You can use any mixture of berries or stick to your favorite—whether it’s juicy blueberries, tart raspberries, sweet strawberries or a blend of all three.

Ingredients

1½ cups frozen mixed berries
2 teaspoons chia seeds plus 1 tablespoon, divided
¾ teaspoon light brown sugar plus 1 tablespoon, divided
2 teaspoons lemon juice
1½ teaspoons ground cinnamon, divided
¼ teaspoon salt
2¼ cups whole milk
2 cups old-fashioned rolled oats
½ cup reduced-fat plain strained (greek-style) yogurt
1 teaspoon vanilla extract
3 tablespoons all-purpose flour
1 tablespoon light brown sugar
1½ tablespoons unsalted butter, melted
½ teaspoon ground cinnamon
⅛ teaspoon salt

Directions

Prepare oats: Combine 1½ cups frozen berries, 2 teaspoons chia seeds, ¾ teaspoon brown sugar, 2 teaspoons lemon juice and ¼ teaspoon each cinnamon and salt in a medium saucepan. Cook over medium-low heat, stirring occasionally, until most of the berries have burst, about 6 minutes. Set aside to cool to room temperature, 5 to 8 minutes. Transfer to a small bowl; refrigerate, covered, until ready to use.
Stir 2¼ cups milk, 2 cups oats, ½ cup yogurt, 1 teaspoon vanilla and the remaining 1 tablespoon each chia seeds and brown sugar together in a medium bowl until fully combined. Cover and refrigerate for at least 8 hours.
Prepare crumble topping: Preheat oven to 350°F. Line a small rimmed baking sheet with parchment paper. Combine 3 tablespoons all-purpose flour, 1 tablespoon brown sugar, 1½ tablespoons melted butter, ½ teaspoon cinnamon and ⅛ teaspoon salt in a small bowl; stir until the mixture holds its shape when squeezed together. Spread evenly on the prepared baking sheet.
Bake until fragrant and lightly toasted, 5 to 7 minutes. Let cool completely on the baking sheet, about 15 minutes. Transfer to an airtight container and store at room temperature until ready to use.
To assemble, spoon about ½ cup oat mixture into each of 4 (12-ounce) jars with lids; arrange about 3 tablespoons berry mixture over the oats in each jar. Top each with an additional ½ cup oats. Sprinkle each jar with about 2 tablespoons crumble topping just before serving.
