  • Preheat the oven to 375°F.
  • Spray a 9-inch or 8-inch circular or square baking dish with cooking spray. Add blueberries to the dish and drizzle vanilla over top. Set aside.

  • Once combined, spoon oatmeal pecan topping over the blueberries. Gently press the mixture down using the back of the spoon.

  • Bake in preheated oven for about 30 minutes, or until blueberries are bubbling and topping has hardened and turned a lovely golden brown color.

  • Cool for 10-20 minutes then serve with whipped topping or ice cream.



  • Blueberries – As I mentioned above I love using frozen wild blueberries for this recipe, but if you don't have any on hand no worries regular fresh or frozen blueberries will work.
  • Pecans – If you're not a fan of pecans you could try another chopped nut such as walnuts.
  • Thicker filling – The blueberries will release a little juice after cooking. I don't mind a little liquid and like to keep the filling super simple, but if you prefer a thicker filling you can combine the blueberries and vanilla with 2-3 Tablespoons of cornstarch or arrowroot powder before adding to the baking dish.
