White Chocolate Walnut Blueberry Bars 


  • 2-1/2 cups blueberries
  • 1/2 cup sugar
  • 1 tablespoon corn starch
  • 1 tablespoon water
  • 1 package Concord Blueberry Muffin Mix
  • 1/2 cup unsalted butter, melted
  • 1 large egg
  • 1/4 cup milk
  • 1/2 cup white chocolate chips
  • 3/4 cup walnuts, chopped
  • 3 tablespoons salted butter, melted 


  1. Preheat oven to 350 degrees. Grease a 9x9 pan. 
  2. Place blueberries and sugar in a medium saucepan over medium-low heat.  Mash blueberries lightly with the back of a wooden spoon while cooking.  Bring to a boil and cook 2-3 additional minutes allowing the blueberries to release their juices.  Remove from heat.
  3. In a small cup, stir together cornstarch and water until dissolved.  Stirring quickly and constantly, slowly pour cornstarch mixture into blueberries until combined. Continue stirring until thickened, 30-45 seconds.  Set aside. 
  4. Pour one cup of blueberry muffin mix in a small bowl, and set aside. 
  5. Place the remaining muffin mix in a medium mixing bowl, then stir in melted butter, egg, milk, and chocolate chips, until it comes together in a thick dough.  Scoop into greased pan and press down evenly with a spatula until level. 
  6. Pour blueberries on top of dough, spreading until evenly covered.  Add walnuts and salted butter to the small bowl containing the cup of muffin mix.  Stir with a fork until it comes together in coarse crumbles.  Sprinkle walnut mixture evenly on top of blueberries. 
  7. Bake 45-50 minutes, until top of bars are golden and bars are baked through. 
  8. Remove from oven and let cool to room temperature.  Place bars in refrigerator and chill 2-3 hours or overnight before slicing and serving.
