Step‑by‑Step Instructions for Tasty No Bake Rhubarb Bars
Step 1: Prepare the Crust
Start by crushing enough graham crackers to yield about 2 cups of crumbs. In a medium bowl, combine the crumbs with melted butter until the mixture resembles wet sand. Press this mixture firmly into the bottom of a 9×13-inch dish to form an even layer. Place the dish in the refrigerator for at least 30 minutes to set while you work on the rhubarb filling.
Step 2: Cook the Rhubarb
In a large pot, add 4 cups of chopped fresh rhubarb along with 1 cup of sugar, 2 tablespoons of cornstarch, and 1/2 cup of water. Stir the mixture well and bring it to a boil over medium heat. Reduce the heat and simmer for about 20-30 minutes, stirring occasionally until the rhubarb breaks down into a thick, jam-like consistency. Remove from heat and let it cool slightly before transferring to a bowl.
Step 3: Cool the Rhubarb
Allow the rhubarb filling to cool completely at room temperature for about 30 minutes. This is crucial to prevent the whipped cream layer from melting when you assemble the Tasty No Bake Rhubarb Bars. Once cooled, you can set it aside while you whip the cream.
Step 4: Whip the Cream
In a large mixing bowl, pour in 2 cups of heavy cream and whip it using an electric mixer on medium-high speed until stiff peaks form, about 3 to 5 minutes. Gently fold in 1 cup of mini marshmallows with a spatula, making sure to maintain the airy texture of the whipped cream. Set this mixture in the fridge while you layer the bars.
Step 5: Layer the Bars
Once the rhubarb filling has cooled and the whipped cream is ready, carefully spread the rhubarb mixture evenly over the prepared crust in the dish. Then layer the whipped cream mixture on top, spreading it gently across the rhubarb. Finally, prepare 1 package of vanilla pudding according to package instructions and spread it over the whipped cream layer for a creamy finish.
Step 6: Finish and Chill
To complete your Tasty No Bake Rhubarb Bars, sprinkle reserved graham cracker crumbs over the pudding layer for added texture. Cover the dish with plastic wrap and refrigerate for at least 6 hours, or preferably overnight, allowing all the layers to set and meld together beautifully.
Step 7: Cut and Serve
After chilling, remove the bars from the refrigerator. Using a sharp, wet knife, slice the dessert into squares for serving. Serve chilled, and if desired, pair them with fresh berries or a scoop of vanilla ice cream for an extra delightful treat!

Expert Tips for Tasty No Bake Rhubarb Bars
-
Thick Filling: Ensure the rhubarb mixture has reached a jam-like consistency. This prevents the bars from becoming too runny.
-
Cooling Layers: Allow each layer to cool completely before adding the next. This helps maintain the structure and prevents melting.
-
Chill Time: Be patient and let the assembled bars chill for the full 6 hours, or overnight if possible. Cutting too early results in messy servings.
-
Fresh Rhubarb: Use fresh rhubarb whenever possible for optimal flavor. If using frozen, make sure it’s fully thawed and drained to avoid excess moisture.
-
Whipped Cream Tips: Whip the cream to stiff peaks, but don’t overbeat it. This ensures a light, airy topping that won’t collapse in the bars.
Make Ahead Options
These Tasty No Bake Rhubarb Bars are a fantastic choice for meal prep enthusiasts! You can prepare the crust and rhubarb filling up to 24 hours in advance, allowing you to save time when you’re ready to assemble. Start by making the crust and refrigerating it, then cook the rhubarb filling and let it cool completely before storing it in an airtight container in the fridge. To ensure each layer maintains its wonderful texture, keep the whipped cream separate and whip it right before layering. When you’re ready to serve, simply layer the cooled rhubarb over the crust, add the whipped cream, topped with vanilla pudding, and refrigerate for at least 6 hours or overnight. This way, your dessert will be just as delicious while easing your preparation stress!
