These Rhubarb Cheesecake Squares are the kind of spring dessert I crave as soon as rhubarb starts popping up at the market. The layers of tender oat crust and creamy spiced filling make every bite feel like a cozy celebration. I love making these a day in advance and cutting them into tidy squares once chilled. They are always the first treat to disappear at gatherings.

I first made this recipe for a Mother’s Day brunch and it was such a hit that it has become a yearly tradition. My sister even requests I bring a batch every time we visit.

Ingredient Substitutions

If you do not have rhubarb try using fresh or frozen strawberries or raspberries. A half and half blend also works beautifully. You can use quick oats in a pinch but the texture will be slightly softer.

Serving Suggestions

Serve these squares with a dollop of whipped cream or a scoop of vanilla ice cream. They pair wonderfully with hot tea or coffee and make a lovely addition to spring brunch tables or afternoon dessert platters.
