01 - In a medium bowl, whisk together the almond milk, chia seeds, maple syrup, and vanilla extract. Let the mixture rest for 10 minutes, then whisk again vigorously to break up any clumps that have begun to form.
02 - Cover the bowl tightly and refrigerate for at least 3 hours, or preferably overnight, until the mixture has thickened to a rich, pudding-like consistency.
03 - Combine the diced strawberries, lemon juice, and sugar or maple syrup in a bowl. Toss gently to coat evenly and set aside to macerate while you prepare the crumble topping.
04 - Preheat the oven to 350°F. Line a small baking sheet with parchment paper and set aside.
05 - In a bowl, combine the gluten-free oats, almond flour, melted coconut oil, maple syrup, and salt. Mix until the mixture resembles coarse crumbs. Spread evenly across the prepared baking sheet and bake for 12 to 15 minutes, stirring halfway through, until the crumble is golden brown and fragrant. Allow to cool completely.
06 - Spoon a layer of chia pudding into the bottom of each serving glass or jar. Add a generous spoonful of macerated strawberries, then sprinkle with crumble topping. Repeat the layers once more, finishing with a final dusting of crumble on top.
07 - Serve immediately at room temperature, or cover and refrigerate until ready to enjoy. The assembled parfaits hold well for up to 24 hours in the refrigerator.
