Ingredient Breakdown
For the Rhubarb Layer
- Fresh Rhubarb (3 cups, chopped):
The star of the show. Rhubarb’s natural tartness gives the dessert a bright, fruity flavor and vibrant pink color. It’s a healthy ingredient rich in antioxidants and vitamin K a great way to add real fruit flavor to your dessert. - Granulated Sugar (1¼ cups):
Balances the tartness of the rhubarb and creates that irresistible sweet-tart compote. You can adjust the sugar level depending on how tangy you prefer your dessert. - Cornstarch (2 tbsp):
The secret to achieving a luscious, jam-like consistency. It thickens the rhubarb mixture so it holds its shape when layered over the creamy filling. - Water (¼ cup):
Helps the rhubarb cook evenly and prevents burning while dissolving the cornstarch smoothly. - Lemon Juice (1 tbsp):
Adds a burst of acidity and enhances the natural fruit flavor, creating a more vibrant and refreshing taste.
For the Cream Layer
- Cream Cheese (8 oz, softened):
The creamy backbone of the dessert rich, tangy, and perfectly smooth. Cream cheese gives structure and depth to the filling, making each bite velvety and satisfying. - Powdered Sugar (1 cup):
Sweetens without graininess and blends easily with the cream cheese. It ensures the filling remains silky and light. - Heavy Whipping Cream (1 cup):
Whipped to stiff peaks, it transforms the filling into a light, airy mousse that contrasts beautifully with the dense rhubarb layer. - Vanilla Extract (1 tsp):
Adds warmth and a subtle sweetness that ties the whole dessert together. Always use pure vanilla extract for the best flavor.
For the Crust
- Graham Cracker Crumbs (1½ cups):
The foundation of the dessert crisp, buttery, and slightly sweet. It adds the perfect texture and holds the layers together. - Granulated Sugar (¼ cup):
Helps bind the crumbs and adds a touch of sweetness to balance the tart rhubarb. - Ground Cinnamon (½ tsp):
A cozy spice that enhances the flavor profile with warmth and depth. It pairs beautifully with the fruity filling. - Unsalted Butter (¼ cup, melted):
Acts as the glue for the crust, giving it a rich, buttery flavor and firm texture once chilled.

Rhubarb Icebox Dessert
Ingredients
Method
- Step 1: In a medium saucepan, combine rhubarb, sugar, cornstarch, water, and lemon juice. Cook over medium heat, stirring often, until the mixture thickens and the rhubarb softens (about 10–12 minutes). Set aside to cool completely.
- Step 2: In a bowl, mix graham cracker crumbs, sugar, cinnamon, and melted butter until evenly combined. Press the mixture firmly into the bottom of a 9×9-inch baking dish. Chill in the refrigerator while preparing the cream layer.
- Step 3: In a large mixing bowl, beat softened cream cheese and powdered sugar until smooth and creamy. In a separate bowl, whip the heavy cream and vanilla extract until stiff peaks form. Gently fold the whipped cream into the cream cheese mixture until light and fluffy.
- Step 4: Spread the cream layer evenly over the chilled crust. Spoon the cooled rhubarb mixture over the top and spread it gently to cover.
- Step 5: Cover and chill the dessert for at least 3 hours, or until set. Slice into squares and serve cold.
