You can make this blueberry jam any time of the year with frozen blueberries. This is especially nice if you are unable to grow blueberries in your area or get them in bulk.
Use fresh or frozen blueberries and a box of lemon cake mix to make lemon blueberry dump cake! It tastes just like a homemade cobbler. No mixing or additional bowls needed for this dump cake with blueberries. #dumpcake #blueberrydumpcake
