Ingredients

For the crust:

• 1 ½ cups (188g) all-purpose flour
• ½ cup (100g) granulated sugar
• ½ teaspoon salt
• ½ cup (1 stick, 113g) cold unsalted butter, cut into small cubes

For the rhubarb filling:

• 3 cups (about 450g) fresh or frozen rhubarb, chopped into ½-inch pieces (if frozen, do not thaw)
• ½ cup (100g) granulated sugar
• 1 tablespoon fresh lemon juice
• 2 tablespoons cornstarch
• 1 teaspoon vanilla extract

For the cheesecake layer:

• 16 oz (450g) cream cheese, softened to room temperature
• ½ cup (100g) granulated sugar
• 2 large eggs, room temperature
• 1 teaspoon vanilla extract

For the crumble topping:

• 1 cup (125g) all-purpose flour
• ½ cup (100g) packed light brown sugar
• ½ teaspoon ground cinnamon
• ¼ teaspoon salt
• ½ cup (1 stick, 113g) cold unsalted butter, cut into small cubes

Optional Substitutions

• Gluten-free: Use a 1:1 gluten-free all-purpose flour blend for the crust and crumble. The texture will be slightly more tender, but still delicious.
• Dairy-free: Substitute the butter with a high-quality vegan butter stick (like Miyoko’s) and use dairy-free cream cheese. The result will be slightly less rich, but very tasty.
• Lower sugar: Reduce the sugar in the rhubarb filling to ¼ cup (50g) if you prefer a tarter bar, or use a monk fruit blend for the crust and crumble. Note that sugar helps the rhubarb release juices and set properly.
• Egg substitute: Replace each egg with ¼ cup unsweetened applesauce or a flax egg (1 tablespoon ground flaxseed + 3 tablespoons water per egg). The texture will be a bit denser.
• Other fruit: Substitute rhubarb with fresh or frozen strawberries, cherries, or a mix. If using very juicy fruits like strawberries, increase the cornstarch to 3 tablespoons to prevent a runny filling.
• Different crust: Swap the shortbread crust for a graham cracker crust (1 ½ cups graham cracker crumbs + ¼ cup sugar + ½ cup melted butter). Press into pan and bake at 350°F for 8 minutes before adding filling.
• Spices: Add ¼ teaspoon ground ginger or cardamom to the crumble for a warm flavor twist.

Instructions

1. Preheat the oven to 350°F (175°C). Line a 9×13-inch baking pan with parchment paper, leaving overhang on the long sides for easy removal.
2. Make the crust: In a medium bowl, whisk together the flour, sugar, and salt. Add the cold butter cubes and use a pastry cutter or your fingers to work the butter into the flour until the mixture resembles coarse sand with some small pea-sized butter pieces. Press the mixture evenly into the bottom of the prepared pan. Bake for 15 minutes, until lightly golden. Set aside to cool slightly while you prepare the filling.
3. Make the rhubarb filling: In a medium saucepan, combine the chopped rhubarb, sugar, lemon juice, cornstarch, and vanilla. Cook over medium heat, stirring frequently, until the rhubarb breaks down and the mixture thickens, about 8–10 minutes. Remove from heat and let cool for 10 minutes.
4. Make the cheesecake layer: In a large bowl, beat the softened cream cheese with an electric mixer until smooth. Add the sugar and beat until combined, then add the vanilla. Add the eggs one at a time, beating just until incorporated — do not overmix. Scrape down the sides of the bowl as needed.
5. Assemble: Pour the cheesecake mixture over the pre-baked crust and spread it evenly. Spoon the cooled rhubarb filling over the cheesecake in small dollops, then gently swirl with a knife or toothpick for a marbled effect.
6. Make the crumble topping: In a medium bowl, whisk together the flour, brown sugar, cinnamon, and salt. Add the cold butter cubes and use your fingers or a pastry cutter to work the butter into the dry ingredients until the mixture forms large, clumpy crumbs. Sprinkle the crumble evenly over the rhubarb layer.
7. Bake: Place the pan in the preheated oven and bake for 35–40 minutes, or until the edges are set and the center is slightly jiggly (like a cheesecake). The crumble should be golden brown.
8. Cool: Remove from the oven and let cool completely on a wire rack (about 1 hour). Then refrigerate for at least 4 hours, preferably overnight, to set the layers fully.
9. Slice: Use the parchment overhang to lift the bars onto a cutting board. Slice into squares using a sharp knife, wiping the blade clean between cuts for neat edges.
10. Serve: Enjoy cold or at room temperature. Store leftovers in the refrigerator.

