Ingredients for Rhubarb Cake Recipe
Rhubarb: A tart vegetable often used in desserts, providing a unique flavor and texture to the cake.
Sugar: Sweetens the cake and balances the tartness of the rhubarb.
Butter: Adds richness and moisture to the cake, ensuring a tender crumb.
Vanilla extract: Enhances the overall flavor with a warm, sweet aroma.
Eggs: Provide structure and stability to the cake batter.
All-purpose flour: The main dry ingredient that forms the base of the cake.

Technique Tip for This Recipe
When creaming together the butter and sugar, ensure the butter is at room temperature. This will help achieve a light and fluffy texture, which is crucial for the overall cake consistency. Additionally, when folding in the rhubarb, do so gently to avoid breaking down the pieces, ensuring they are evenly distributed throughout the batter.
