Creamy Rhubarb Crumble Cheesecake Bars

These Creamy Rhubarb Crumble Cheesecake Bars feature a crunchy oat crust, smooth cheesecake, and tangy rhubarb topping—an easy, delicious dessert for any occasion.

Ingredients
  

For the Crust and Crumble:

  • cups all-purpose flour
  • 1 cup packed light brown sugar
  • 1 cup old-fashioned oats
  • ¾ cup unsalted butter melted
  • ½ tsp cinnamon
  • ¼ tsp salt

For the Cheesecake Layer:

  • 16 oz cream cheese softened
  • ½ cup granulated sugar
  • 2 large eggs
  • 1 tsp vanilla extract

For the Rhubarb Layer:

  • 3 cups chopped rhubarb fresh or frozen
  • ¾ cup granulated sugar
  • 1 tbsp cornstarch
  • 1 tbsp lemon juice

Instructions
 

  • Preheat oven to 350°F (175°C). Line a 9x13-inch pan with parchment or foil, leaving an overhang.
  • Mix flour, brown sugar, oats, cinnamon, and salt. Stir in melted butter until crumbly. Press two-thirds into the pan to form crust; set aside the rest.
  • Combine rhubarb, sugar, cornstarch, and lemon juice in a saucepan. Cook over medium heat, stirring until thickened (7–10 minutes). Cool slightly.
  • Beat cream cheese and sugar until smooth. Add eggs one at a time, then vanilla, mixing well.
  • Spread cheesecake over crust. Spoon rhubarb on top, then sprinkle remaining crumble.
  • Bake 40–45 minutes until golden and center jiggles slightly. Cool completely, then refrigerate at least 2 hours before slicing.
