Key Ingredients for Perfect Rhubarb Pudding Bars
The success of Rhubarb Pudding Bars hinges on selecting the right ingredients. While the recipe itself is straightforward, each component plays a critical role in achieving that signature taste and texture.
Ingredient | Quantity | Purpose |
---|---|---|
Fresh rhubarb (chopped) | 4 cups | Provides tart, fruity flavor for the filling |
Granulated sugar | 1 cup (plus extra if needed) | Sweetens and balances the tartness of rhubarb |
Cornstarch | 2 tablespoons | Thickens the rhubarb filling |
Butter (unsalted) | 1 cup (softened) | Creates a rich, crumbly crust |
All-purpose flour | 2 cups | Forms the structure of the crust |
Powdered sugar | ½ cup | Adds sweetness and a tender texture to the crust |
Vanilla pudding mix (instant or cook-and-serve) | 1 package (3.4 oz) | Adds the creamy middle layer |
Milk | 2 cups | Used to prepare the pudding |
Lemon zest (optional) | 1 teaspoon | Adds brightness to the filling |
Fresh strawberries (optional) | 2 cups (for variation) | Adds sweetness when making strawberry-rhubarb version |
Fresh Rhubarb: Picking and Preparing
Fresh rhubarb is the star of the show, and its quality will directly influence your final dessert. Look for firm, crisp stalks with vibrant pink to red coloring—avoid limp or blemished pieces. Before using, wash thoroughly and trim away any leaves, as they’re toxic. Cut the stalks into small, even pieces so they cook uniformly in the pudding mixture. For a slightly milder tartness, you can macerate the chopped rhubarb with a little sugar before baking.
The Role of Creamy Pudding in the Recipe
The pudding layer is what transforms this dessert from simple fruit bars into a creamy delight. Vanilla pudding is a classic choice, offering a smooth, sweet counterbalance to the rhubarb’s tang. You can use either instant pudding for convenience or homemade pudding for a richer, more decadent flavor. The pudding acts as a binding layer, holding the rhubarb filling together and adding that melt-in-your-mouth texture.
Choosing the Right Crust Base
A sturdy yet tender crust is essential for Rhubarb Pudding Bars. Many recipes use a shortbread-style base made from butter, sugar, and flour, which provides a crumbly yet stable foundation. Others opt for a graham cracker crust for a slightly sweeter, more rustic touch. Whichever you choose, ensure it’s fully baked before adding the filling to prevent sogginess.

Step-by-Step Recipe for Rhubarb Pudding Bars
Creating Rhubarb Pudding Bars is a rewarding process when you break it down into manageable steps.
Preparing the Crust
- Preheat the oven to 350°F (175°C).
- In a mixing bowl, combine 1 cup butter, 2 cups all-purpose flour, and ½ cup sugar.
- Mix until crumbly, then press firmly into the bottom of a greased 9×13-inch baking dish.
- Bake for 15 minutes, or until lightly golden, and set aside to cool slightly.
Making the Rhubarb Filling
- In a saucepan, combine 4 cups chopped rhubarb, 1 cup sugar, and 2 tablespoons cornstarch.
- Cook over medium heat until the mixture thickens and the rhubarb softens.
- Remove from heat and allow to cool slightly before layering over the crust.
Assembling and Baking
- Prepare vanilla pudding according to package instructions (or make from scratch if preferred).
- Spread the pudding evenly over the rhubarb layer.
- Bake for an additional 20–25 minutes until the filling is set and slightly bubbling at the edges.
- Cool completely before cutting into bars.
Expert Tips for the Best Rhubarb Pudding Bars
Making Rhubarb Pudding Bars is not just about following a recipe — it’s about understanding how each step affects the final result. If you want your dessert to stand out, these tips can make all the difference.
