If you love desserts that strike the perfect balance between sweet, creamy, and just a little bit tangy, these Rhubarb Cheesecake Bars with Crumble Topping are about to become your new favorite!

Creamy Cheesecake Meets Bright, Tangy Rhubarb!

I recently spent time with my ever so adorable niece, Leah. I love her to pieces! She is a cheerleader in training so she randomly bursts out into her current cheer routine. It’s so great!

When we got home from our vacation together, I was overwhelmed and exhausted. My mind was set on putting my life back to normal as fast as I could, so I enabled ‘tornado mode’ and swirled about the house in a frenzy putting things away and starting laundry.

All of us pitched in to help because we wanted to get to the pool as soon as possible. Toward the end of getting everything done, I was getting crabby and moving slow.

From that moment on, I nicknamed her ‘team spirit.’ She is a natural cheerleader, a positive thinker, motivator, and encourager. I want to be just like her when I grow up!!

Why this Recipe Works

Three Distinct Textures in Every Bite – You get a buttery crumb, creamy filling, and jammy fruit layer, creating a satisfying contrast.

Dual-Purpose Crumble Mixture – The same mixture acts as both the crust and topping, ensuring consistent flavor and saving time.

Make Ahead Friendly – These bars actually improve after chilling, allowing flavors to meld and texture to set perfectly.

Balanced Flavor – Brown sugar, butter, and vanilla adds warmth that complements the tartness of the rhubarb.

How to Make Rhubarb Cheesecake Bars

Preheat oven to 350 degrees. Spray 9 x 13 pan and set aside.

Make the crust and topping by combining 1 1/2 cups flour, 1 1/2 cups old fashioned rolled oats, 1 cup brown sugar, 1/2 cup chopped pecans, and 3/4 cup melted butter with a fork.

Reserve 1 1/2 cups for the crust and set aside.

Press the remaining mixture into the prepared pan evenly. Bake for 10 minutes. Remove from oven and let cool slightly.

In a medium size bowl, beat together 1 (8 oz) softened cream cheese, 1/2 cup sugar, 1 egg, and 1 tsp vanilla until smooth and creamy.

Spread evenly over slightly cooled crust.

Cook 3 cups chopped rhubarb, 1 cup sugar, 1/4 cup corn starch, and 1/4 cup water over medium heat for 8-10 minutes. Stir frequently.

If the rhubarb sauce is too thick to spread, add enough hot water to reach spread consistency. Let cool.

Once cooled, spread over cream cheese mixture.

Sprinkle reserved crumble topping over the rhubarb sauce.

Bake for 30-35 minutes.

Let cool. Refrigerate until firm.

Use Old-Fashioned Oats (Not Quick Oats) – Keeps the texture hearty and not mushy.

Flavor Boost – Add cinnamon to the crumble for warmth.
