Banana Rhubarb Cream Cheese Bars
These Banana Rhubarb Cream Cheese Bars combine a buttery sourdough-style crust, tangy rhubarb filling, and silky cream cheese layer into one uniquely irresistible dessert that is easy enough for any home baker.
The Unique Dessert You Did Not Know You Needed
If you have ever stared at a bunch of spotty bananas and a pile of rhubarb stalks and wondered what on earth to do with both at once, this recipe was made for you. These Banana Rhubarb Cream Cheese Bars are one of those unique dessert recipes that sounds a little unexpected but delivers in the most satisfying, crowd-pleasing way imaginable.
The combination works because bananas bring natural sweetness and a soft, jammy body that tempers rhubarb's sharp tartness. Together, they create a filling that is complex and layered without being fussy. Spread that over a buttery, shortbread-style crust and finish it with a cloud of vanilla cream cheese, and you have something that feels like a rhubarb cheesecake bar and a fruit crumble bar had the most delicious baby.
Why This Rhubarb Recipe Stands Out
Rhubarb desserts are having a well-deserved moment. Most people stick to strawberry-rhubarb pie, and while that classic is never wrong, there is a whole world of rhubarb desserts easy enough for a weeknight that go far beyond it. This recipe is one of them.
What makes these bars special:
- Three distinct layers that each bring something different in texture and flavor
- No mixer required for the crust, making the prep genuinely approachable
- Freezer-friendly, so you can make a batch now and enjoy it weeks later
- A flavor profile that surprises people in the best way possible
Think of them as rhubarb cream cheese bars with a tropical twist. The banana is subtle once baked, acting more as a natural sweetener and binder than a bold flavor statement. The rhubarb is the star, and the cream cheese layer ties everything together with richness and tang.
Using quality ingredients and the right baking pan makes a genuine difference when making layered bar desserts like these. A heavy-gauge 9x13 pan ensures even baking, and full-fat block cream cheese (not the spreadable kind in a tub) gives you that smooth, cheesecake-like texture that makes these bars truly special.
Tips for Working With Rhubarb
If you are new to rhubarb recipes, here are a few things worth knowing before you start:
- Always cook rhubarb before baking it into bars. Raw rhubarb releases too much liquid in the oven, which can make your crust soggy.
- Taste your rhubarb. Some stalks are more sour than others. If yours is very tart, you can add an extra tablespoon of sugar to the filling.
- Frozen rhubarb is perfectly fine. Thaw it and drain it well before using.
For the cream cheese layer, make sure your block is fully softened before you start mixing. Cold cream cheese leads to lumps, and lumps are the enemy of a silky smooth top layer.
Chef's Tip: Do not skip the chill time. These bars are good at room temperature, but they are great cold. The cream cheese layer firms up into something closer to a proper cheesecake filling, and the flavors meld together in a way that only happens after a few hours in the fridge.
A Crust Worth Talking About
The base here is inspired by sourdough fruit bars in its rustic, slightly crumbly character, though there is no sourdough starter involved. It is a simple press-in shortbread made with cold butter, flour, sugar, and salt. Pressing it into the pan takes about two minutes, and blind-baking it for a short stint before adding the filling keeps it from turning soft under all that moisture.
This is also one of those rhubarb cream cheese recipes where the crust-to-filling ratio really matters. Too thin and it disappears. Too thick and it overpowers. The amounts here hit the sweet spot.

Banana Rhubarb Cream Cheese Bars
These Banana Rhubarb Cream Cheese Bars combine a buttery sourdough-style crust, tangy rhubarb filling, and silky cream cheese layer into one uniquely irresistible dessert that is easy enough for any home baker.
Ingredients
- 2 cups all-purpose flour, plus extra for dusting
- 3/4 cup unsalted butter, cold, cut into cubes
- 1/4 cup granulated sugar, for the crust
- 1/4 tsp salt
- 2 1/2 cups rhubarb, fresh or frozen, chopped into 0.5-inch pieces
- 2 ripe bananas, mashed, about 1 cup
- 1/2 cup granulated sugar, for the rhubarb filling
- 2 tbsp cornstarch
- 1 tbsp lemon juice, freshly squeezed
- 8 oz cream cheese, full-fat, softened to room temperature
- 1 large egg, room temperature
- 3/8 cup powdered sugar, for the cream cheese layer
- 1 tsp vanilla extract, pure
Instruction
Preheat the oven to 350 degrees F (175 degrees C). Grease a 9x13-inch baking pan and line it with parchment paper, leaving an overhang on two sides for easy lifting.
Make the crust: In a large bowl, combine the flour, granulated sugar, and salt. Add the cold butter cubes and use your fingertips or a pastry cutter to work the butter into the flour until the mixture resembles coarse crumbs with some pea-sized pieces remaining. Press the mixture firmly and evenly into the bottom of the prepared pan to form a compact crust layer.
Blind-bake the crust for 12 to 14 minutes until the edges are just barely golden. Remove from the oven and let it cool for 5 minutes while you prepare the fillings.
Make the rhubarb-banana filling: In a medium saucepan over medium heat, combine the chopped rhubarb, mashed bananas, granulated sugar, cornstarch, and lemon juice. Stir constantly and cook for 6 to 8 minutes until the rhubarb softens and the mixture thickens noticeably. Remove from heat and let it cool for 5 minutes.
Make the cream cheese layer: In a medium bowl, beat the softened cream cheese with the powdered sugar and vanilla extract until completely smooth and fluffy. Add the egg and mix until just combined. Do not overmix.
Assemble the bars: Spread the rhubarb-banana filling evenly over the pre-baked crust. Dollop the cream cheese mixture over the top, then use an offset spatula or the back of a spoon to gently spread it into an even layer.
Bake for 28 to 32 minutes, until the cream cheese layer is set at the edges but has a very slight jiggle in the very center. It will firm up as it cools.
Allow the bars to cool completely in the pan at room temperature for 30 minutes, then transfer to the refrigerator and chill for at least 2 hours before slicing.
Lift the bars out using the parchment overhang, slice into 12 even squares, and serve chilled.

Notes
Serving and Storing These Bars
Slice them into 12 generous squares or 16 smaller bites if you are serving a crowd. They look beautiful on a platter with a light dusting of powdered sugar or a few thin slices of fresh banana alongside.
Leftovers keep wonderfully in the fridge for up to five days, and these bars are one of those desserts with rhubarb that genuinely improves overnight. The layers settle, the flavors deepen, and every bite becomes more cohesive. If you are making them for a gathering, baking the day before is not just acceptable, it is actually the move.
