Step‑by‑Step Instructions for Rhubarb Bars with Cream Cheese
Step 1: Preheat the Oven and Prepare the Dish
Begin by preheating your oven to 350°F (175°C). While it heats, line a 9×13-inch baking dish with parchment paper or lightly grease it to prevent sticking. This setup will ensure your Rhubarb Bars with Cream Cheese come out perfectly and are easy to slice after baking.
Step 2: Make the Crust
In a mixing bowl, combine flour, brown sugar, oats, and melted butter. Use a fork or pastry cutter to mix until the mixture becomes crumbly and resembles coarse sand. Once combined, press the crust mixture evenly into the prepared baking dish. Bake for 15 minutes or until golden brown around the edges, creating a solid base for your bars.
Step 3: Cook the Rhubarb Filling
For the filling, combine chopped fresh rhubarb, sugar, cornstarch, and a splash of water in a saucepan over medium heat. Stir continuously for about 5-7 minutes until the mixture thickens and becomes glossy. Once thickened, remove from heat and stir in vanilla extract, allowing the warm rhubarb filling to infuse with flavor.
Step 4: Assemble the Bars
Evenly spread the warm rhubarb mixture over the pre-baked crust, ensuring it covers the surface completely. This layer of tangy rhubarb will provide a delightful contrast to the creamy topping later. Return the baking dish to the oven and bake for an additional 10-15 minutes, or until the filling is set and slightly bubbly around the edges.
Step 5: Prepare the Cream Cheese Topping
While the bars bake, prepare the cream cheese topping by beating the cream cheese, powdered sugar, and a bit of vanilla extract in a medium bowl until smooth and creamy, about 2-3 minutes. This mixture should be light and fluffy, making it perfect to spread over the cooled rhubarb layer for your Rhubarb Bars with Cream Cheese.
Step 6: Chill and Serve
Once the bars are out of the oven, allow them to cool at room temperature for about 30 minutes. After cooling, spread the cream cheese mixture evenly over the rhubarb layer. For the best texture and flavor, chill the bars in the refrigerator for at least 2 hours before slicing into squares to serve. Enjoy the delightful spring treat!

Rhubarb Bars with Cream Cheese Recipe FAQs
What type of rhubarb should I use for this recipe?
Absolutely! Fresh rhubarb is recommended for the best flavor and texture in your bars. Look for firm, vibrant stalks without dark spots. If fresh isn’t available, frozen rhubarb can be used, but make sure to thaw it completely and drain any excess moisture before adding it to the filling. This prevents the dessert from becoming soggy.

You can store your bars in an airtight container in the refrigerator for up to 5 days. Just be sure to let them cool completely before sealing them up.

Can I freeze Rhubarb Bars with Cream Cheese?
Yes, you can! To freeze, first, allow the bars to cool completely.

Place the wrapped bars in a freezer-safe bag or container. When you’re ready to enjoy, just thaw them in the fridge overnight.
What if my rhubarb filling is too runny?
If your filling turns out too runny, don’t worry! It may just need a little more cooking. Simply return it to the saucepan over medium heat and stir for an additional 2-3 minutes until it thickens to a glossy consistency.
