Equipment

Ingredients

  • 2¼ cup Blueberries fresh, washed. Reserve ¼ cup for topping.
  • 1 Lemon Cake mix 15.25 oz
  • 4 oz Butter melted

Optional Icing

  • ½ cup powdered sugar
  • 3 teaspoon lemon juice
US Customary - Metric

Instructions

  • Preheat the oven to 350 degrees F. Spray a 9x13 inch casserole or baking dish with non stick cooking spray.
  • Wash the fresh blueberries and then spread them out in the bottom of the baking dish in a single layer. Be sure to reserve ¼ cup of the blueberries for the topping.
    PRO TIP: Make sure to only make a single layer of blueberries. This will ensure the cake mix is more cookie texture for cake bars.
    2¼ cup Blueberries
  • Sprinkle the lemon cake mix evenly over the top of the blueberries.
    1 Lemon Cake mix
  • Melt the butter on the defrost option in the microwave (this melts it evenly without splattering) and drizzle over the top of the cake mix.
    4 oz Butter
  • Spread the reserved blueberries over the top of the butter topped cake mix.
  • Bake in the preheated oven for 40-45 minutes, or until golden brown and bubbly on top. Allow to cool for 20 minutes before cutting into bars and serving.

Optional Icing

  • Mix ½ cup powdered sugar with 2-3 tablespoons of lemon juice and drizzle on top of lemon bars.
    ½ cup powdered sugar, 3 teaspoon lemon juice

Notes

Here are a few tips for making these blueberry lemon cake bars :
  • Use fresh blueberries for the best flavor. If you don't have fresh blueberries, you can use frozen blueberries, but be sure to thaw them completely before using.
  • Let the cake cool slightly before serving. This will help the bars hold shape when cut.
  • Drizzle with powdered sugar icing after cooling for a delicious, final touch. Mix ½ cup powdered sugar with 2-3 tablespoons of lemon juice and drizzle on top of lemon bars.
