Step‑by‑Step Instructions for Rhubarb Fluff Recipe
Step 1: Prepare the Base
In a mixing bowl, combine all-purpose flour, margarine, and granulated sugar using a pastry cutter or fork until crumbly. Press this mixture firmly into the bottom of a greased 9x13-inch pan, creating an even layer. This crust will form the delicious base of your Rhubarb Fluff, providing a sturdy support for the creamy filling.
Step 2: Bake Base
Preheat your oven to 350°F (175°C) and place the pan in the oven once the temperature is reached. Bake the crust for about 10 minutes until it’s golden and slightly firm. Keep an eye on it for visual cues; it should look lightly browned around the edges. After baking, remove it from the oven and let it cool completely.
Step 3: Prepare Rhubarb
In a large saucepan, bring water to a rolling boil and add the chopped rhubarb. Let it boil for approximately 10 minutes until softened. This process will extract its wonderful tart flavor. After boiling, drain the rhubarb to discard excess water and cool it slightly before adding it to the crust.
Step 4: Layer Rhubarb
Once the rhubarb has cooled, spread it evenly over the cooled crust in the pan. Make sure to distribute the rhubarb in a single layer for uniform flavor throughout your Rhubarb Fluff. The vibrant tang of the rhubarb will shine through as a delicious filling.
Step 5: Make Filling
In a separate bowl, whisk together the egg yolks, granulated sugar, salt, milk, and a bit of flour until the mixture is smooth and well combined. This rich filling will enhance the flavor profile of your dessert as it bakes, balancing the tartness of the rhubarb with sweetness. Pour this mixture over the layered rhubarb.
Step 6: Bake Filling
Return the pan to the preheated oven and bake for approximately 40 minutes. You'll know the filling is ready when it is set and slightly jiggles in the center. The edges should be lightly golden, indicating that the Rhubarb Fluff filling has developed a lovely texture.
Step 7: Whip Meringue
While the filling bakes, prepare the meringue by beating the egg whites with cream of tartar in a clean, dry mixing bowl. Beat until stiff peaks form, which should take about 5 minutes. Gradually add in sugar, continuing to beat until the meringue is glossy and holds its shape, creating a beautiful topping for the Rhubarb Fluff.
Step 8: Top and Bake Again
Once the filling is done, remove it from the oven and gently spread the meringue over the top using a spatula. Make sure to cover the filling completely. Return it to the oven and bake for an additional 10 minutes until the meringue turns a lovely golden color on top, offering a beautiful contrast to the filling beneath.
Step 9: Cool and Serve
After baking, take the Rhubarb Fluff out of the oven and allow it to cool completely in the pan. This will help set the layers and make it easier to slice. Once cooled, cut into squares and serve as a delightful spring treat that everyone will love!

Rhubarb Fluff Recipe FAQs
What is the best way to select rhubarb?

What if my meringue doesn’t hold its shape?
Don't worry! If your meringue isn’t holding its shape, it may be due to not beating the egg whites to stiff peaks or perhaps there was some grease on your mixing bowl.
