01 - In a medium bowl, whisk together the almond milk, chia seeds, maple syrup, and vanilla extract until evenly combined. Let the mixture rest for 10 minutes, then whisk again vigorously to break up any clumps that may have formed.
02 - Cover the bowl and refrigerate for at least 3 hours, or preferably overnight, until the mixture thickens 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 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.
05 - In a bowl, combine the gluten-free rolled oats, almond flour, melted coconut oil, maple syrup, and a pinch of salt. Mix until the texture becomes crumbly and evenly moistened. Spread the mixture in a thin layer across the prepared baking sheet.
06 - Bake for 12 to 15 minutes, stirring halfway through, until the crumble turns a deep golden brown. Remove from the oven and let it cool completely on the sheet.
07 - Layer the chilled chia pudding, macerated strawberries, and cooled crumble in serving glasses or jars. Repeat the layers as desired, finishing with a generous sprinkle of crumble on top.
08 - Serve immediately at room temperature, or return to the refrigerator and chill until ready to enjoy.
