These AAH-MAZING peanut butter chocolate chip cookies are simply out of this world, crazy good! Thick and chunky with a delicious chewy moistness in the centre! An easy, quick and perfect treat for anyone who loves a sweet pick-me-up.

You’d probably never expect that my first recipe post after this quiet absence, would be on something as simple as these thick, chewy peanut butter chocolate chip cookies.

It’s just that I had only begun to realise, over the course of this summer, how crazy my family was over cookies. I hate to admit it, but if anyone’s noticed, I am sorely lacking in cookie recipes on my blog.

It’s not for a lack of love for cookies, believe me, because I am equally smitten as everyone else in my family.

I first discovered real cookie love when I sunk my teeth into a CLASSIC CHOCOLATE CHUNK® cookie made by Cookies by George.

George’s cookies are the ultimate standard that I’ve always aspired to recreate at home! It’s too bad we don’t have a Cookies by George in Singapore, that would be a dream come true for me!

I’ve obviously got room to go towards creating my ultimate George’s cookie twin. But here’s a start, I hope, with what I can only describe as lip smacking, finger licking, super good, thick and chewy peanut butter chocolate chip cookies.

So, I just have to ask, my dear readers, what are cookies to you? Oh, do tell… I’d love to hear your stories!

For me, cookies are the snappiest treats I bake when I need something homemade that’s quick and easy to gift someone. Cookies are my pick-me-ups when I’m running on empty.

Cookies save me when I badly need a sugar whoosh to get me through the rest of my day. And cookies are the first things I pack when I’m about to go on walks and hikes.

Yup, cookies and me, we always go places together. We’re THIS (fingers crossed) tight.

I think everyone should have their go-to recipe for their favourite cookie, don’t you agree? Even if you’re not a cookie lover, you just never know when you’ll need to pull out a great recipe at a moment’s notice.

I’m so happy that I found an amazing one for these peanut butter chocolate chip cookies by The Kitchen Magpie. I promise you won’t be disappointed!

Up until now, my favourite go-to were these soft and chewy chocolate chip and nut cookies.

But now that I’ve tasted how peanut butter just rocks in this ahh-mazing combination with chocolate chips, I just can’t seem to look at chocolate chip cookies quite the same way again. I don’t think you can too, after this…

There are a couple of pointers you might find helpful before you get your bite into your slice of cookie heaven!

Peanut butter chocolate chip cookies

Can I use chunky in place of smooth peanut butter?

I say, use whatever you’d like! Just substitute chunky for smooth 1:1 ratio, as the amount of nuts in chunky peanut butter are not significant enough to dramatically change the outcome of these cookies.

Should I use bitter-sweet or semi-sweet chocolate chips?

Both would work equally well, though I personally prefer bitter-sweet to offset the sweetness of this cookie.

This recipe uses 2 cups, which I know, may seem like an awful lot of chips. But it’s what makes these cookies so fudgy and decadent!

Can I reduce the sugar?

This recipe has had the amount of brown sugar reduced by 1/4 cup. That’s 25% less sugar than the amount in the original recipe.

Still, the cookies are sweet and delightfully moist. These stay moist for up to 3 days after baking if stored in an air-tight container in a dry, cool place.

You could reduce more sugar, but you might not get as moist a cookie as you’d like. You’d really have to experiment and see what balance of sweetness and moistness works best for you.

Can I replace light brown sugar with white sugar?

Light brown sugar is what makes these cookies turn a lovely golden brown with a delightful moistness.

White sugar will work fine when substituting brown sugar in equal quantity. The cookies will be crispier with white sugar, though that could be how you like your cookies?

How can I tell when these cookies are baked just right?

If you’re after crisp at the edges, and soft, chewy moistness in the centre, the key is to UNDER-BAKE your cookies!

Under-baking doesn’t mean the cookies aren’t done. It just ensures that the cookies stay moist and chewy. Once the cookies begin to brown at the edges, remove them from the oven.

I took 12 minutes with each batch I baked on the middle rack in the oven. It may be more or less with your oven. The cookies will be very soft when immediately out from the oven.

Let cookies cool on the tray for at least 15 minutes to allow them to firm up enough for handling. Otherwise, they may easily crumble or fall apart.

