Frequently Asked Questions

Can I make these bars gluten-free?

Yes, you can substitute the all-purpose flour with a gluten-free flour blend that measures cup-for-cup. Make sure to check that all other ingredients, especially the butterscotch chips, are gluten-free to maintain the integrity of your dessert.

How can I make these bars less sweet?

To reduce the sweetness, you can decrease the amount of brown sugar slightly or use a sugar substitute like coconut sugar. Additionally, you can opt for unsweetened chocolate chips instead of butterscotch chips to balance the sweetness.

Can I freeze the peanut bars?

Absolutely! These bars freeze well. Wrap them individually in plastic wrap and then place them in a freezer-safe container. They can be frozen for up to three months. To enjoy, simply thaw at room temperature or microwave for a warm treat.
