Step‑by‑Step Instructions for Rhubarb Fluff Recipe
Step 1: Prepare the Base
In a large mixing bowl, combine all-purpose flour, margarine, and granulated sugar until crumbly. Press this mixture firmly into a greased 9×13-inch pan, ensuring an even layer. Create a smooth surface with your fingers or a spatula to form the crust, setting the stage for the delightful Rhubarb Fluff.
Step 2: Bake the Base
Preheat your oven to 350°F (175°C). Place the crust in the oven and bake for about 10 minutes, or until it turns a light golden brown. Once done, remove it from the oven and allow the crust to cool completely in the pan, creating a sturdy foundation for your filling.
Step 3: Prepare the Rhubarb
While the crust cools, bring a pot of water to boil. Add the chopped rhubarb and let it soak in the boiling water for approximately 10 minutes, which will soften it and enhance its tart flavor. After soaking, thoroughly drain the rhubarb and set it aside, ready to layer on top of the crust.
Step 4: Layer the Rhubarb
Once the crust is cool, spread the softened rhubarb evenly over the surface with a spatula. This layer will provide a vibrant tartness that perfectly balances the sweetness of the filling. Ensure the rhubarb covers the crust completely, preparing it for the silky filling of your Rhubarb Fluff.
Step 5: Make the Filling
In a clean mixing bowl, whisk together the egg yolks, granulated sugar, salt, milk, and a bit of flour until smooth and well-combined. This rich mixture will create a creamy filling that binds all the layers together. Carefully pour the filling over the rhubarb layer, allowing it to settle.
Step 6: Bake Filling
Place the pan back in the oven and bake for about 40 minutes, or until the filling is set and firm to the touch. You’ll know it’s done when the edges are slightly puffed and the center has a slight jiggle. This is the foundation of your delightful Rhubarb Fluff.
Step 7: Whip Meringue
While the filling bakes, prepare the meringue. In a clean mixing bowl, beat the egg whites with cream of tartar until stiff peaks form, which will take about 4-5 minutes. Gradually add granulated sugar and continue beating until the mixture is glossy. It should hold its shape beautifully.
Step 8: Top with Meringue
Once the filling is done baking and slightly cooled, spread the whipped meringue generously over the top. Use a spatula to create peaks and swirls for a beautiful finish. Return the pan to the oven and bake for another 10 minutes or until the meringue is golden brown and slightly toasted.
Step 9: Cool and Serve
Remove the Rhubarb Fluff from the oven and allow it to cool completely at room temperature. Once cooled, slice into squares with a sharp knife and serve. This delightful dessert is now ready to impress your family and friends with its stunning layers and delectable flavors!

Rhubarb Fluff Recipe FAQs
What should I look for when selecting rhubarb?
Absolutely! When picking rhubarb, look for firm stalks that are crisp and have a vibrant color—red or green, depending on the variety. Avoid stalks that are limp or have dark spots all over. If you can, feel the weight; heavier stalks often have a sweeter flavor!
How should I store leftover Rhubarb Fluff?
To keep your Rhubarb Fluff fresh, store it in an airtight container in the fridge for up to 3 days. Before serving, let it sit at room temperature for 10-15 minutes to soften the textures. This allows the creamy filling to regain its silky consistency, making it delightful to enjoy!
Can I freeze Rhubarb Fluff, and if so, how?
Absolutely! To freeze your Rhubarb Fluff, slice it into individual portions. Wrap each slice tightly in plastic wrap or aluminum foil, then place them in a freezer-safe bag. It can be stored in the freezer for up to 2 months. When ready to enjoy, simply reheat in a preheated oven at 350°F (175°C) for about 10-15 minutes until warm!
What can I do if my meringue doesn’t form stiff peaks?
No worries! If your meringue is not forming stiff peaks, make sure your mixing bowl and beaters are perfectly clean and dry—any grease can hinder the process. If you’re still having trouble, try adding a pinch more cream of tartar, which helps stabilize the meringue. Beat until glossy peaks form, and remember, patience is key!

Very! This Rhubarb Fluff recipe can easily be adapted to meet various dietary needs. For a gluten-free option, simply use gluten-free flour for the crust.
