Best Side Dishes for S’mores Brownies

Common Mistakes to Avoid
S’mores Brownies can be a delightful treat, but some common mistakes can hinder your baking experience. Here are a few tips to ensure your brownies turn out perfect.
- Overbaking the brownies: Keep an eye on your brownies while baking. Follow the box instructions closely to avoid dry and crumbly results.
- Not crushing graham crackers enough: Ensure the graham crackers are finely crushed for even distribution. Larger pieces won’t blend well with the marshmallows.
- Ignoring the broiler: Do not leave the marshmallows unattended under the broiler. They can quickly go from perfectly toasted to burnt in seconds!
- Skipping cooling time: Allowing the brownies to cool before cutting helps them set properly. Cutting too soon may result in messy squares.
- Using stale ingredients: Check that your marshmallows and graham crackers are fresh. Stale ingredients can ruin the texture and flavor of your S’mores Brownies.

Storage & Reheating Instructions
Refrigerator Storage
- Store leftover S’mores Brownies in an airtight container for up to 3 days.
- Place parchment paper between layers to prevent sticking.
Freezing S’mores Brownies
- Wrap individual squares tightly in plastic wrap, then place them in a freezer-safe bag.
- They can be frozen for up to 3 months.
Reheating S’mores Brownies
- Oven: Preheat to 350°F (175°C). Warm brownies in foil for about 10 minutes.
- Microwave: Heat a brownie square for 10-15 seconds for a gooey treat.
- Stovetop: Place in a skillet over low heat, cover with a lid, and warm gently.
