  • 2 large eggs
  • 1 teaspoon vanilla extract
  • 1 ½ cups all-purpose flour

Butter Sauce

Instructions
 

Preparation

  • Preheat your oven to 350°F (175°C) and grease a 9-inch round cake pan with butter and flour.
  • In a large mixing bowl, beat together softened butter and granulated sugar until light and fluffy, about 2-3 minutes.
  • Add the eggs one at a time, ensuring each is fully integrated before adding the next.
  • Mix in the vanilla extract.

Mixing Ingredients

  • In another bowl, combine the flour, baking powder, and salt. Whisk to remove lumps.
  • Gradually add dry ingredients to the wet mixture, alternating with buttermilk, and mix until just combined. Avoid overmixing.
  • Gently fold in the chopped rhubarb.

Baking

  • Pour the batter into the prepared cake pan and spread evenly.
  • Bake for 30-35 minutes, or until a toothpick inserted into the center comes out clean.

Butter Sauce Preparation

  • While the cake bakes, melt 1/4 cup of butter in a saucepan. Stir in 1 cup of powdered sugar and a splash of milk until the desired consistency is reached.

Serving

  • Let the cake cool for a few minutes before inverting onto a plate. Serve drizzled with warm butter sauce and dusted with powdered sugar, if desired.
