GF cake mix, cream cheese, butter, blueberries and lemon make for a delicious dessert or coffee cake.
Preheat oven to 350 degrees and grease 9x13 pan.
For bottom layer: combine cake mix, melted butter, eggs and lemon juice. Mix well and press into bottom of pan.
For top layer: mix cream cheese, eggs, powdered sugar and lemon zest until smooth. Gently fold in blueberries. Pour on top of the bottom layer.
Bake 35 to 45 minutes until middle of cake doesn't jiggle. The toothpick test won't work because it's gooey inside. Yum!
Sprinkle with additional powdered sugar, if desired, and allow to cool before eating.
Cake may be stored in the refrigerator for up to a week.
