White cake mix and strawberry jello aren’t just fun ingredients – they also make this recipe so painless. You might even have a lot of these yummy components already in your fridge and pantry.

Although this dessert is filled with juicy ruby red deliciousness, the top layer actually has a soft crunchiness. The flavor of sweet strawberries blend perfectly with the taste of tart rhubarb. It really has everything you would ever want in a baked treat.

Using strawberry jello and cake mix, makes this dessert similar to a strawberry rhubarb dump cake – although it doesn’t have a “cake texture” in the true sense fo the word. It is a great mix between a dump cake, a rhubarb crisp and a strawberry rhubarb cobbler.

rhubarb stalks and leaves


Rhubarb is a great dark green leafy vegetable. It’s not citrus but it is sourer than a lemon or lime.  

As an ingredient in pies and jams, it has been the secret to success for centuries. However, you have to know a bit about using rhubarb if you aren’t familiar. Especially when cooking and baking with fresh rhubarb.

For starters, do not cook with the leaves. Toss them in your compost or trash. I know it seems like those dark green leaves would be fun to try in a salad, but they are super high in oxalic acid. 


Not poisonous, but oxalic acid is only good in very small amounts. Too much should be avoided.

Oxalic acid s known to be a root cause of kidney stones. You definitely don’t want to go down that road. So best to just remove the spine and dispose of the green leaves properly. The spine is safe to eat. The leaves definitely are not. 

Luckily, if you are planning on using canned or frozen rhubarb then no worries.


Rhubarb is definitely described as sour. Its tart flavor can feel citrusy, but it will make you pucker like if you were eating a tart green apple or green grape! That is why many people will pair them with strawberries, to bring out the sweetness in desserts.


Don’t let the leafy greens of the rhubarb plants scare you off. The stalks are fine. In fact, they are super high in lots of things you do need, like fiber, vitamin C, and many essential minerals, like manganese, potassium, calcium, and vitamin K.
