Key Ingredients in Omas Rhubarb Cake

Rhubarb: A Tart Delight

Rhubarb, known for its tart flavor, is the star ingredient in Oma’s Rhubarb Cake. Its bright red stalks add a unique sourness that balances the cake’s sweetness. Ensure you use fresh, firm rhubarb, free from blemishes. Cut the stalks into small pieces, about 1-inch long, to distribute the tartness evenly throughout the cake.

Supporting Ingredients for Balanced Flavor

Other essential components complement the rhubarb, creating a harmonious flavor profile.

  • Flour: Provides structure. Use all-purpose flour for optimal texture and consistency.
  • Sugar: Sweetens the cake. Granulated sugar works best; adjust the quantity to balance the tartness of the rhubarb.
  • Eggs: Bind the ingredients. Use fresh, large eggs for best results.
  • Butter: Adds richness. Opt for unsalted butter to control the cake’s salt content.
  • Baking Powder: Ensures the cake rises. Ensure it’s fresh for effective leavening.
  • Milk: Moistens the batter. Whole milk offers the best flavor and texture.

Step-by-Step Recipe for Omas Rhubarb Cake

Preparing the Rhubarb

Start by selecting fresh rhubarb stalks. Wash them thoroughly under running water. Trim the ends and peel any tough outer strings if present. Cut the rhubarb into 1-inch pieces to ensure even baking. Place the pieces in a bowl and sprinkle with a tablespoon of granulated sugar to balance the tartness. Let them sit for at least 15 minutes. This prepares the rhubarb for incorporation into the batter.

Creating the Batter

Begin by preheating your oven to 350°F (175°C). Grease and flour a 9×13-inch baking dish. In a medium bowl, combine 2 cups of all-purpose flour, 1 teaspoon of baking powder, and a pinch of salt. Set aside. In a separate large mixing bowl, cream together 1 cup of unsalted butter and 1 1/2 cups of granulated sugar until light and fluffy. Add 3 large eggs, one at a time, beating well after each addition. Mix in 1 teaspoon of vanilla extract. Gradually add the flour mixture to the wet ingredients, alternating with 1 cup of whole milk. Beat until just combined.

Baking Tips and Techniques

Pour half of the batter into the prepared baking dish, spreading it evenly. Layer the sugared rhubarb pieces over the batter. Pour the remaining batter over the top, spreading gently to cover the rhubarb. Tap the dish on the counter to release air bubbles. Bake in the preheated oven for 45-50 minutes, or until a toothpick inserted into the center comes out clean. Allow the cake to cool in the pan for at least 20 minutes before serving. For a classic touch, dust the top with powdered sugar. Enjoy a slice of Oma’s Rhubarb Cake warm or at room temperature.
