Rhubarb Cheesecake Bars: A Tart and Sweet Symphony

As a chef, certain ingredients evoke memories, and rhubarb holds a special place in my heart.

Those ruby-red rhubarb stalks, when paired with something sweet and creamy, were pure magic. This recipe for Rhubarb Cheesecake Bars captures that very essence – the delightful tang of rhubarb softened by a rich, velvety cheesecake filling, all nestled on a buttery, crumbly oat crust. It’s a dessert that whispers of spring and early summer, a perfect balance of bright acidity and comforting sweetness that always brings a smile to my face and a chorus of happy sighs from anyone who tastes it.

Equipment Needed

To create these delightful Rhubarb Cheesecake Bars, you’ll want to have the following on hand:

• Jelly roll pan: A 15 1/2 x 10 1/2 x 1 inch pan is specified for the perfect bar thickness.
• Large bowls: For mixing the crust/crumble and the filling.
• Electric mixer: A hand mixer or stand mixer will be invaluable for achieving a smooth cheesecake filling.
• Rubber spatula or spoon: For stirring and spreading.
• Measuring cups and spoons: For accurate ingredient measurements.
• Cooling rack: Essential for allowing the bars to cool properly.
• Sharp knife: For slicing the cooled bars.

Instructions

The beauty of these Rhubarb Cheesecake Bars lies in their straightforward assembly, creating a layered marvel of flavor and texture. Follow these steps carefully to achieve perfection:

1. Preheat and Prepare: Begin by heating your oven to 350 degrees Fahrenheit. Next, grease the bottom and sides of your jelly roll pan (measuring 15 1/2 x 10 1/2 x 1 inch) with shortening, or generously spray it with cooking spray. This crucial step ensures your bars won’t stick.

2. Create the Crumb Mixture: In a large bowl, combine the all-purpose flour, quick-cooking oats (or old-fashioned oats), packed brown sugar, softened butter, salt, and baking soda. Using your hands, a pastry blender, or the paddle attachment of your electric mixer on low speed, beat these ingredients together until the mixture resembles coarse crumbs.

3. Form the Base: Take approximately 4 cups of the crumb mixture and press it firmly and evenly into the prepared jelly roll pan. This will form the delightful crust for your cheesecake bars. Set the remaining crumb mixture aside for the topping.

4. Prepare the Cheesecake Filling: In another large bowl, combine the softened cream cheese, eggs, granulated sugar, and vanilla. Beat these ingredients with an electric mixer on medium speed until they are well blended and smooth. Be sure to scrape down the sides of the bowl as needed.

5. Incorporate the Rhubarb: Gently stir the chopped fresh rhubarb into the cream cheese mixture. Aim for an even distribution throughout the filling.

6. Assemble the Bars: Spread the rhubarb-spiked cheesecake filling evenly over the pressed crumb crust in the jelly roll pan.

7. Add the Topping: Sprinkle the remaining crumb mixture evenly over the top of the cheesecake filling. Press lightly to help it adhere.

8. Bake to Perfection: Place the jelly roll pan in the preheated oven. Bake for 40 to 50 minutes, or until the center of the cheesecake is set. The edges should be lightly golden, and the center should no longer appear jiggly.

9. Initial Cooling: Once baked, carefully remove the pan from the oven and let the bars cool for 30 minutes in the pan on a wire rack. This initial cooling period allows the structure to firm up before refrigeration.

10. Chill Thoroughly: After the initial cooling, cover the pan with plastic wrap or foil. Refrigerate the bars for at least 3 hours, but no longer than 48 hours. Chilling is crucial for the cheesecake to set properly and for the flavors to meld.

11. Slice and Serve: Once thoroughly chilled, cut the bars into 10 rows by 6 rows to create approximately 48 individual bars. For the cleanest cuts, you can run a sharp knife under hot water and dry it between slices.

12. Storage: Store the cut bars covered in the refrigerator.

Expert Tips & Tricks

• Rhubarb Prep: Ensure your rhubarb is chopped into relatively uniform pieces. This helps it cook evenly within the cheesecake filling. If your rhubarb is particularly tart, you might find it benefits from a light maceration with a tablespoon of sugar before being added to the filling, though this recipe balances it out well.
• Cream Cheese Temperature: For a truly smooth and lump-free cheesecake filling, ensure your cream cheese is fully softened. Leaving it out at room temperature for at least an hour, or gently warming it in the microwave for very short bursts, is key.
• Oat Choice: Both quick-cooking oats and old-fashioned oats will work here. Quick-cooking oats will provide a slightly finer crumb, while old-fashioned oats will offer a bit more texture. The difference is subtle, so choose your preference.
• Pan Size Matters: The specified jelly roll pan size is important for achieving the correct bar thickness. If you use a larger pan, your bars will be thinner and may bake faster. A smaller pan will result in thicker bars that require a longer baking time.
• Testing for Doneness: The center should be set, meaning it’s firm to the touch and doesn’t have a significant wobble. If you’re unsure, a toothpick inserted near the center should come out mostly clean, with maybe a few moist crumbs attached.
• Chilling is Non-Negotiable: Don’t rush the chilling process. This is where the magic happens, allowing the cheesecake to firm up and the flavors to deepen. A minimum of 3 hours is essential for the perfect texture.

Serving & Storage Suggestions

These Rhubarb Cheesecake Bars are a delight served chilled, straight from the refrigerator. Their tart-sweet profile makes them a fantastic standalone treat. For an extra touch of indulgence, consider serving them with a dollop of whipped cream or a light dusting of powdered sugar. A sprig of fresh mint can also add a beautiful visual appeal and a hint of freshness.

Leftovers should be stored covered in the refrigerator. They will keep well for up to 4 days. Due to the dairy content, these bars are not recommended for freezing long-term, as the texture of the cheesecake may be compromised upon thawing. If you need to store them for longer, ensure they are tightly wrapped to prevent drying out.

Variations & Substitutions

While this recipe is wonderfully balanced as is, there’s always room for a little culinary creativity!

• Gluten-Free Crust: For a gluten-free option, you can substitute the all-purpose flour with a good quality gluten-free all-purpose baking blend. Ensure the blend contains xanthan gum.
• Nutty Crust: Add a half cup of chopped walnuts or pecans to the crumb mixture for an added layer of flavor and texture.
• Berry Boost: While rhubarb is the star, consider adding a small handful of fresh raspberries or blueberries along with the rhubarb for a mixed berry surprise.
• Spice It Up: A pinch of cinnamon or nutmeg in the crust mixture can add a lovely warmth.

FAQs

Q: My cheesecake filling has lumps. What did I do wrong?
A: This is usually because the cream cheese was not softened enough. Ensure it’s at room temperature for at least an hour before mixing for a smooth, creamy consistency.

Q: Can I use frozen rhubarb instead of fresh?
A: Yes, you can. Thaw the frozen rhubarb completely and drain off any excess liquid before adding it to the filling. You may need to bake the bars slightly longer.

Q: How do I get clean cuts on my bars?
A: A sharp knife is key. Running the knife under hot water and drying it between cuts will help prevent sticking and create very clean edges.

Q: My bars seem to be browning too quickly on top.
A: If you notice the topping browning too fast, you can loosely tent the pan with aluminum foil for the remainder of the baking time.

Q: What’s the best way to store leftovers if I don’t have a whole pan?
A: Once cut, store the bars in an airtight container in the refrigerator to maintain their freshness and prevent them from drying out.
