Banana Rhubarb Cream Cheese Bars
These irresistible Banana Rhubarb Cream Cheese Bars combine a buttery sourdough-style crust, tangy rhubarb filling, sweet banana, and a luscious cream cheese layer into one easy, crowd-pleasing dessert.
The Unexpected Fruit Pairing Your Dessert Table Has Been Missing
Rhubarb gets all the glory in strawberry pies and crumbles, but pair it with ripe banana and a silky cream cheese layer and something genuinely magical happens. These Banana Rhubarb Cream Cheese Bars are one of those unique dessert recipes that surprises everyone at the table, especially the people who swear they don't like rhubarb.
The banana brings natural sweetness and a soft, almost custard-like body to the filling. The rhubarb pushes back with bright, tart acidity. Together, sandwiched between a crisp oat crumble crust and a smooth cream cheese layer, they create a bar that hits every note: sweet, tangy, creamy, and buttery all at once.
If you have been searching for rhubarb desserts that feel a little less expected than the usual strawberry rhubarb crisp, you have found your recipe.
Using quality ingredients and the right equipment makes a genuine difference with layered bar desserts like this one. A good pastry cutter helps you build the perfect crumbly base, and a proper 9x13 pan with parchment ensures clean, bakery-worthy slices every single time.
Why This Rhubarb Recipe Works So Well
Most rhubarb recipes easy enough for a weeknight still call for a mountain of sugar to tame the tartness. Here, the ripe bananas do a lot of that work naturally, which means you get a more complex, layered flavor without an overwhelming sweetness.
Think of these as rhubarb cheesecake bars with a fruit-forward twist. The cream cheese layer is light rather than dense, and it bakes into something almost like a soft cheesecake filling nestled right in the middle of the bar. It is the same idea behind popular rhubarb cream cheese bars and rhubarb cream cheese recipes, but the banana makes it entirely its own.
Chef's Tip: The riper your bananas, the better. Those heavily spotted, almost-too-ripe bananas you would normally save for banana bread are absolutely perfect here. They mash smoothly and bring the most natural sweetness to the filling.
The crust uses rolled oats alongside the flour, giving it a heartier, slightly nutty texture that holds up beautifully to the moist fruit filling. It reads almost like a sourdough fruit bar in terms of that rustic, satisfying base, even without any sourdough starter involved.
Tips for the Best Rhubarb Desserts Easy Enough for Any Baker
A few things will take these bars from good to genuinely great:
- Drain frozen rhubarb thoroughly. Excess moisture is the enemy of a clean, set filling. Pat it dry after thawing.
- Use cold butter for the crumble. Cold butter creates those desirable, distinct clumps rather than a sandy, uniform texture.
- Don't skip the chill time. These bars are sliceable straight from the oven, but they are beautiful after a few hours in the refrigerator. The layers set up, the cream cheese firms, and every slice looks like it came from a bakery case.
- Line your pan with parchment. This one step makes lifting and slicing the entire batch effortless.
Baker's Note: If your rhubarb is particularly tart, you can increase the brown sugar in the fruit layer by up to 2 tablespoons without affecting the texture of the bars.

Banana Rhubarb Cream Cheese Bars
These irresistible Banana Rhubarb Cream Cheese Bars combine a buttery sourdough-style crust, tangy rhubarb filling, sweet banana, and a luscious cream cheese layer into one easy, crowd-pleasing dessert.
Ingredients
- 2 cups all-purpose flour, spooned and leveled
- 1/2 cup rolled oats
- 3/4 cup brown sugar, packed, divided
- 3/4 cup unsalted butter, cold, cubed
- 8 oz cream cheese, softened to room temperature
- 3/8 cup granulated sugar
- 1 large egg, room temperature
- 1 tsp vanilla extract, pure
- 2 ripe bananas, mashed, about 1 cup
- 2 cups fresh or frozen rhubarb, chopped into 0.5-inch pieces, thawed and drained if frozen
- 2 tbsp cornstarch
- 1 tbsp lemon juice, freshly squeezed
- 1/2 tsp cinnamon, ground
- 1/4 tsp salt
Instruction
Preheat your oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking pan and line it with parchment paper, leaving an overhang on the sides for easy lifting.
In a large bowl, combine the flour, rolled oats, 0.5 cup of the brown sugar, and salt. Add the cold cubed butter and use your fingertips or a pastry cutter to work it in until the mixture resembles coarse, clumpy crumbs.
Press about two-thirds of this crumb mixture firmly and evenly into the bottom of the prepared pan to form the crust. Set the remaining crumble aside for the topping.
In a medium bowl, toss the chopped rhubarb with the remaining 0.25 cup brown sugar, cornstarch, lemon juice, and cinnamon until evenly coated. Fold in the mashed bananas. Spread this fruit mixture evenly over the pressed crust.
In a separate bowl, beat the softened cream cheese with the granulated sugar until smooth and fluffy, about 2 minutes. Add the egg and vanilla extract and mix until just combined. Pour and spread this cream cheese layer evenly over the rhubarb-banana filling.
Scatter the reserved oat crumble evenly over the top of the cream cheese layer, pressing it down very gently.
Bake for 40 to 45 minutes, until the top is golden brown and the center is set with only a very slight jiggle.
Remove from the oven and allow the bars to cool completely in the pan on a wire rack, at least 1 hour. For cleanest cuts, transfer to the refrigerator for an additional 1 to 2 hours before slicing into 12 bars.
Equipment
- 9x13-inch baking pan
- Parchment paper
- Large mixing bowl
- Medium mixing bowl
- Hand mixer or stand mixer
- Pastry cutter or fork

- Sharp knife
Notes
Serving, Storing, and Making These Bars Your Own
Serve these bars cold or at cool room temperature. They are lovely on their own, but a small dollop of whipped cream or a light dusting of powdered sugar dresses them up beautifully for a dinner party or potluck.
For variations, consider these easy swaps:
- Strawberry rhubarb version: Replace the banana with 1 cup of sliced fresh strawberries for a more classic rhubarb pairing.
- Ginger spice: Add 0.5 teaspoon of ground ginger to the fruit filling alongside the cinnamon for a warming, slightly spiced version.
- Lemon zest boost: Stir 1 teaspoon of fresh lemon zest into the cream cheese layer for a brighter, more citrusy bar.
These bars store beautifully in the refrigerator for up to 5 days, and they freeze well too, making them one of the most practical rhubarb desserts easy enough to batch-bake and keep on hand all season long.
