Combine flour, ¾ cup sugar, baking powder, salt, and cinnamon.
Combine eggs, milk, and oil.
Stir the above into the dry ingredients until moistened.
Spread the batter evenly over bottom of greased slow cooker. I use a cube of butter to grease my crockpot rather than a spray.
In saucepan combine berries, water and ¾ cup sugar.
Bring to a boil and then remove from heat.
Pour hot berry mixture over batter in crockpot.
Cook on high for 2 hours or until toothpick inserted in batter comes out clean. Turn off cooker and allow to set for 30 minutes before serving.
This would have been delicious with vanilla ice cream but in lieu of that I used some Cool Whip and nobody complained. ;)
