Rhubarb Pudding Bars Ingredients
-
For the Crust
• Graham Cracker Crumbs – Base structure for the crust; can be bought pre-made or crushed from whole crackers.
• Granulated Sugar – Sweetens both the crust and rhubarb layer for balanced flavor; use brown sugar for a deeper flavor if desired.
• Unsalted Butter – Binds the graham cracker crust; melted before mixing for easier incorporation. -
For the Rhubarb Layer
• Fresh Rhubarb – Main flavor component, finely chopped for even cooking; do not use leaves as they are toxic; can substitute with frozen, thawed and drained rhubarb.
• Strawberry Jello – Adds sweetness and helps the rhubarb layer to set properly; raspberry or cherry jello can be used as alternatives.
• Cornstarch – Thickens the rhubarb layer for a clean cut; ensure correct measurement for consistency.
• Mini Marshmallows – Create a fluffy layer that adds texture and sweetness; regular marshmallows can be cut into smaller pieces if needed. -
For the Pudding Layer
• Instant Vanilla Pudding – Forms the creamy topping; must be instant for correct texture, as cook-and-serve pudding will not yield the same results.
• Milk – Mixed with pudding powder for a creamy layer; any milk (dairy or non-dairy) can be utilized based on preference.
• Frozen Whipped Topping – Lightens the pudding layer to make it airy; homemade whipped cream can be used but may alter final firmness.
Embrace the delightful journey of crafting these Rhubarb Pudding Bars, and let each layer tell a story of springtime indulgence!
Step‑by‑Step Instructions for Rhubarb Pudding Bars
Step 1: Preheat Your Oven
Start by preheating your oven to 350°F (175°C). This is important as it ensures an even bake for the crust. Prepare your baking dish by greasing a 9×13-inch pan with a bit of butter, making it easier to remove the Rhubarb Pudding Bars later.
Step 2: Prepare the Graham Cracker Crust
In a mixing bowl, combine graham cracker crumbs, granulated sugar, and melted unsalted butter. Mix until the crumbs are evenly moistened. Reserve 2 tablespoons of this mixture for later use on top. Press the remaining mixture firmly into the bottom of your prepared baking dish to form a solid crust.
Step 3: Bake the Crust
Place the crust in the oven and bake for 8–10 minutes, or until it turns lightly golden. Keep an eye on it, as a golden hue signals that it’s ready. Once baked, remove it from the oven and let it cool completely in the pan on a wire rack.
Step 4: Cook the Rhubarb Layer
In a medium saucepan over medium-high heat, combine the finely chopped fresh rhubarb and a small amount of water, cooking for about 3–4 minutes until the rhubarb becomes soft and tender. Stir in granulated sugar, cornstarch, and strawberry jello, mixing until the mixture thickens and becomes clear, which should take another few minutes.
Step 5: Assemble the Layers
Once your rhubarb mixture is ready and slightly cooled, pour it evenly over the set crust in the baking dish. Carefully sprinkle mini marshmallows on top, ensuring even coverage. Place the dish in the refrigerator for at least 2 hours to allow the rhubarb layer to set.
Step 6: Make the Pudding Layer
While your bars chill, prepare the pudding layer. In a clean bowl, whisk together the instant vanilla pudding mix and milk until it thickens, which should take about 2 minutes. Once thickened, gently fold in the thawed whipped topping until the mixture is smooth and creamy.
Step 7: Finish the Rhubarb Pudding Bars
After the rhubarb layer has set, evenly spread the pudding mixture over it. Sprinkle the reserved graham cracker crust mixture on top to add a crunchy texture. Return the dish to the refrigerator and let it chill completely until set, typically for an additional 2 hours, before cutting into bars for serving.

Expert Tips for Rhubarb Pudding Bars

Chill Time Matters: Be patient with chilling times. Each layer needs to set fully to avoid mixing, so plan to refrigerate bars for at least 4 hours before serving.
-
Mix Pudding Properly: For the pudding layer, whisk the instant vanilla pudding mix with milk until thick. Avoid over-mixing; this helps preserve the creamy texture.
-
Serving Tips: Let the bars sit at room temperature for 5-10 minutes before slicing for cleaner cuts. This also enhances the flavors.
-
Store Correctly: Keep your Rhubarb Pudding Bars covered in the fridge for up to 4 days to maintain freshness; flavors improve overnight.

Rhubarb Pudding Bars Recipe FAQs
Why is it important to choose ripe rhubarb?
Absolutely! When selecting rhubarb, look for firm, vibrant stalks without any dark spots or wrinkles. Fresh rhubarb should be a deep pink to bright green color. If you find any wilted or limp stalks, they may not deliver the tangy flavor you’re after.
How should I store Rhubarb Pudding Bars after preparing them?
Keep your Rhubarb Pudding Bars covered in the refrigerator for up to 4 days. Make sure to use an airtight container or wrap them well in plastic wrap to prevent them from drying out or absorbing other odors in the fridge. The flavors actually improve overnight, so they’ll be even more delightful the next day!
Can I freeze Rhubarb Pudding Bars?
Yes, indeed! To freeze your Rhubarb Pudding Bars, slice them first for easy portioning. Wrap each piece tightly in plastic wrap, then place them in an airtight container. They can be frozen for up to 2 months. When you’re ready to enjoy them, just transfer them to the fridge for several hours or overnight to thaw.
What if my rhubarb layer is too runny?
No worries at all! If you find your rhubarb layer is a bit runny, it’s likely due to not cooking it long enough after adding the sugar and cornstarch; it should be thick enough to coat the back of a spoon. If you find yourself in a pinch, you can sprinkle a little more cornstarch over the mixture and cook it on low heat while stirring until it thickens.
Are Rhubarb Pudding Bars safe for pets?
It’s important to note that rhubarb leaves are toxic to pets, but the stalks are safe for human consumption. When serving Rhubarb Pudding Bars, keep them out of reach of pets. Always make sure to store any leftovers securely!
Can I use substitutes in the recipe?
Very much so! If you can’t find fresh rhubarb, feel free to use frozen rhubarb that has been thawed and drained. You can also swap out the strawberry jello for raspberry or cherry jello based on your taste preference! If you’d like a homemade touch, using homemade whipped cream instead of frozen whipped topping will give a richer flavor but may affect the final texture.
