Step‑by‑Step Instructions for Tasty No-Bake Rhubarb Bars
Step 1: Prepare the Crust
Start by crushing about 2 cups of graham crackers into fine crumbs using a food processor or a rolling pin. In a mixing bowl, combine the crumbs with ½ cup of melted butter, mixing until it resembles wet sand. Press this mixture evenly into the bottom of a 9×13 inch dish, creating a firm crust. Place the dish in the refrigerator to chill while you prepare the filling.
Step 2: Cook the Rhubarb Filling
In a medium saucepan, combine 4 cups of chopped fresh rhubarb, 1 cup of sugar, ⅓ cup of cornstarch, and 1 cup of water. Stir everything together and bring to a gentle boil over medium heat. Allow it to cook for 20 to 30 minutes, stirring occasionally, until the rhubarb is soft and the mixture thickens to a jam-like consistency. Remove it from heat and let it cool completely before layering.
Step 3: Whip the Cream Topping
While the rhubarb filling cools, pour 1 cup of heavy cream into a mixing bowl. Using an electric mixer, whip the cream on high speed until stiff peaks form, which should take about 3 to 5 minutes. Gently fold in 1 cup of mini marshmallows for sweetness and lightness. Set this fluffy mixture aside as you assemble the layers of your Tasty No-Bake Rhubarb Bars.
Step 4: Layer the Rhubarb Filling
Once the rhubarb filling is cool, take the chilled crust out of the refrigerator. Spoon the cooled rhubarb mixture evenly over the crust, spreading it out with a spatula to ensure a smooth, even layer. Make sure it is well-distributed; this gives your bars that perfect tartness throughout.
Step 5: Add the Whipped Cream Layer
Now, take the whipped cream and marshmallow mixture and gently spread it over the cooled rhubarb layer. Use a spatula to create an even topping, taking care not to mix the layers too much. This airy, fluffy layer will balance out the tartness of the rhubarb, making your no-bake bars a delightful treat.
Step 6: Prepare the Vanilla Pudding Layer
Next, follow the package instructions to prepare 1 box of vanilla pudding mix, which usually involves whisking the mix with 2 cups of milk until it thickens—about 2 minutes. Once thick, gently spread this creamy pudding layer over the whipped cream layer, ensuring it covers the entire surface for a luscious finish.
Step 7: Chill and Serve
Sprinkle a portion of the reserved graham cracker crumbs on top for a final touch. Cover the dish with plastic wrap and refrigerate your Tasty No-Bake Rhubarb Bars for at least 6 hours, or overnight for best results. This allows the layers to set beautifully. Once firm, cut into squares with a wet knife for clean edges, and serve cold for a refreshing summer dessert.

Tasty No-Bake Rhubarb Bars Recipe FAQs
How do I choose fresh rhubarb?
Look for firm, vibrant rhubarb stalks that are free of dark spots or wilting. The stalks should feel crisp and have a vibrant color, indicating freshness. If you can only find frozen rhubarb, ensure it’s properly thawed and drained to avoid excess moisture in your filling.
What is the best way to store Tasty No-Bake Rhubarb Bars?
Store your bars in an airtight container in the refrigerator, where they will last for up to 4 days. They actually develop even better flavor after sitting overnight! If you want to enjoy them later, they can be frozen for up to 2 months. Just wrap individual portions tightly in plastic wrap or foil to prevent freezer burn.
Can I freeze Tasty No-Bake Rhubarb Bars?
Absolutely! To freeze, make sure the bars are fully set and cut into squares. Wrap each square in plastic wrap, followed by aluminum foil, to keep them fresh. When ready to eat, just thaw them overnight in the refrigerator. They are best enjoyed chilled, so no need to reheat!
What should I do if my rhubarb filling is too runny?
If your filling is runny, it likely hasn’t been cooked long enough for the cornstarch to activate. Next time, make sure to boil the rhubarb mixture for 20-30 minutes until it thickens to a jam-like texture. If you find yourself with a runny mixture already, you can cook it down further over low heat until it reaches the desired consistency.
Are Tasty No-Bake Rhubarb Bars suitable for pets or those with allergies?
These bars contain sugar and heavy cream, which are not suitable for dogs or cats. If you have allergies, be sure to substitute any non-allergenic ingredients as needed, like using coconut cream instead of heavy cream or almond milk instead of regular milk in the pudding. Always check ingredient labels if you have specific allergies to ensure safety!
