Common Mistakes to Avoid
Making Patriotic Sugar Cookie Bars can be a delightful experience, but it’s essential to avoid common pitfalls.
- Skipping the Cooling Step: Not allowing the cookie bars to cool completely before frosting can lead to a melty mess. Always wait until they are entirely cooled on a wire rack.
- Overmixing the Dough: Mixing too much after adding flour can make the bars tough. Mix just until combined for a soft texture.
- Incorrect Oven Temperature: Baking at the wrong temperature can result in undercooked or burnt bars. Use an oven thermometer to ensure accuracy.
- Not Using Parchment Paper: Baking directly in the dish without parchment can lead to sticking. Always line your baking dish for easy removal and cleanup.
- Neglecting to Measure Ingredients Accurately: Eyeballing ingredients can ruin your bars. Use precise measurements for the best results.
