Tips for Perfect Margarita Lime Cake Bars

• Zest before you juice: Always zest your limes before cutting them — it’s easier and less messy.
• Use fresh limes: Bottled lime juice can taste bitter; fresh juice adds real brightness.
• Adjust the booze: You can skip the tequila or replace it with orange juice if you prefer a non-alcoholic version.
• Don’t overbake: Keep the bars soft and moist by baking just until the edges start to turn golden.
• Cool completely: Glazing too early will cause the topping to melt. Let them cool fully first.

Fun Fact: Why Lime and Tequila Are a Match Made in Heaven
