This easy, No Bake Rhubarb Dessert with a graham cracker crust, layers of rhubarb filling, vanilla pudding, and whipped cream, and marshmallows is the perfect way to enjoy your rhubarb crop this year! The flavors meld so perfectly together, with the sweet pudding and whipped cream marshmallows balancing the tangy rhubarb!
This recipe is especially popular during rhubarb season, which is generally the end of April (in many areas) until the end of June. This recipe is similar to my Cherry Cha Cha recipe on this site, and pairs well with any spring or summer meal, such as my shortcut skillet fried chicken and Healthy Potato Salad. This is like a dessert you'd have at an old-fashioned country picnic, making it an ideal summer potluck dessert. It can also be made dairy-free!
Whether you grow your own rhubarb, or get it at the farmers market or grocery store, rhubarb season is short, so dig in and make the most of it! Don't just make a rhubarb crisp recipe, get creative! If you're looking for unusual rhubarb recipes, you'll love this layered rhubarb dessert and my Sticky Rhubarb Pudding.

Hint: When you are spreading the layers on top of one another, be patient. Spread a little bit at a time (as you would frosting) so you don't everything smeared together. Your dessert will look nicer that way!
📖Variations & Substitutions
- Whipping cream - real whipping cream is ideal, but you can use Cool whip or another type of whipped topping as a substitute (keep in mind that it will be sweeter)
- Rhubarb - you can use fresh rhubarb or frozen OR use an already prepared rhubarb compote for this recipe
- Graham cracker crumbs-if you don't have crumbs, crush up graham crackers (you can do this in a food processer or by adding crackers to a large Ziplock bag and using a rolling pin to crush them)
- Vanilla Pudding-you can use a box instant pudding or a prepared instant pudding (i.e. snack packs) If you use the prepared snack packs * You'll need 4 -158 g -containers instant vanilla pudding snacks
- Dairy-free - use a vegan butter or margarine (Becel has one), use non-dairy milk in the Jell-0 instant pudding (it's naturally vegan) and use a non-dairy whipped topping

👪 Serving Size
This rhubarb recipe makes 12 servings. However, you can half, double, or triple the recipe by clicking on the blue serving number and selecting the number of servings you'd like. The ingredient quantities will automatically adjust. You will just need an additional 9X13 pan.
You don't need a food processor for this recipe because the rhubarb filling breaks down as it cooks. But you'll need a hand mixer and a 9X13 baking dish for this rhubarb dessert. I like to use a glass baking dish with a lid. The glass allows you to see the layers, which looks appealing and you can throw the lid on for storing in the fridge or transport! *See recipe card for equipment recommendation links and photos
Store this dessert with rhubarb for up to 4 days in the fridge in an airtight container. These ingredients don't stand up well to freezing.
Add a little red food coloring if your rhubarb looks a little brown. I use Americolor Super Red (affiliate link) so I only have to add a very small amount. If you use too much red food coloring, it produces a funny 'red taste'.
So if you're looking for a great way to use up lots of rhubarb in an easy recipe, or unusual rhubarb desserts, you'll love the unique flavor in this No Bake Rhubarb Dessert! It's sure to become one of your favorite rhubarb desserts.
