This rhubarb dump cake recipe was given to me years ago by our favorite farm stand owner, Mrs. Taylor. I scribbled it in pencil on the back of a church bulletin that was in the car. Thirteen years later, that is still how it is filed in my recipes. Mrs. Taylor always insisted on giving a treat to my oldest children, whether it was a handful of berries, a new vegetable to try, or most commonly, an apple. One of them even called her “Apple” and drew pictures of apples to give to her. She helped them develop a lifelong love of fruits, vegetables, and trying new things–including rhubarb.
This rhubarb dump cake is a great way to introduce kids to rhubarb. It’s a simple recipe they can make with very little help, and it features cake mix and jello mix, two kid-friendly ingredients. Many rhubarb recipes call for a lot of rhubarb, so this recipe is great because you need only two cups of the sour fruit to make it. This Rhubarb Dump Cake isn’t the prettiest of cakes, but it is very tasty and quick to throw together.
Dairy-Free Cake Mix Options
If you opt to try a gluten-free yellow cake mix (we haven’t tested it yet), some dairy-free selections include Bob’s Red Mill, Cherrybrook Kitchen Gluten Free, and Hodgson Mill.
Since you are using the dry cake mix in this recipe (not prepared), you don’t need to worry about any dairy called for in the cake mix instructions.
