FAQs

Can I use natural peanut butter?

Yes, but stir well as it’s thinner than regular peanut butter.

How do I keep my cookies soft?

Don’t overbake! Remove them when they look slightly underdone, as they firm up while cooling.

Can I use Dutch-process cocoa powder?

Yes! It gives a deeper chocolate flavor but may require an extra pinch of baking powder.

Why did my cookies spread too much?

Make sure the dough isn’t too warm—chill it for 15 minutes if needed.

Can I make these cookies ahead of time?

Yes! Prepare the dough and refrigerate it for up to 2 days before baking.

What’s the best way to swirl the peanut butter?

Use a toothpick or knife to gently mix the peanut butter into the dough without over-mixing.

Can I use white chocolate instead of semi-sweet?

Absolutely! White chocolate pairs beautifully with peanut butter.

How do I get thicker cookies?

Chill the dough before baking and use parchment paper instead of greased pans.

Can I add peanut butter to the cookie dough instead of swirling it?

Yes! Mix 2 tablespoons of peanut butter into the batter for an all-over nutty flavor.

Do these cookies taste like brownies?

Yes! They have a rich, fudgy brownie texture with crispy edges and a gooey center.
