  • Crust and Crumble Topping
  • 1/2 cup 1 stick unsalted butter
  • 1 cup all-purpose flour
  • 3/4 cup old-fashioned whole-rolled oats NOT instant
  • 1/2 cup granulated sugar
  • 1/4 cup light brown sugar packed
  • 1/4 cup Toasted coconut optional
  • Pinch salt
  • Blueberry Layer
  • 12 ounces 2 cups blueberries (fresh or frozen; I used fresh)
  • 1/4 cup granulated sugar
  • 2 tablespoons lemon juice
  • 1 tablespoon all-purpose flour


  • Preheat oven to 350F. Spray an 8x8 baking dish with cooking spray; set aside.
  • In a large, microwave-safe bowl melt the butter for 1 minute.
  • Add the flour, oats, sugars, optional salt, and stir to combine. Mixture will be dry and sandy with some larger, well-formed crumble pieces. This makes up the crust and crumble.
  • Set 1 heaping cup of the mixture aside to be sprinkled on later as crumble topping.
  • Transfer remaining mixture to prepared pan, and using a spatula or your fingers, hard-pack the mixture to create an even, smooth, flat crust; set aside.
  • In a large mixing bowl, add all ingredients for the blueberry layer and combine.
  • Distribute the blueberry mixture over the crust and sprinkle with the remaining crumble topping mixture.
  • Bake for about 55 minutes, or until the crumble is golden and the blueberry center is set. Be sure to watch the bars as they cook because the juiciness and fresh/frozen blueberries will add or reduce cook time.
  • Allow bars to cool completely before slicing and serving. Rushing this will result in messy and broken bars. Bars will keep for up to 1 week or refrigerated for 10 days.
