  • Bring Ingredients to Room Temperature: Ensure your butter, eggs, and sour cream are at room temperature. This helps in achieving the best texture.
  • Let Cake Cool Completely: Allow the cake to cool completely before glazing to prevent the glaze from melting off.
  • Experiment with Toppings: Feel free to add toasted coconut or crushed graham crackers on top for an added crunch and texture.
