These Blueberry Oatmeal Bars are so quick and easy to whip up! They start with your favorite butter cake mix and quick oats. Use whatever flavor preserves you love the most, but blueberry is my fave!
Serves: 24-28
  • 1 (18-1/4 ounce) package yellow butter cake mix
  • 2 1/2 cups quick-cooking oats
  • 3/4 cup butter, melted
  • 1 (12-ounce) jar seedless blueberry preserves
  • 1 tablespoon water
  • 1 heaping cup frozen blueberries
  1. Preheat the oven to 350 degrees F and spray a 9 x 13-inch pan with cooking spray. In a large bowl, mix together the cake mix, oats, and melted butter until the mixture is all moistened. Spoon about 3 cups of the mixture into the prepared pan and flatten it evenly over the entire bottom of the pan. Bake for 10 minutes and set on a cooling rack to cool while you mix the filling.
  2. Whisk together the blueberry preserves and water until well combined. Spoon this over your warm crust and spread evenly. Top with frozen blueberries spread all around. Then sprinkle the rest of your crumble mixture evenly over the top. Bake for 25-28 more minutes or until the crumble is lightly golden. Cool completely (I even chilled for an hour so the cuts would be nice and clean) and then serve!
