Drop dough using an ice cream scoop for uniform cookies that bake evenly.
Don't overbake; check at 12 minutes for chewier texture, closer to 18 for crispier edges.
Stir peanuts and candy by hand to avoid breaking chocolate pieces or crushing peanuts.

Common Mistakes
Overmix after adding flour to avoid tough cookies; mix just until combined.
Don't space cookies too close; they spread during baking and may merge.

FAQ
Can I use different mix-ins like pretzels or coconut?
Yes, substitute up to 2 cups total. Keep peanuts at 1 cup and reduce chocolate to 1 cup for balance. Pretzels add salt, so reduce added salt slightly.
What if my cookies spread too thin or stay too thick?
Thin spreading means dough was too warm or oven too hot; chill dough 30 minutes. Thick cookies indicate underbeating the butter or too much flour; measure flour by weight if possible.
How long do baked cookies keep and can I freeze them?
Baked cookies last 5 days in an airtight container. Freeze up to 3 months in freezer bags. Thaw at room temperature for 30 minutes before serving.
