Is this rhubarb cake easy to make?
You will see from the instructions, I tell you to throw all your cake ingredients into a bowl and simply mix them all together. You read that right! So no creaming and folding in the flour, or sieving. Just the whole lot, into a bowl and grab a handheld mixer or wooden spoon and mix everything together until combined.
What does rhubarb cake taste like?
This rhubarb cake is a wonderfully moist and soft cake in texture. The flavor is a mix of sharpness from the rhubarb and sweetness from the streusel topping. Combined with a sprinkle of cinnamon and ginger in the topping, the flavor combination is simply wonderful.
The cake isn't overly sweet. It's got a nice tangy zingy kick to it from the rhubarb. If you do prefer a very sweet cake, increase the sugar by another ¼ of a cup.
When you take a bite with the sweet streusel topping, that has the added sweetness which I think is just right, but everyone has a certain sweetness they prefer.

How to serve rhubarb cake
This cake would be perfect to serve as a breakfast time cake, or for afternoon tea or as a snack. You can serve it warm with a pouring of delicious custard, or a blob of whipped cream. Or just eat it as it is, with a nice cup of tea or coffee.
This has definitely become my new favorite recipe! Firstly because it's such a simple cake to make, the ingredients are usually in your pantry, and ultimately, the flavor is absolutely out of this world.
When I first baked it, I let it cool so it was just warm to touch, and then had a slice. Oh my! Actually, I ended up having 2 slices. It is really good!
We've also got a really easy Homemade Strawberry Cake so make sure you make that too!
Can you use frozen rhubarb in a cake?
The simple answer is no. This cake is moist as it is, and if you use frozen rhubarb, the added liquid will turn your cake quite mushy. The same applies to canned rhubarb.
Unless you were prepared to play around with the ingredient ratios, for the flour and eggs in particular, in my opinion, I think there will be too much liquid for the cake to turn out just right.
So we're going to see how easy it is to make rhubarb cake from scratch. Just follow the step by step simple instructions and you can't go wrong. Please enjoy!
