Dark Chocolate Chunk and Peanut Butter Chip Chocolate Cookies

If you think the world’s most perfect food pairing is chocolate and peanut butter, you’re in for a real treat.

These cookies combine chocolate and peanut butter, twice. You can never have too much.

There’s dark chocolate chunks and cocoa powder, with peanut butter chips and peanut butter.

They’re soft, chewy, gooey, and oh yes, full of chocolate and peanut butter.

They’re easy to make by creaming together peanut butter, butter, sugars, an egg, and vanilla.

Fold in flour, cocoa powder, cornstarch, and baking soda, before folding in the add-ins.

I’ve used cornstarch in these cookies, and in about 20 other cookie recipes, including Chocolate Chip and Chunk CookiesPeanut Butter Coconut Oil CookiesM&Ms CookiesSnickers CookiesTwix Bar CookiesCaramel Corn Chocolate Chip CookiesSmores CookiesLofthouse CookiesCandy Corn and White Chocolate Chip CookiesVanilla Melting Moments Sandwich CookiesOrange Creamsicle White Chocolate Cookies, and more.

It helps create softbatch-style cookies that are soft, moist, and supple, without turning cakey.

I chopped and used a Trader Joe’s 72% Pound Plus Bar. A tip before you start chopping is to put a piece of parchment on your cutting board and chop on that. You can easily slide the chopped chocolate right into the mixing bowl, and there’s no ground-in chocolate on your cutting board, making cleanup a breeze. I recycle the parchment and tuck it in with the remainder of the chocolate bar, and I’m already set up for next time.

If you you want to use semi-sweet chocolate chips you can, but they don’t melt and ooze as much as chopped chocolate does.

Don’t overbake, which is easy to do with dark cookies. They’ll fool you and will look raw, all the way up to the point they’re overdone and crunchy.

They’ll look glossy, shiny, and not appear done when you pull them, but firm up, dry out, and de-gloss as they cool, even more so than non-chocolate cookies.

They’re soft and chewy chocolate cookies, more so than they are peanut butter cookies. They’re dark, rich, and aren’t overly sweet.

They’re loaded with add-ins and texture in every bite. The glistening dark chocolate chunks, along with the chocolate-peanut butter dough, make for a very intense chocolate experience.

The peanut butter chips amplify the peanut butter flavor, and add a pop of sweetness, balancing the robust chocolate flavor.

Peanut butter and chocolate lovers, you’ve met your match.

Make sure not to overbake; dark cookies can fool you into thinking they’re still under-done, but firm up considerably as they cool.

1 large egg
3/4 cup creamy peanut butter (do not use homemade or natural peanut butter; it’s too runny and cookies could spread)
1/2 cup unsalted butter, softened
1/2 cup light brown sugar, packed
1/4 cup granulated sugar
1 tablespoon vanilla extract
1 1/4 cups all-purpose flour
1/2 cup unsweetened natural or Dutch-process cocoa powder (I used Trader Joe’s)
2 teaspoons cornstarch
1 teaspoon baking soda
pinch salt, optional and to taste
4 ounces dark chocolate, chopped (1/2 cup semi-sweet chocolate chips may be substituted)
1/2 cup peanut butter chips


  1. To the bowl of a stand mixer fitted with the paddle attachment (or large bowl and electric hand mixer), cream together the first 6 ingredients (through vanilla) on medium-high speed until light and fluffy, about 5 minutes.
  2. Stop, scrape down the sides of the bowl, and add the flour, cocoa, cornstarch, baking soda, optional salt, and mix on low speed until just incorporated, about 1 minute; don’t overmix.
  3. Add the chocolate, peanut butter chips, and blend until just incorporated.
  4. Using a medium 2-inch cookie scoop or your hands, form heaping two-tablespoon mounds (I made 17). After scooping the dough into mounds, I lightly rolled the dough mounds in my hands to make sure they were compacted. Dough may be slightly crumbly but holds together when squeezed. Place mounds on a large plate, and flatten them slightly.
  5. Cover with plasticwrap, and refrigerate for at least 2 hours, or up to 5 days, before baking. Do not bake with warm dough because cookies will spread and bake thinner and flatter.
  6. Preheat oven to 350F, line a baking sheet with a Silpat or spray with cooking spray. Place mounds on baking sheet, spaced at least 2 inches apart (I bake 8 cookies per sheet). Bake for 8 to 9 minutes, or until edges have set and tops are just beginning to set, even if cookies appear undercooked, pale, and glossy in the center. They firm up as they cool. (The cookies shown in the photos were baked with dough that had been chilled overnight, allowed to come to room temp for 15 minutes, and were baked for 8 minutes. They have slightly chewy edges with soft, pillowy centers). Allow cookies to cool on the baking sheet for 5 minutes before removing and transferring to a rack to finish cooling.
  7. Cookies will keep airtight at room temperature for up to 1 week, or in the freezer for up to 4 months. Alternatively, unbaked cookie dough can be stored airtight in the refrigerator for up to 5 days, so consider baking only as many cookies as desired and save the remaining dough to be baked in the future when desired.
