Step-by-Step Instructions

Preheat your oven
- Set the oven to 350°F (175°C).
- Grease a 9×13-inch baking dish or line it with parchment paper for easy removal.
Prepare the crust and crumble mixture
- In a large mixing bowl, combine:
  - 1 1/2 cups all-purpose flour
  - 1 1/2 cups old-fashioned oats
  - 1 cup packed brown sugar
  - 3/4 cup melted unsalted butter
- Mix until well combined and crumbly.
- Fold in 1/2 cup chopped nuts if using.
- Set aside 1 1/2 cups of this mixture for the crumble topping.
Form and bake the crust
- Press the remaining mixture firmly into the bottom of your prepared baking dish.
- Use your hands or the flat bottom of a measuring cup to even it out.
- Bake for 10 minutes, then remove from oven and let cool slightly.
Make the cream cheese layer
- In a medium bowl, beat together:
  - 8 oz softened cream cheese
  - 1/2 cup granulated sugar
  - 1 large egg
  - 1 tsp vanilla extract
- Beat until the mixture is smooth and creamy with no lumps.
- Pour the cream cheese filling over the cooled crust and spread evenly using a spatula.

Cook the rhubarb filling
- In a medium saucepan, combine:
  - 3 cups diced rhubarb
  - 1 cup granulated sugar
  - 1/4 cup cornstarch
  - 1/4 cup water
- Cook over medium heat, stirring constantly.
- Continue cooking for about 8–10 minutes, until the mixture thickens and the rhubarb softens and breaks down.
- Remove from heat and allow to cool for 5–10 minutes.
Assemble the bars
- Gently spoon the cooled rhubarb filling over the cream cheese layer.
- Spread evenly with the back of a spoon or an offset spatula.
- Sprinkle the reserved 1 1/2 cups of crumble mixture over the top.
Bake the assembled bars
- Return the baking dish to the oven.
- Bake for 30–35 minutes, until the crumble topping is golden brown and the center is mostly set.
Cool and chill before slicing
- Let the bars cool completely at room temperature.
- Once cooled, refrigerate for at least 2 hours to allow the layers to firm up.
- Cut into squares and serve.

Serving and Storage Tips

Serve chilled or at room temperature for a firmer texture and refreshing bite.
Perfect with coffee or tea, or add a dollop of whipped cream or scoop of vanilla ice cream.
Store in the fridge in an airtight container for up to 5 days.

To freeze, wrap individual bars tightly in plastic wrap, then place in a freezer-safe container or bag. They’ll last up to 3 months.
Thaw overnight in the fridge or microwave for 15–20 seconds before enjoying.

Helpful Notes

Don’t overbake: The bars will continue to firm up as they cool.

Use full-fat cream cheese for the best creamy consistency.
Fresh or frozen rhubarb works—just chop uniformly for even cooking.
Strawberry variation: Replace 1 cup of rhubarb with diced strawberries.
Gluten-free option: Use a 1:1 gluten-free flour blend and gluten-free oats.

Nut-free version: Simply leave out the nuts for an allergy-friendly treat.

Frequently Asked Questions

Can I freeze Creamy Rhubarb Cream Cheese Bars?
Yes, these bars freeze very well. Once completely cooled and cut, wrap each bar individually in plastic wrap and store in a freezer-safe container or bag. To serve, thaw in the fridge overnight or let sit at room temperature for 30 minutes.
What if I don’t have fresh rhubarb?
No problem! Frozen rhubarb is a great substitute. You don’t need to thaw it before cooking—just increase the cooking time slightly and monitor for doneness.

Can I make this recipe ahead of time?
Absolutely. These bars are actually better after sitting overnight in the fridge. The flavors meld beautifully, and the layers become more cohesive and easier to slice.
Can I use quick oats instead of old-fashioned oats?
Yes, quick oats can be used in a pinch. However, they will give the crust and topping a softer, less textured feel compared to old-fashioned oats.
How do I know when the bars are done baking?
Look for a golden brown topping and a center that no longer jiggles when gently shaken. A slight puffiness in the cream cheese layer is normal and will settle as it cools.
