Common Mistakes to Avoid
Creating S’mores Brownies can be a joyful experience, but avoiding common pitfalls is essential for perfect results.
- Not Following Box Directions: Always follow the instructions on your brownie mix package. This ensures the right texture and flavor.
- Overbaking the Brownies: Keep an eye on the baking time. Overbaking can lead to dry brownies. Use a toothpick to check for doneness.
- Skipping the Broiler Step: Don’t skip broiling the marshmallows. This step gives them that perfect toasted flavor and gooey texture.
- Insufficient Cooling Time: Allowing your brownies to cool too quickly can make cutting them messy. Let them cool completely for cleaner squares.
- Using Stale Ingredients: Ensure your ingredients are fresh, especially marshmallows and chocolate. Stale items won’t provide the same taste or texture.
