Spring is the perfect time to make a dish that’s both bright and comforting and this Rhubarb Fluff recipe nails it. Its creamy texture pairs with tangy rhubarb to wow guests at brunches and holiday tables alike. I reach for this recipe anytime I want to highlight rhubarb’s unique flavor in a creamy dreamy bite that vanishes fast.
This recipe quickly became a family favorite after I made it for our Mother’s Day picnic. Now even my skeptical brother asks for it by name each spring.
Ingredients
- All purpose flour: It creates a crisp sturdy base for the layers Quality flour gives the best bite
- Margarine: Makes the base buttery and soft Choose a high quality margarine for best texture
- Granulated sugar: Lends sweetness throughout Use pure white sugar for a clean flavor
- Chopped rhubarb: Brings tartness and color Go for fresh stalks that are deeply red with no brown spots
- Egg yolks: Thickens and enriches the filling Fresh yolks add flavor and creaminess
- Milk: Helps the filling become smooth and gentle Whole milk gives the best richness
- Egg whites: The star of the meringue Select eggs with the freshest whites for perfect peaks
- Cream of tartar: Stabilizes your meringue Look for a fine powder
- Salt: Balances out the sweetness Only a hint is needed
- Coconut: Optional for the top Use unsweetened and shred it finely for best texture
Step-by-Step Instructions
- Prepare the Base:
- Mix flour margarine and sugar just until combined so the dough is crumbly and even. Press firmly into a greased nine by thirteen inch pan. Level the surface for even baking.
- Bake the Base:
- Heat oven to three hundred fifty degrees Fahrenheit. Bake the crust for ten minutes so it sets but does not brown. Remove from oven and let cool for at least ten minutes before adding filling.
- Prepare the Rhubarb:
- Place chopped rhubarb in a large bowl and cover with boiling water. Let it soak for ten minutes to soften the fibers. Drain thoroughly by pressing out extra liquid with a towel.
- Layer the Rhubarb:
- Spread the prepared rhubarb evenly over the cooled base pressing lightly to create a uniform layer. Make sure the pieces are distributed edge to edge.
- Make the Filling:
- In a new bowl whisk together egg yolks sugar and salt until pale and well blended. Gradually whisk in flour then slowly pour in milk stirring continuously until the mixture is completely smooth.
- Add the Filling and Bake:
- Pour filling evenly over the rhubarb layer letting it seep between the pieces. Bake for forty minutes until the center is just set and topping looks creamy and stable.
- Whip Up the Meringue:
- Start beating egg whites with the cream of tartar at medium speed. Increase to high and keep beating until you see stiff shiny peaks. Gradually blend in sugar to make a glossy meringue that holds its shape.
- Top with Meringue and Bake Again:
- Carefully spoon the meringue onto the hot filling spreading it from edge to edge and swirling into peaks. Return to oven for ten minutes or until the top is golden and lightly toasted.
- Optional Finishing Touches:
- If desired sprinkle coconut over the meringue before final baking. This helps create extra texture and prevent any moisture on top.
- Cool and Serve:
- Let the finished dessert cool in the pan completely so layers firm up and slices stay neat when cut. Slice into squares with a sharp knife and serve at room temperature for the fluffiest bite.

Rhubarb is my springtime obsession and I have clear memories of walking with my grandmother to pick the first ruby red stalks from her garden They always ended up in this exact dessert and that ritual made it feel so special
Storage Tips
Store leftover rhubarb fluff in a covered container in the fridge for up to three days. For best texture place wax paper between layers if stacking. If you want to freeze leftovers wrap tightly in plastic and place them in a freezer bag but thaw slowly in the fridge for the best results. Meringue may lose a little volume after freezing but the taste stays lovely.
Ingredient Substitutions
If you prefer a richer base swap in real butter for margarine but keep it cold. Do not have fresh rhubarb Try frozen rhubarb but let it thaw and drain extra moisture before use. You can replace all purpose flour with a one to one gluten free blend for an allergy friendly version. If coconut is not your style leave it off or sprinkle finely chopped nuts instead.
Serving Suggestions
This dessert works beautifully after light spring meals or as a standout brunch treat. I like to cut it into smaller squares and serve with strawberries or a tiny spoonful of whipped cream. For a festive touch pile edible flowers or lemon zest curls on top.
Cultural or Historical Tidbits
Rhubarb has a long tradition in home baking going back centuries in cool climates. Its natural tartness made it a favorite for pies and puddings in the spring before berries arrived. Pairing rhubarb with meringue is a nod to classic British and German desserts where fluffy toppings balance the tang.
