Ingredients

Instructions

  1. Step 1: Preheat oven to 375°F. Cut 2 cups rhubarb into 1/2-inch pieces and combine with 2 cups hulled strawberries in a 9x13-inch baking dish. Drizzle with 1 tbsp lemon juice.
  2. Step 2: In a bowl, mix 1/4 cup all-purpose flour, 1/2 cup rolled oats, 1/2 cup old-fashioned oats, 1/2 cup granulated sugar, and 1/2 tsp cinnamon. Add 4 tbsp cold butter and use a pastry cutter to blend until crumbly.
  3. Step 3: Sprinkle the oat mixture evenly over the fruit, pressing gently to form a compact layer.
  4. Step 4: Bake for 45-50 minutes until the topping is golden brown and the fruit is bubbling around the edges.
  5. Step 5: Cool for 20 minutes before serving with vanilla ice cream or whipped cream.
