  3. Incorporate Eggs: Add the eggs one at a time, beating well after each addition.
  4. Add Flavors: Mix in the grated key lime zest, vanilla extract, and key lime juice for a burst of citrusy goodness.
  5. Alternate Dry and Wet Ingredients: Gradually add the flour and 2% milk in alternate batches, ensuring each addition is well incorporated.

Top 4 Mistakes and How to Avoid Them

1. Overmixing the Batter

Overmixing can lead to a dense cake. To avoid this, gently fold in the dry ingredients and mix only until combined. This ensures a light and fluffy texture.

2. Incorrect Oven Temperature

Ensure your oven is preheated accurately. A too-hot oven can result in a burnt exterior and undercooked interior. Invest in an oven thermometer for precision.

3. Neglecting Room Temperature Ingredients

Using room temperature eggs and butter ensures proper emulsification and a smoother batter. Cold ingredients can lead to an uneven texture.

4. Rushing the Cooling Process

Allow the cake to cool in the pan for the specified time. Rushing this step may cause the cake to break or stick to the pan.