- Choose Rhubarb in Season
Fresh, in-season rhubarb is sweeter, more colorful, and less fibrous than off-season options. Peak rhubarb season usually runs from April through June in most regions. Out-of-season stalks can be overly tart and require extra sugar to balance. - Blanch for Milder Flavor
If your rhubarb is very sour, blanching it in boiling water for 30 seconds, then cooling quickly in ice water, can reduce the sharpness without affecting texture. - Mix Sweeteners
Instead of using only white sugar, try a blend of brown sugar and white sugar. Brown sugar adds a hint of caramel-like richness that complements the tangy rhubarb and creamy pudding layer. - Add a Hint of Citrus
A teaspoon of lemon or orange zest in the filling brightens the flavor and adds depth to the overall taste profile. - Don’t Skimp on Chilling Time
The chilling process is not just about cooling the dessert — it allows the crust to firm up, the pudding to set, and the flavors to meld together into a harmonious bite.
By incorporating these techniques, your Rhubarb Pudding Bars won’t just be good — they’ll be the kind of dessert people request again and again.
Delicious Variations to Try
Strawberry-Rhubarb Pudding Bars
This variation is a summer staple. Strawberries bring a fragrant sweetness that pairs beautifully with rhubarb’s sharpness. For best results, choose ripe strawberries and slice them thinly so they cook evenly. If your strawberries are very juicy, sprinkle them with a little cornstarch before layering them with rhubarb to prevent a watery filling.
Blueberry-Rhubarb Pudding Bars
Blueberries offer a mild sweetness and a pop of color. This twist works especially well with a graham cracker crust, as the flavor combination feels reminiscent of a berry cheesecake but with the signature pudding creaminess.
Apple-Rhubarb Pudding Bars
Adding thinly sliced apples to the rhubarb layer provides a naturally sweet, slightly spiced undertone. Consider sprinkling a little cinnamon or nutmeg into the mix for a cozy autumn feel.
Chocolate Drizzle Rhubarb Pudding Bars
For a more decadent twist, drizzle cooled bars with melted white or dark chocolate. This adds visual appeal and an extra layer of indulgence.
These variations allow you to customize Rhubarb Pudding Bars to match the season, the occasion, or simply your mood.
Pairing Ideas: What Goes Best with Rhubarb Pudding Bars
Pairings can take your dessert experience from pleasant to unforgettable. The key is balancing flavors so that nothing overshadows the delicate interplay of tart rhubarb and creamy pudding.
- Tea Pairings: Earl Grey’s bergamot essence complements the fruity tang, while chamomile brings a soothing counterpoint. If you like herbal teas, mint tea pairs refreshingly well.
- Coffee Pairings: A mild roast coffee with nutty notes works beautifully, especially when served with a breakfast or brunch spread.
- Alcohol Pairings: Light, slightly sweet wines like Moscato or rosé enhance the dessert’s fruity profile. For a cozy winter pairing, try a small glass of dessert sherry.
- Toppings: A dollop of mascarpone cheese whipped with a little honey creates a luxurious finish. Alternatively, lightly sweetened yogurt can offer a tangy contrast.
By thoughtfully pairing Rhubarb Pudding Bars, you create a complete dining experience rather than just a dessert.
Storing and Freezing Rhubarb Pudding Bars
Proper storage is essential if you want to enjoy your Rhubarb Pudding Bars beyond the day they’re baked.
- Short-Term Storage: Keep bars in an airtight container in the fridge. Layering parchment paper between stacked bars prevents sticking. These bars are best eaten within four days for peak flavor and texture.
- Freezing Tips: Wrap individual bars tightly in plastic wrap and then place them in a freezer-safe bag or container. When ready to enjoy, thaw them in the fridge overnight rather than at room temperature to avoid condensation making the crust soggy.
- Serving After Freezing: For the best texture after freezing, consider adding a fresh dusting of powdered sugar or a light whipped cream topping just before serving.
Freezing is a great option for making Rhubarb Pudding Bars ahead of time for special occasions.

FAQs
1. Can I make Rhubarb Pudding Bars without pre-baking the crust?
It’s not recommended. Pre-baking creates a firm base that prevents the pudding and rhubarb filling from soaking into the crust, which can make it soggy.
2. Can I substitute other fruits for rhubarb?
Yes, though the flavor profile will change. Berries, apples, or peaches work well, but you’ll lose the signature tartness that makes Rhubarb Pudding Bars unique.
