Easy Rhubarb Dessert Recipe With Jello

Rhubarb Desserts are a summer favorite. This Easy Rhubarb Dessert recipe with Cherry Jello is absolutely delicious and perfect for a smaller crowd.

Rhubarb Dessert Recipe can be served hot with a scoop of ice cream or cooled and cut into rhubarb bars. Regardless of what you do, it’s going to be delicious!

My sister and I grew up next to a neighbor that grew a lot of rhubarb. We used to pick it and dare each other to eat it raw.

I am puckering up just thinking about it.

It was very difficult to take a bite and act like it was no big deal. I don’t think either one of us pulled that one off. I can’t think of anything that rivals the tartness of rhubarb.

I’ve heard a lot of people say they don’t like rhubarb. That’s just crazy talk in my opinion. If they’d just try this Cherry Rhubarb dessert, they’d change their mind.

When you sweeten and cook rhubarb such as in this easy rhubarb dessert recipe, it changes the flavor to a smooth sweet treat.

Another thing I love about this Cherry Rhubarb dessert is that it bakes in an 8×8 sized pan which is perfect for small get-togethers.

If you aren’t a cherry fan, strawberry jello is delicious too. The color it gives the fruit is amazing. Don’t you think?

What is rhubarb anyway?

I wasn’t sure and actually discovered it depends on where you live!

According to the Huff Post, “rhubarb is technically a vegetable but is legally considered a fruit.

In 1947 a New York court declared rhubarb a fruit because it’s most often cooked as one in the United States (and, it’s said because it was a way to save businesses who imported these stalks from spending additional money on taxes).”

Rhubarb is Poisonous! – Kind of…

That’s what my son told me. He’s an engineer and brilliant in my opinion but he doesn’t know his rhubarb facts. Here are a few rhubarb facts:

  • The leaves of the rhubarb plant are poisonous. However, the stalks are not and can be eaten raw.
  • Color has no effect on the flavor of rhubarb. It can be light green, pink, or red.
  • Rhubarb freezes well. You can freeze it in stalks or chopped up. There isn’t any need to cook or blanche it beforehand.

Rhubarb is HEALTHY! – TRUE

According to the Natural Food Series, “Rhubarb health benefits include treating Alzheimer’s, fighting cancerous cells, promoting circulation, supporting weight loss, strengthening bones, promoting digestion, combating cardiovascular diseases, regulating blood sugar levels, maintaining kidney health, preventing early aging, and a good source of antioxidants.”

I’ve got to start eating more rhubarb! I wonder if I can call this Rhubarb Cherry Dessert recipe a healthy food! Probably not.

You may need:

  • 8×8 pan – I baked my dessert in an antique pan and buttered the heck out of it. I have this non-stick version which would have worked great!
  • Whisks – I love my whisks and have them in several sizes, shapes, and colors. I have a gadget obsession I guess and love these!

You may want to stock up on rhubarb for these delicious recipes!

NOTE: I wouldn’t use frozen rhubarb for this Easy Rhubarb Dessert. It tends to absorb a lot of liquid and you don’t want it to bake up with too much liquid.

If you do try using frozen rhubarb, thaw completely and let excess liquid drain.

If you like this recipe, we would appreciate your comment and a 5-star ⭐️⭐️⭐️⭐️⭐️ review!

Definitely an easy recipe for sure. I never change a thing when I do a recipe for the first time. This is really good. I served with a little vanilla ice cream to cut the sweetness. It is a rhubarb recipe afterall. It will definitely be made again.

I omitted the egg in the crust and pre baked the crust 8 minutes. The rest of the recipe I made as directed for 40 minutes. It was fabulous! My family loved it. I will make it again. Thanks❤️

Great to know, Louella! I love it when I receive comments like this so readers know they can leave out the egg.

I haven't tried this yet but it sounds yummy. We do a lot of desserts with rhubarb for our clients for Meals. We have a lot of frozen rhubarb. Can we use frozen for this? Has anyone tried it with frozen? Can it be made in a sheet pan and would it have to be a double or triple recipe. I know everyone would love this.

Hi Josephine, great questions! I haven't used frozen rhubarb. If you do, thaw it on a paper towel to remove excess liquid. You can double this and put it in a 9x13 pan. I don't think a sheet pan would be deep enough so if you triple it use something like a large sheet cake pan. Let me know what you did and how it turned out! Thank you.

The rhubarb filling was tasty but the crust was so flat and leathery couldn’t even eat it. Too bad because I have a lot of rhubarb to use up. Disappointed

Perhaps you overworked the butter into the pastry or forgot the salt? I use this crust all the time and it's amazing!
