What is Upside Down Cake?
Upside-down cake refers to the method of making the cake. The fruit topping (in this case, the rhubarb), is added to the bottom of a cake pan.
Then the cake mix is poured over the top and then cooked. For the final step, the cake is flipped out of the pan so that the hot and sweet fruit filling is on the top!
This is an extra moist cake with lots of rhubarb flavor.

RHUBARB: If picking rhubarb, twist the stalks off and be sure to discard the leaves. If buying these pinkish stalks at grocery stores or a farmer’s market, they should be crisp (not limp) and should snap easily. If rhubarb isn’t in season, then use frozen rhubarb.
CAKE: The cake mix for this recipe is a simple cake from scratch.
A little butter (unsalted & room temperature), sugar, all purpose flour, milk, and eggs are just a few of the easy-to-find ingredients. Not much time on your hands? Replace the homemade cake with a boxed cake mix.
VARIATIONS: Add some sliced strawberries to the rhubarb for a sweeter fruit topping. Add some lemon or orange zest.
