01 - In a medium bowl, whisk together almond milk, Greek yogurt, chia seeds, maple syrup, vanilla extract, and salt until thoroughly combined. Cover the bowl and refrigerate for at least 3 hours or overnight. Stir once after 30 minutes to prevent the seeds from clumping together.
02 - Combine blackberries, maple syrup, and lemon juice in a small saucepan over medium heat. Cook for 8-10 minutes, stirring occasionally, until the berries break down and the mixture thickens slightly. Remove from heat and allow to cool to room temperature before assembling.
03 - Layer the chilled chia pudding, cooled blackberry compote, and granola in 4 glasses or jars, repeating layers as desired to fill the containers. Top each parfait with fresh blackberries and mint leaves for garnish.
04 - Serve immediately for the crispiest granola texture, or refrigerate for up to 2 hours if you prefer softer, melded layers. The parfaits are best enjoyed the same day they are assembled.
