Tips on Making Rhubarb Dump Cake

What makes this rhubarb dump cake recipe stand out is that we’re making the cake from scratch. Trust us, skipping the white cake or yellow cake mix elevates its taste even more. Ready? Here are some more tips you should know about making this easy dessert:

  • Use fresh ones that have plump and firm stalks. If rhubarb season is over, however, you can just opt for frozen rhubarb. We do not recommend using canned ones as those are too sweet.
  • Keep the butter cold. While most recipes suggest using melted butter and pouring it over the flour, using diced cold butter gives the cake a better texture. It’ll melt as it cooks. Also, take note that salted butter will give this dish a better flavor than unsalted butter.
  • Mix other fruits with the rhubarb. Its flavor blends well with cherries and berries, so feel free to make it a strawberry rhubarb dump cake.
  • Add texture by topping the cake with nuts. You can also mix the nuts in with the fruits.

Frequently Asked Questions

What is the difference between cobbler and dump cake?

You cook both fruit desserts with some type of pastry on top. The difference is that a cobbler is topped with either a batter or biscuit dough, while a dump cake is usually covered with a dry cake mix.

Why is my rhubarb dump cake dry?

The dump cake ends up dry when the ingredients have not been spread evenly. Stay away from this mishap by making sure to keep each layer of ingredients even. This will also ensure that you get an even taste of fruit and cake in every bite.
