1. Can I use a different type of chocolate instead of milk chocolate chips?

Absolutely! Feel free to experiment with dark chocolate, white chocolate, or even a combination of chocolates to suit your taste preferences.

2. Can I make these squares in advance?

Yes, you can! These squares store well in an airtight container in the refrigerator for up to one week. Just be sure to let them come to room temperature before serving for the best texture.

3. Can I substitute the caramel sauce with something else?

While caramel sauce adds a delicious gooey layer to these squares, you can certainly get creative with substitutions. Consider using chocolate ganache, peanut butter, or even Nutella for a unique twist!

4. Can I freeze these squares?

Yes, you can freeze these squares for longer-term storage. Wrap them tightly in plastic wrap or aluminum foil, then place them in an airtight container or freezer bag. They should keep well for up to three months. Just thaw them in the refrigerator before serving.

5. Can I double the recipe to make more squares?

Absolutely! Simply double the ingredients and use a larger baking pan to accommodate the increased quantity. Just be sure to adjust the cooking time accordingly and keep an eye on them to prevent over-browning.
