Common Mistakes to Avoid
Avoiding common mistakes can elevate your Fireworks Sugar Cookie Bars Recipe from good to great. Here are some pitfalls to steer clear of:
- Overmixing the dough: Mixing too much can lead to tough cookie bars. Mix just until ingredients are combined for a softer texture.
- Ignoring oven temperature: Not preheating your oven can lead to uneven baking. Always ensure your oven is at the correct temperature before placing your cookie bars inside.
- Using cold butter: Cold butter will not cream well with sugar, resulting in dense bars. Make sure your butter is softened for optimal fluffiness.
- Skipping the cooling step: Frosting warm cookie bars can result in a melted mess. Allow your bars to cool completely before adding frosting for a beautiful finish.
- Not measuring flour accurately: Too much or too little flour can affect texture. Use a kitchen scale or spoon and level method for precise measurements.
