Top 4 Mistakes and How to Avoid Them

Mistake 1: Overmixing the Batter

Overmixing can lead to a dense cake. Gently fold the ingredients together to maintain a light and fluffy texture.

Mistake 2: Neglecting the Toothpick Test

Skipping the toothpick test may result in undercooked sections. Ensure thorough baking by inserting a toothpick into the center; it should come out clean.

Mistake 3: Using Cold Ingredients

Allow ingredients like cream cheese and butter to reach room temperature for a smoother blending process and better consistency.

Mistake 4: Not Greasing the Baking Dish Adequately

Proper greasing prevents sticking. Ensure an even application of nonstick cooking spray to guarantee easy removal.
