Frozen Blueberry Refrigerator Cake

Chop 1/2 cup frozen blueberries. Set aside.

Fold yogurt with the non-dairy cream. Add chopped blueberries.

In a 4-by-6-inch sheet of foil tin, layer graham crackers alternately with yogurt-berry mixture. Top with remaining blueberries.

Freeze for four hours or until ready to serve. Cut into squares.

Blueberry shopping tip:  To assure good-quality frozen blueberries, shake the bag and check if the blueberries move freely. Clumps mean the berries have been thawed and refrozen.
