Recipe ingredients
Rhubarb: The rhubarb season starts in April and ends sometime in June, so if you want to make this rhubarb meringue cake, now is the time.
- Use fresh rhubarb stalks from the garden or the supermarket (discard the leaves; they are poisonous). Don't peel the stalks; just clean them properly and remove the lower whitish part.
- If you have lots of rhubarb, check out these Rhubarb Recipes.
Granulated sugar is used in different parts of the rhubarb meringue cake. It is used to steep the rhubarb pieces and remove the excess liquid, it sweetens the cake base, and it's beaten with the egg whites to create the meringue.
Eggs: You will need four eggs for the batter and four egg whites for the topping.
Other ingredients: Butter, flour, baking powder, vanilla extract, milk, and a little vinegar.
See the recipe card for full information on ingredients and quantities.
How to make rhubarb meringue cake?
- Step #1: Cut the stalks into slices about as thick as your finger. Mix the pieces with 2 tablespoons of sugar and place them in a colander. Drain for about 30 minutes. This step helps remove the excess moisture and prevents the cake base from getting soggy.
- Step #2: Beat sugar and soft butter in a large mixing bowl until fluffy. Scrape.
- Step #3: Add the eggs, one at a time, and then add vanilla extract and salt. Scrape.
- Step #4: Mix flour and baking powder in a separate bowl. Incorporate half of the flour mixture and then half of the milk into the egg mixture.
- Step #5: Add the remaining flour, incorporate, add the remaining milk, and mix again on low speed. Scrape.
- Step #6: Pour the batter into the prepared baking dish. Pat the rhubarb slices dry with paper towels and arrange them on top of the batter.
- Step #7: Bake in the preheated oven for about 40 minutes.
- Prepare the topping during the last 10 minutes of the cake's baking time.
- Step #8: Beat the egg whites on high speed until they begin to foam. Then, add salt and vinegar and continue beating until soft peaks start to form.
- Step #9: Start adding the sugar gradually. Continue beating until the meringue is stiff and glossy.
- Step #10: Spread the meringue evenly over the cake, and return the rhubarb cake to the oven.
- Step #11: Bake it for another 10 to 15 minutes or until the meringue is golden (the exact time depends on your oven). Let the cake cool completely before you slice it.
Tips
Most important tip: Always use a digital kitchen scale in baking; it guarantees the best results.
Beating egg whites: Make sure the bowl and the beaters you are using are perfectly clean and dry; any trace of fat will prevent the egg whites from stiffening.
Avoid overbeating the meringue: Stop beating it once it reaches stiff peaks. Overbeating can cause the meringue to become grainy and lose its smooth texture.

Storage
Make in advance: You can make it one day in advance. Let it cool completely in the pan, then cover it with a large, clean kitchen towel. Leave it at room temperature (not too warm) until the next day.
If the weather is hot, refrigerate the cake.
Store it in an airtight container at room temperature for 1-2 days.
To keep it longer, refrigerate it in an airtight container; this way, it will last 3-4 days. Let it come to room temperature before serving it again.
Meringue doesn't freeze well.

Notes
- Scale: Always use a digital kitchen scale in baking; it guarantees the best results(the Amazon affiliate link opens in a new tab).
- Egg size: If you live in Germany (where this kind of cake is very popular), please use medium eggs.
- Again, I strongly recommend using a scale to measure the flour and the butter. I measured the 400 g in cups and had 3 cups of flour, but that result can easily differ from one person to another. If you google it, google will tell you that 400 g is 3.2 cups of flour.
- Egg whites: Use a very clean bowl and beaters for making the meringue; any trace of fat will prevent the egg whites from stiffening.

What a great sounding cake! My parents used to grow a patch of rhubarb every year and my father would make strawberry rhubarb pie. I'm sure it was more of a joint effort between mom and dad because I can't see my dad rolling a pie crust! I laugh to think of it. But, I love the tartness rhubarb and can only imagine how well it plays with the sweet meringue. Stunning photos as always.

Yummy! I want to make this cake again, but I don't know if I can find rhubarb so easily during this time of year. I was amazed to even find it this spring. I wonder what it would taste like with apricots. 🙂
