How to Perfect 4th of July Cake-Mix Cookie Bars
To ensure your 4th of July Cake-Mix Cookie Bars turn out perfectly every time, consider these helpful tips.

Use room temperature ingredients: Let your butter and eggs sit out before mixing. This ensures better blending and texture.

-
Check for doneness: Use a toothpick inserted in the center to check if they are done. It should come out clean or with a few crumbs attached.
-
Cool completely: Allow the cookie bars to cool in the pan before cutting. This helps them hold their shape better when sliced.
