What to Serve Peanut Butter S’mores Cookie Bars With

Top Tips for Perfecting Peanut Butter S’mores Cookie Bars

To ensure you make the best Peanut Butter S’mores Cookie Bars, be sure to follow these tips:

  • Use Room Temperature Ingredients: This helps create a smoother dough.
  • Don’t Overmix: Mixing just until combined will yield a softer texture.
  • Be Generous with the Marshmallows: The more, the merrier! They melt beautifully and add to the gooey goodness.
  • Experiment with Chocolate: Try using different types of chocolate chips like dark or white chocolate for a unique twist.

Storing and Reheating Tips

To store your delicious Peanut Butter S’mores Cookie Bars, place them in an airtight container at room temperature for up to 3 days. For longer storage, keep them in the refrigerator for up to a week. If you want to freeze them, wrap individual bars in plastic wrap and place them in a freezer-safe bag for up to three months.

When you’re ready to enjoy them again, simply let them thaw at room temperature or warm them up in the microwave for a few seconds. This will help melt the chocolate slightly and give them that freshly baked taste once more.
