01 - In a mixing bowl, whisk together the almond milk, chia seeds, maple syrup or honey, and vanilla extract until fully 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 the pudding thickens to a creamy consistency.
02 - Combine the hulled and sliced strawberries, lemon juice, and maple syrup or honey in a small saucepan. Place over medium heat and cook for 6 to 8 minutes, stirring occasionally, until the strawberries break down and the liquid reduces to a glossy, syrupy consistency. Remove from heat and let cool completely.
03 - Preheat the oven to 350°F. In a bowl, toss together the rolled oats, chopped almonds or pecans, melted coconut oil, maple syrup or honey, ground cinnamon, and a pinch of 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 - In serving glasses or jars, spoon a layer of chia pudding into the bottom. Add a generous spoonful of strawberry compote, followed by a sprinkling of oat crumble. Repeat the layers for a second tier if desired, finishing with a few slices of fresh strawberry on top.
05 - Serve immediately for the best texture contrast, or cover and refrigerate until ready to enjoy. If storing ahead, keep the crumble separate and add just before serving to maintain its crunch.