Pro Tips

• Room temperature ingredients are key for the cheesecake layer. Cold cream cheese or eggs can result in a lumpy, curdled texture. Let them sit out for 30–60 minutes before starting.
• Don’t overmix the cheesecake batter. Overmixing incorporates too much air, which can cause cracking during baking. Mix just until ingredients are combined.
• Cool completely before refrigerating. If you put warm bars in the fridge, condensation can make the top soggy. Let them cool on the counter first.
• Use fresh rhubarb when possible for the best texture. Frozen rhubarb works, but it releases more liquid, so cook it a bit longer to thicken.
• Chill overnight for clean slices. The bars need time to set completely. Cutting too early can result in messy layers.
• Line the pan with parchment paper with overhang — this makes lifting the bars out much easier and keeps your pan clean.
• Don’t skip the salt in the crust and crumble. Salt enhances the sweetness and balances the tart rhubarb.
• For a neater crumble topping, freeze the butter cubes for 10 minutes before mixing with the dry ingredients. This helps create larger, distinct crumbs.
• If the crumble browns too fast, tent the pan loosely with aluminum foil for the last 10 minutes of baking.

Variations and Substitutions

• Strawberry Rhubarb Bars: Replace half the rhubarb with fresh or frozen strawberries. The strawberries add sweetness and a beautiful red color.
• Lemon Blueberry Rhubarb Bars: Add 1 tablespoon lemon zest to the cheesecake layer and swap half the rhubarb with fresh or frozen blueberries. The lemon brightens the flavors.
• Coconut Rhubarb Bars: Add ½ cup unsweetened shredded coconut to the crumble topping. Toast the coconut first for extra flavor.
• White Chocolate Rhubarb Bars: Sprinkle ½ cup white chocolate chips over the cheesecake layer before adding the rhubarb. The white chocolate pairs beautifully with the tart fruit.
• Vegan Rhubarb Cheesecake Bars: Use dairy-free cream cheese, butter, and your favorite egg substitute (flax eggs work well). The texture will be slightly different but still delicious.
• Gluten-Free Rhubarb Cheesecake Bars: Use a 1:1 gluten-free flour blend in the crust and crumble. Add ¼ teaspoon xanthan gum if your blend doesn’t include it.
• Mini Rhubarb Cheesecake Bars: Bake the bars in a muffin tin lined with paper liners. Reduce baking time to 20–25 minutes, checking for doneness.

Storage and Reheating

Fridge

Store leftover bars in an airtight container in the refrigerator for up to 5 days. Place pieces of parchment paper between layers to prevent sticking. The bars are best served cold or at room temperature.

Freezer

These bars freeze beautifully. Wrap each individually in plastic wrap, then place in a freezer-safe bag or container. They will keep for up to 3 months. Thaw in the refrigerator overnight before serving. Do not microwave to thaw, as the crust may become soggy.

Reheating

If you prefer a warm crumble, reheat individual bars in a 300°F (150°C) oven for about 10 minutes, or in the microwave on low power for 15–20 seconds. The cheesecake layer will soften, so enjoy immediately.

FAQ

Can I use frozen rhubarb without thawing? Yes, you can use frozen rhubarb straight from the bag. Do not thaw it, as thawed rhubarb releases too much liquid and can make the filling watery. Cook it directly with the sugar and cornstarch; it may take an extra 2–3 minutes to thicken.

How do I know when the bars are done baking? The edges should be set and slightly puffed, and the center should still jiggle just a little when you shake the pan — like a cheesecake. The crumble should be golden brown. Overbaking can cause the cheesecake to crack.

Can I make these bars ahead of time? Absolutely! These bars taste even better after resting in the fridge for a day. Prepare them up to 2 days in advance, cover tightly, and refrigerate. Slice just before serving.

Why did my cheesecake layer crack? Cracking can happen if the cheesecake is overbaked or if the ingredients were cold. Make sure your cream cheese and eggs are at room temperature, and avoid overmixing the batter. Also, don’t open the oven door during baking.

Can I reduce the sugar? Yes, you can reduce the sugar in the rhubarb filling to ¼ cup if you prefer a tarter dessert. For the crust and crumble, you can reduce sugar by up to 25%, but the texture may be slightly less tender.

What can I substitute for cream cheese? For a lighter version, use neufchâtel cheese or part-skim ricotta blended until smooth. For a dairy-free option, use a high-quality vegan cream cheese that bakes well.

Can I use a different pan size? An 8×8-inch pan works for thicker bars — double the crust and crumble quantities and reduce baking time by 5–10 minutes. A 9-inch square pan is also fine. Check for doneness starting at 30 minutes.

How do I get clean slices? Chill the bars for at least 4 hours (overnight is best). Use a sharp knife and wipe it clean with a damp paper towel between cuts. For extra clean edges, dip the knife in hot water and dry before slicing.
