Dump cake frequently asked questions, answers and tips:

Does this cake need to be refrigerated?

Once the cake has been cooled, store it in the refrigerator covered with plastic wrap or foil.

How to reheat this cake.

I scoop a portion into a microwave safe bowl and microwave on high for 2 minute. Be careful for hot spots in the cake.

Cake mix tips:

Sprinkle the cake mix over the sugared rhubarb and do not press it down. By pressing it you can form a crust and not allow the cake mix to fully hydrate leaving dry cake mix on the surface.

    Simply delicious! I followed the directions, but used yellow cake mix. It needed 20 mins uncovered in oven and it had a beautiful crust. It was difficult to wait till it cooled to eat it, we managed somehow. Very yummy and will be making it again.
