Frequently Asked Questions
Can I freeze the cookie dough?
Yes. Freeze the assembled cookie dough balls for up to 2 months. Bake directly from frozen, adding 2–3 minutes to the baking time.
Why is my peanut butter leaking out?
The dough may not have been sealed completely. Make sure the filling is fully enclosed before baking.
Can I use chunky peanut butter?
Yes. Chunky peanut butter adds extra crunch, but creamy peanut butter creates the smoothest lava center.
Can I make smaller cookies?
Absolutely. Use half the filling for each cookie and reduce the baking time to 9–10 minutes.
How do I keep the center gooey?
Slightly underbake the cookies and allow them to cool for only 10 minutes before enjoying them warm.
