What is Rhubarb Cake?
This moist Rhubarb Cake recipe is a light and tender morning tea-style cake, filled with pieces of fresh rhubarb that give it a super satisfying burst of tang with nearly every bite. It takes only minutes to throw together, and can be eaten for dessert or even breakfast (well, in my house it is, anyway).
Rhubarb Cake Ingredients
This cake combines the usual cake ingredients with rhubarb and sour cream. Sour cream helps keep this cake perfectly moist and also blends well with tangy rhubarb. For the cake itself, you’ll need:
- Baking powder
- Brown sugar
- Lemon zest
- Sour cream
For the streusel topping, you’ll need:
- Turbinado sugar
RECIPE TIP: You can substitute fresh for frozen rhubarb in this cake; however, don’t thaw it before you add it to the batter.
How to make Rhubarb Cake
Follow these simple instructions to make a rhubarb cake:
- First, beat butter and sugar together until the mixture is light and creamy, then add vanilla and lemon zest followed by the eggs one at a time, beating well after each addition.
- Add half the flour and baking powder and mix, followed by the sour cream, mix, then add the remaining flour mixture.
- Next, add in the chopped rhubarb and fold the batter, just until everything is combined.
- After tipping this into a spring-form tin, the final step is to top the cake with a mixture of flaked almonds, turbinado sugar, and cinnamon, for a satisfying crunch on top.
