Step‑by‑Step Instructions for Rhubarb Fluff
Step 1: Prepare the Base
In a mixing bowl, combine all-purpose flour, margarine, and granulated sugar until crumbly. Press this mixture evenly into a greased 9×13-inch baking pan, ensuring it forms a solid layer. Bake in a preheated oven at 350°F (175°C) for about 10 minutes, or until the edges turn golden brown. Once out of the oven, let the crust cool completely while you prepare the rhubarb filling.
Step 2: Prepare the Rhubarb
Chop the rhubarb into small pieces and place them in a bowl. Pour boiling water over the chopped rhubarb, allowing it to soften for about 10 minutes. After steeping, drain any excess water from the rhubarb to prevent it from becoming too soggy. This juicy tangy rhubarb will serve as the delightful layer for your Rhubarb Fluff.
Step 3: Layer the Rhubarb
Once the crust has cooled, evenly spread the softened rhubarb over the top, making sure to cover the entire surface. The tangy rhubarb not only adds flavor but also creates a vibrant visual appeal. This layer will contrast beautifully with the rich filling you’re about to make, setting the stage for a delicious Rhubarb Fluff.
Step 4: Make the Filling
In a separate mixing bowl, whisk together egg yolks, granulated sugar, and a pinch of salt until well combined. Gradually mix in the milk and a bit of flour, stirring until the mixture is smooth and free of lumps. Carefully pour the filling over the rhubarb layer in the pan, and place it in the oven to bake for approximately 40 minutes at 350°F (175°C) until set and slightly puffed.
Step 5: Whip Up the Meringue
In a clean mixing bowl, beat the egg whites with cream of tartar at high speed until stiff peaks form. Gradually add sugar while continuing to beat, creating a glossy meringue that holds peaks. This fluffy cloud-like meringue will be the crowning glory of your Rhubarb Fluff, adding sweetness and lightness that perfectly balances the tartness of the rhubarb.
Step 6: Top with Meringue
Once the filling is baked and has a slight jiggle, gently spread the whipped meringue over the filling, being careful to cover it completely. Create swirls or peaks for visual appeal. Return the pan to the oven and bake for an additional 10 minutes, or until the meringue is golden brown and puffy, resembling a beautiful cloud atop your Rhubarb Fluff.
Step 7: Cool and Serve
After baking, remove the Rhubarb Fluff from the oven and allow it to cool completely in the pan on a wire rack. Once cooled, cut it into squares and serve. The contrast of the buttery crust, tangy filling, and fluffy meringue will surely delight your friends and family at any spring gathering!

Rhubarb Fluff Recipe FAQs
What type of rhubarb should I use for Rhubarb Fluff?
