- 2 cups Graham Crackers (Substitute with gluten-free if needed.)
- 1/2 cup Butter (Use vegan butter for a dairy-free version.)
- 4 cups Rhubarb (Fresh rhubarb is preferred; use frozen if fully thawed and drained.)
- 1 cup Sugar (Adjust based on rhubarb’s tartness.)
- 2 tablespoons Cornstarch (Can replace with tapioca starch if desired.)
- 1/2 cup Water
- 1 teaspoon Vanilla Extract (Use pure vanilla for best flavor.)
- 2 cups Heavy Cream (Can use coconut cream for dairy-free option.)
- 1 cup Mini Marshmallows (Jet-Puffed miniatures work best.)
- 1 package Vanilla Pudding (Prepared according to package instructions.)

Directions
Start by crushing the graham crackers into fine crumbs. You can use a food processor or place them in a ziplock bag and crush with a rolling pin.
In a medium saucepan, melt the butter over low heat. Once melted, add the crushed graham crackers and stir until well combined.
Press the graham cracker mixture into the bottom of a 9×13 inch dish to form a crust layer.
In the same saucepan, mix the rhubarb, sugar, cornstarch, and water. Cook over medium heat, stirring often, until the mixture thickens and the rhubarb softens.
Once the rhubarb mixture is ready, pour it over the crust and spread it evenly.
In a separate bowl, whip the heavy cream until soft peaks form. Fold in the mini marshmallows and vanilla pudding gently.
Spread the creamy mixture over the rhubarb layer, smoothing it out evenly.
Refrigerate the bars for at least 4 hours or until set.
Serving
Once the bars are set, cut them into squares and serve chilled. They pair beautifully with fresh fruit or a drizzle of caramel sauce. If you’re looking for more easy summer treats, consider making lazy s’mores cookie bars for a fun twist on a classic flavor!
