Beautiful Blueberry Cobbler

• 2 1/2 - 3 cups frozen blueberries (or fresh, but frozen work a bit better)
• 2/3 cup sugar
• 2 tablespoons cornstarch
• 3 tablespoons lemon juice
• 3 tablespoons water, plus 1/2 cup, divided
• 1 pinch salt
• 13 -16 ounces yellow cake mix (or two boxes of jiffy yellow cake mix)
• 1 egg
• 1/2 cup butter, plus
• 3 tablespoons butter, divided
• 2 teaspoons cinnamon sugar

1. Preheat oven to 350 degrees.
2. In a medium saucepan, mix sugar, salt and cornstarch until smooth. Add lemon juice and 3 tablespoon water, stir well. Stir in blueberries carefully. Bring to a boil over medium heat and cook, stirring constantly until sauce thickens, about 3 minutes. Be careful not to crush blueberries.
3. Melt a stick of butter and spread evenly in bottom of 9"x13" dish. Pour 1/2 of one box of dry Jiffy cake mix over butter. Pour blueberry mixture over dry cake mix. Mix the second box of Jiffy cake mix as directed (1 egg plus 1/2 cup water). Pour prepared cake mix over blueberry mixture. Use the last 3 tablespoons of butter to dot the surface of cake mix to help brown. Sprinkle cinnamon-sugar on top.
4. Bake 25-35 minutes, or until golden brown on top. Serve with whipped cream and/or ice cream.
