Pro Tips for 4th of July S’mores Bars
- Graham Cracker Mix: Ensure the graham cracker crumbs are finely crushed for a smooth crust that holds together well. Larger chunks may lead to crumbling.

- Layering Ingredients: Spread the chocolate chips and mini marshmallows evenly, avoiding clumps. This guarantees every bite of your 4th of July S’mores Bars is deliciously balanced.
- Baking Time Caution: Watch the marshmallows closely during the second bake; they should be golden brown, not burnt. Burnt marshmallows can taste bitter!
- Cooling Period: Allow the bars to cool completely before cutting. This helps them set properly and makes slicing much easier without falling apart.
- Sprinkle Sparingly: When adding red and blue sprinkles, a light hand ensures they stick without overwhelming the festive look of your S’mores Bars.
