Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F (190°C). In a medium bowl, gently toss 1 1/2 cups blueberries, 1 cup raspberries, 3 tbsp sugar, and 2 tbsp flour until berries are evenly coated.
  2. Step 2: Transfer berry mixture to a 8x8-inch baking dish, spreading evenly. In a separate small bowl, mix 1/2 cup rolled oats, 1/4 cup old-fashioned oats, 1/2 tsp ground cinnamon, and 1/2 tsp vanilla extract.
  3. Step 3: Melt 3 tbsp unsalted butter in a small saucepan over medium heat until golden and nutty-smelling (about 2 minutes), then pour over the oat mixture, stirring until all ingredients are moistened and clumpy.
  4. Step 4: Sprinkle the oat mixture evenly over the berries, pressing gently to adhere. Bake for 35-40 minutes until the topping is golden brown and the fruit is bubbling around the edges.
