Spread the cherry pie filling across the bottom of the greased crockpot and sprinkle the chocolate chips over it.

Whisk together the flour, sugar, milk, melted butter, baking powder, and vanilla into a batter.

Spoon the batter evenly over the cherries.

Cover and cook on high for 3 hours, until the topping is set and cooked through.

Scoop warm with plenty of cherry-chocolate layer from underneath.
