heat and let cool completely to room temperature.
03 - Preheat the oven to 350°F. In a bowl, toss together the rolled oats, chopped nuts, melted coconut oil, maple syrup, cinnamon, and salt until evenly coated. Spread the mixture in a thin, even layer on a parchment-lined baking sheet. Bake for 10 to 12 minutes, stirring halfway through, until the crumble turns 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 over the pudding, then sprinkle with oat crumble. Repeat the layers once more for a taller presentation if desired. Finish with fresh strawberry slices on top.
05 - Serve immediately for the best texture contrast, or cover and refrigerate the assembled parfaits for up to 2 hours before serving. For optimal crunch, add the oat crumble just before serving if storing in advance.
