Whether you're serving it at a family gathering or enjoying a slice with your afternoon tea, this cake is sure to impress.
Rhubarb might not be a staple in every household, but it is worth seeking out for this recipe. Look for fresh, firm stalks with a vibrant red color at your local supermarket or farmer's market.

You can usually find it in the dairy section of your grocery store.

Technique Tip for Rhubarb Cake
When creaming together the butter and sugar, ensure the butter is softened but not melted. This will help incorporate air into the mixture, resulting in a lighter and fluffier cake. Use a stand mixer or hand mixer on medium speed for about 3-5 minutes until the mixture is pale and creamy.
