FAQs

Can I use chunky peanut butter instead of creamy?

Yes, chunky peanut butter can be used if you prefer added texture from peanut pieces.

Can I melt the ingredients on the stovetop instead of the microwave?

Absolutely. Use a saucepan over low heat, stirring constantly until the mixture is smooth.

Are there alternatives to butterscotch chips?

You can substitute with white chocolate chips or additional semi-sweet chocolate chips, though the flavor will differ.

Can I add other mix-ins to the bars?

Yes, feel free to add nuts, dried fruits, or candies to customize the bars to your liking.

How do I prevent the bars from sticking to the foil?

Using non-stick foil or lightly greasing regular foil can help prevent sticking.

Can I make these bars vegan?

Yes, by using vegan chocolate and butterscotch chips, plant-based peanut butter, and vegan marshmallows.

Do I need to refrigerate the bars to set them?

Refrigeration helps the bars set firmly, but if you're in a hurry, placing them in the freezer for a shorter time can expedite the process.

Can I double the recipe?

Yes, double the ingredients and use a larger baking dish or two standard ones to accommodate the increased volume.

How long do the bars last at room temperature?

They can sit at room temperature for a few hours during serving, but for longer storage, keep them refrigerated.

Are these bars gluten-free?

The bars can be gluten-free if all ingredients used are certified gluten-free. Always check product labels to ensure they meet your dietary needs.
