How to Perfect Lemon Oatmeal Crumble Bars

• Use Fresh Lemons: Freshly squeezed lemon juice gives the best flavor compared to bottled options. It enhances the tanginess and brightness of the filling.

• Chill Before Cutting: Allow the bars to cool completely and chill in the refrigerator before cutting. This helps them set properly and makes slicing easier.

• Don’t Overmix: When preparing your crumble topping, mix just until combined to maintain texture. Overmixing can lead to a dense topping.

Common Mistakes to Avoid

When making Lemon Oatmeal Crumble Bars, it’s easy to make a few common mistakes. Here are some tips to ensure your bars turn out perfectly.

• Incorrect Lemon Measurement: Using too much or too little lemon juice can affect the flavor. Always measure carefully for that perfect tang.
• Overmixing the Oatmeal Crust: Mixing too vigorously can lead to a tough crust. Combine just until ingredients are moistened for a crumbly texture.
• Skipping the Cooling Time: Cutting bars before they cool can cause them to fall apart. Allow them to cool completely in the pan before slicing.
• Inaccurate Oven Temperature: An oven that’s too hot may burn the topping while leaving the filling uncooked. Use an oven thermometer to ensure accurate baking temperatures.
• Not Using Parchment Paper: Not lining your baking dish can make it difficult to remove the bars. Always use parchment paper for easy lifting and clean-up.
