How to Make It

  1. Preheat oven to 350°F.
  2. Combine first 4 ingredients in a small saucepan; bring to a boil. Reduce heat to medium-low; cook 6 minutes or until thick, stirring frequently. Remove from heat; stir in rind and juice.
  3. Weigh or lightly spoon flour into a dry measuring cup; level with a knife. Place flour, oats, brown sugar, and salt in a food processor; pulse 2 times to combine. Add butter; pulse 5 times or until mixture resembles coarse meal. Combine oil and vanilla; drizzle over flour mixture. Pulse 4 times or until moist.
  4. Reserve 2/3 cup flour mixture. Pour remaining flour mixture into a parchment-lined 8-inch square light-colored metal baking pan coated with cooking spray; pat into an even layer in bottom of pan. Spread blueberry mixture on top all the way to edges. Sprinkle evenly with reserved 2/3 cup flour mixture. Bake at 350°F for 45 minutes or until topping is lightly browned and filling is bubbly and almost set on edges. Cool completely in pan on a wire rack. Cut into 16 bars.