3. How do I prevent my pudding layer from becoming runny?
Ensure the rhubarb filling is cooled before adding the pudding, and allow adequate chilling time after baking. Using slightly less milk than the pudding package suggests can also help it set firmer.
4. Is it possible to make these bars sugar-free?
Yes, use a sugar substitute suitable for baking, such as stevia or monk fruit sweetener. Keep in mind, this may slightly alter texture and taste.
5. Can I make Rhubarb Pudding Bars gluten-free?
Absolutely — substitute the crust flour with a 1:1 gluten-free baking blend. Just watch the texture, as some blends may yield a slightly softer crust.
6. What’s the best way to cut clean slices?
Chill the bars fully, then use a sharp knife dipped in warm water and wiped dry between cuts. This helps maintain crisp edges and distinct layers.

Rhubarb Pudding Bars Recipe
- Prep Time: 20
- Cook Time: 45
- Total Time: 1 hr 5 min
- Yield: 12 bars 1x
- Category: Dessert
- Method: Baking
- Cuisine: American
Description
Ingredients
4 cups fresh rhubarb, chopped
1 ½ cups granulated sugar
1 ½ cups all-purpose flour
1 teaspoon baking powder
¼ teaspoon salt
3 large eggs
1 teaspoon vanilla extract
1 cup milk
½ cup butter, melted
Instructions
Prep
-
Preheat oven to 350°F (175°C).
-
Grease or line a 9×13-inch (23×33 cm) pan with parchment, leaving overhang for easy lifting.
Prep the rhubarb
-
Wash, trim, and chop 4 cups rhubarb into ½-inch pieces.
-
If very tart, toss with 2–3 Tbsp of the sugar from your measured amount and set aside.
Mix dry ingredients
-
In a large bowl, whisk together: 1½ cups all-purpose flour, 1½ cups granulated sugar, 1 tsp baking powder, ¼ tsp salt.
Mix wet ingredients
-
In a separate bowl, whisk 3 large eggs, 1 cup milk, and 1 tsp vanilla extract until smooth.
-
Slowly whisk in ½ cup melted butter (cooled slightly) until combined.
Make the custardy batter
-
Pour the wet mixture into the dry mixture and whisk just until no dry streaks remain (don’t overmix).
-
Fold in the chopped rhubarb gently so it’s evenly distributed.
Pan & level
-
Pour batter into the prepared pan and spread evenly to corners. Tap the pan lightly on the counter to release air bubbles.
Bake
-
Bake at 350°F (175°C) for 35–45 minutes, until the top is golden and the center is just set.
-
A tester inserted near the center should come out with a few moist crumbs (not wet batter). The edges will look lightly browned.
Cool & set
-
Cool in the pan on a rack for at least 45–60 minutes; the pudding-like center firms as it cools.
-
For clean cuts, chill 1–2 hours.
Slice & serve
-
Use the parchment overhang to lift out. Cut into bars with a sharp knife, wiping the blade between cuts.
-
Optional: dust with powdered sugar or serve with a small dollop of whipped cream.
Store
-
Refrigerate in an airtight container up to 4 days.
-
To freeze, wrap bars individually and freeze up to 3 months; thaw overnight in the fridge.
Pro tips:
-
If using very juicy rhubarb, toss it with 1 Tbsp flour before folding in.
-
For extra “pudding” richness, swap half the milk for half-and-half.
Notes
Sweetness level – Rhubarb is naturally tart; if you prefer a sweeter bar, increase sugar by ¼–½ cup.
Fresh vs. frozen rhubarb – Frozen rhubarb works well; thaw and drain excess liquid before adding to batter.
Texture – These bars have a soft, custardy center, so they may appear slightly jiggly when hot. They will firm up as they cool.
Serving idea – Delicious on their own, but even better with a dusting of powdered sugar, a drizzle of cream, or a scoop of vanilla ice cream.
Cutting clean slices – Chill before slicing for neat edges; wipe knife between cuts.
Storage tip – Keep refrigerated for freshness; bring to room temperature before serving for best flavor.
