Ingredients

Scale
  • 1 cup old-fashioned rolled oats (90g)
  • 1 cup milk of choice (240ml), unsweetened almond or oat milk preferred
  • ½ cup plain Greek yogurt or cottage cheese (120g)
  • 2 tablespoons honey or maple syrup (30ml)
  • 1 teaspoon vanilla extract (5ml)
  • ¾ cup fresh or frozen blueberries (110g)
  • ½ teaspoon ground cinnamon
  • Pinch of salt
  • ¼ cup rolled oats (22g) for streusel topping
  • 2 tablespoons brown sugar (25g)
  • 2 tablespoons unsalted butter, softened (28g)
  • 2 tablespoons all-purpose flour (15g)
  • ¼ teaspoon ground cinnamon for streusel
  • Pinch of salt for streusel

Instructions

  1. In a large bowl, whisk together 1 cup (240ml) of milk, ½ cup (120g) of Greek yogurt or cottage cheese, 2 tablespoons (30ml) of honey or maple syrup, and 1 teaspoon (5ml) of vanilla extract until smooth.
  2. Stir in 1 cup (90g) rolled oats, ½ teaspoon ground cinnamon, and a pinch of salt until all oats are coated.
  3. Gently fold ¾ cup (110g) fresh or frozen blueberries into the oat mixture.
  4. Transfer the mixture into airtight jars or containers, cover tightly, and refrigerate for at least 6 hours or overnight.
  5. Preheat oven to 350°F (175°C). In a small bowl, combine ¼ cup (22g) rolled oats, 2 tablespoons (25g) brown sugar, 2 tablespoons (28g) softened unsalted butter, 2 tablespoons (15g) all-purpose flour, ¼ teaspoon ground cinnamon, and a pinch of salt. Mix until crumbly and spread evenly on a baking sheet.
  6. Bake streusel topping for 10-12 minutes or until golden brown and crisp, stirring halfway through. Let cool completely.
  7. When ready to serve, scoop the overnight oats into bowls or jars and sprinkle the streusel topping generously on top.

Notes

Use old-fashioned rolled oats for best texture. For dairy-free, substitute Greek yogurt or cottage cheese with coconut or almond yogurt and use plant-based milk and butter. Store streusel topping separately to maintain crunch. Re-toast streusel in a dry pan or oven if needed. Frozen blueberries can be used without thawing. Adjust sweetness based on blueberry ripeness.
