Ingredients
Oats
- 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
Crumble Topping
- 3 tablespoons all-purpose flour
- 1 tablespoon light brown sugar
- 1½ tablespoons unsalted butter, melted
- ½ teaspoon ground cinnamon
- ⅛ teaspoon salt
Instructions
- Prepare Berry Mixture: Combine frozen mixed berries, 2 teaspoons chia seeds, ¾ teaspoon brown sugar, lemon juice, ¼ teaspoon cinnamon, and salt in a medium saucepan. Cook over medium-low heat, stirring occasionally, until most berries burst, about 6 minutes. Remove from heat and cool to room temperature for 5 to 8 minutes. Transfer to a small bowl, cover, and refrigerate until ready to use.
- Mix Oats: In a medium bowl, stir together whole milk, rolled oats, yogurt, vanilla extract, remaining 1 tablespoon chia seeds, and 1 tablespoon brown sugar until fully combined. Cover and refrigerate for at least 8 hours or overnight.
- Make Crumble Topping: Preheat oven to 350°F (175°C). Line a small rimmed baking sheet with parchment paper. In a small bowl, combine flour, brown sugar, melted butter, cinnamon, and salt; mix until the mixture holds together when squeezed. Spread mixture evenly on the baking sheet.
- Bake Topping: Bake crumble topping until fragrant and lightly toasted, about 5 to 7 minutes. Remove from oven and let cool completely on the baking sheet, about 15 minutes. Transfer crumble topping to an airtight container and store at room temperature until ready to use.
- Assemble Oats: To serve, spoon about ½ cup oat mixture into each of 4 jars (12-ounce jars). Layer about 3 tablespoons of the berry mixture over the oats, then top with an additional ½ cup oat mixture in each jar.
- Add Crumble: Just before serving, sprinkle about 2 tablespoons of the crumble topping on top of each jar for a crunchy finish.
- Make Ahead Storage: Refrigerate berry mixture for up to 4 days, oat mixture for up to 4 days, and store crumble topping at room temperature for up to 5 days.
Notes
- You can vary the berry types with blueberries, raspberries, or strawberries as preferred.
- Use whole milk for creaminess; substitute with plant-based milk if dairy-free.
- Prepare crumble topping fresh or in advance to keep it crunchy.
- Refrigerate assembled oats for an additional 1-2 days if needed, but add crumble topping just before serving to maintain texture.
