Ingredients
Method
Preheat oven to 350°F. Line an 8x8-inch baking pan with parchment paper.
Mix oats, flour, brown sugar, cinnamon, and melted butter until crumbly. Press firmly into the prepared pan.
Bake the crust for 12 minutes, then remove and cool slightly.
Beat cream cheese, sugar, egg, and vanilla until smooth. Spread evenly over the crust.
In a bowl, toss rhubarb with sugar, cornstarch, and lemon juice until coated.
Spoon the rhubarb mixture evenly over the cheesecake layer.
Bake for 30 to 33 minutes, or until the cheesecake is mostly set and the rhubarb is tender.
Cool completely at room temperature.
Refrigerate for at least 3 hours before lifting from the pan and slicing into bars.
Notes
Store covered in the refrigerator for up to 5 days. Frozen rhubarb can be used if thawed and drained well. For cleaner slices, chill overnight before cutting. These bars freeze well for up to 2 months.
