The Ginger Rhubarb Cake You’ve Been Looking For

This recipe doesn’t use weird egg replacements and uses basic ingredients you already have in your pantry.
This is the perfect recipe to whip up under short notice since you’ll have the ingredients at home- ready to go!

What You Need

To make this vegan rhubarb cake you’ll need a cake pan- a round 9-inch pan is perfect for this! If you use another size cake pan, you’ll need to adjust your overall cook time. If you use a larger 10 inch pan the cook time will need to be reduced. If you choose to use a smaller but taller cake pan for this, you’ll need to increase the bake time.
For best results that follow this recipe try to stick with a 9-inch pan!

Since this recipe uses ginger to help give this cake balance, you’ll want to have either fresh or frozen ginger. Grate it with a micro plane grater (like a zester) to make it extra fine. Frozen ginger grates much better than fresh ginger (frozen ginger also stores much better than in the refrigerator)!

You can use either fresh or frozen rhubarb for this recipe. If you use frozen rhubarb, take it out of the freezer and allow it to fully defrost before using it. If you try to bake with frozen rhubarb, it will take much longer to cook.

This recipe calls for soy milk, but any type of plant-based milk will work.
Soy milk is recommended where it curdles unlike many other plant milks. It is also higher in protein than most milks which can help improve the cake’s overall structure. You will have a fluffier and lighter cake if you use soy milk compared to a lower protein milk like almond or oat. The protein helps the cake keep its shape as it rises, where a lower protein milk will not offer that same support leading to a denser cake. Which is still delicious- however it will feel moister and heavier.

For the crumb portion of this ginger rhubarb cake, you will need a butter. I linked in the ingredients to a plant-based butter that I like, Miyoko’s. You can use any brand of butter you prefer! I’ve also had good results with Earth Balance. Flavor wise I prefer Miyoko’s, but Earth Balance is a great budget option. (I’m not sponsored in any way; these are my opinions!)

How to Make a Rhubarb Cake with No Eggs

This cake recipe is very simple! The best part is that is made with simple ingredients that most kitchens will have.

To start you’ll add mix your dry ingredients in a medium sized bowl. Using a sifter is ideal to ensure there are no clumps and everything mixes together correctly. A fine mesh strainer works great as a sifter! Another way to help prevent clumps is to mix the dry ingredients with a whisk.

Then a large bowl you’ll mix together all the wet ingredients- including the grated ginger. You don’t need a stand mixer for this, a quick stir to incorporate everything is all you need.

From there you’ll add the dry ingredients to the wet ingredients to create batter. Once everything is stirred together you’ll add in the chopped rhubarb and then pour everything into you cake pan.

Once everything is in the cake pan you’ll start making the crumble topping. You’ll mash cold butter with a fork into the flour sugar mixture with minced rhubarb. You need the rhubarb to be minced into small pieces so it can mix in with the flour sugar mixture.
From there you’ll evenly sprinkle the mixture over the cake. Don’t worry if you have too big of clumps over the top- it’ll all melt into the cake.