How can I get my cookies of uniform size, thickness and level on the tops?

First of all, these cookies are made deliberately big! I just love mine this way! You could, of course, make cookies in any size you like.

I recommend using an ice cream scoop (or cookie scoop) to scoop out the cookie dough onto the baking tray. This helps make cookies of more or less equal rounds.

It’s also really important that you DO NOT FLATTEN BEFORE BAKING. Place the rounded balls of cookie dough on the baking tray, spacing each about 1 1/2 to 2 inches apart from each other.

When the cookies are fresh out of the oven, they usually are slightly dome-shaped in the centre. Use a wide, flat spatula to lightly press on the cookie tops to level them.

Press lightly till the cookies are about 1/2 to 3/4-inch thick. Make thicker/thinner as you like. Allow the cookies to cool completely before storing.

How can I avoid my cookies from spreading thin during baking? 

I can’t guarantee that your cookies won’t spread thin once in a hot oven. They’ll still be awfully delicious, that much I can say!

I’ve been putting together this cookie dough in my brother’s kitchen in Canada. His kitchen is really cool, hovering near 18°C.

But I know that it’s going to be totally different ball game when I get back to Singapore. There, I’ll have to contend with a humid and warm 27°C!

In any case, I highly recommend chilling your cookie dough in the refrigerator for at least 30 minutes. One of our readers here highly recommended that you freeze the cookie dough for at least 2 hours.

Do this after you’ve shaped into balls. If that still doesn’t quite resolve the spreading, then tweak the recipe, cutting back a bit on the butter or increasing the flour by 2 to 3 tablespoons.

These AAH-MAZING peanut butter chocolate chip cookies are simply out of this world, crazy good! If you love your cookies thick and chunky, with a delicious chewy moistness in the centre, you have to get to baking these right away! An easy, quick and perfect treat for anyone who loves a sweet pick-me-up! (Adapted from The Kitchen Magpie)


  • ½ cup unsalted butter, at room temperature
  • ¾ cup light brown sugar
  • 1 large egg
  • 2 tsp vanilla extract
  • ½ cup smooth, or chunky peanut butter
  • 1 ¼ cup plain flour
  • ½ tsp baking soda
  • ½ tsp salt
  • 2 cups chocolate chips, (use bitter-sweet or semi-sweet)


  • Pre-heat the oven to 190°C (375° F). Line a baking tray with baking or parchment paper.
  • In an electric mixer (or with a hand-held mixer) fitted with a paddle attachment, cream the butter and sugar together on medium speed until well combined, about 2 to 3 minutes.
  • Add the egg, and beat on low speed (mixture will curdle at first) until mixture comes together and is well combined. Add the peanut butter and vanilla extract. Beat for about one minute to combine well.
  • Sift together the flour, baking soda and salt. Pour into the butter mixture, beat on low speed until flour mixture is fully incorporated and comes together as cookie dough. Add the chocolate chips and mix with a spatula/long spoon by hand until evenly distributed throughout the dough. Refrigerate the dough for at least 30 minutes.
  • Using an ice-cream scoop, fill scoop with cookie dough and level with a spatula or flat blade. Release cookie dough from the scoop onto the prepared pan, spacing each about 1 1/2 to 2 inches apart.
  • Bake for 12 minutes, or until the cookies turn golden brown around the edges, and with a few uneven brown spots on top. Remove from the oven. The cookies should still be slightly dome-shaped, are very soft and fragile. DO NOT REMOVE from the baking tray at this point.
  • Using a flat spatula, press down lightly on each cookie until evenly flat and to your desired thickness, about 1/2 to 3/4 inch thick (or make thicker/thinner as desired).
  • Leave the cookies to cool completely on the baking tray after flattening for 10 to 15 minutes, or until firm enough to handle. Transfer to a cooling rack. Make the next batch of cookies with remaining cookie dough until it is used up.
  • Once completely cooled, store cookies in an air-tight container in a dry, cool place. These cookies will keep well for 3 to 5 days.


  • Reader’s Recommendation: After shaping cookie dough into balls, freeze for at least 2 hours to help reduce spreading.
