I could wax poetic all day about my love for peanut butter cookies. Growing up, my mom made them often. Rolling the cookie dough in sugar before giving the cookies their signature branding: Two forks to make a criss cross before baking. The only real difference with this version is that I added dark chocolate chunks. Pretty sure my mom wouldn’t mind!

FYI, my favorite chocolate chunks are from Trader Joes! In a pinch, I’ll cut up a full chocolate bar into chunks.

You’re likely here because you’re looking specifically for a high altitude cookie recipe. I get so many emails asking if my recipes are already adjusted for high altitude and the answer is: YES!!! Often times (like this one) I’ll find a well rated cookie recipe on the Internet and then adjust it until I get it right. Decreasing the sugar a tad, decreasing the leavening a bit, and boosting the flavor are my not so secret rules when playing around with a recipe.

If this isn’t the million dollar question I don’t know what is! My answer: chunky peanut butter for sandwiches and smearing on to apples, creamy for baking and especially when baking cookies. The reality is you can use whatever you like best. I will say that I rarely use a natural peanut butter when baking. While it’s my favorite for everyday use, the blended store bought variety is best for baking!

The peanut butter I like for baking is JIF Natural.

Chocolate chunks, chocolate chips, a chopped up chocolate bar…..any and all will work! A few weeks ago I made these and used up the last bit of three different bags of chocolate chips: Regular sized milk chocolate chips, mini semi-sweet chips, and also some chocolate toffee bits. As you can imagine, the cookies were amazing. If you prefer a less sweet cookie, use dark chocolate and if you want one a little more sweet, opt for milk chocolate or even sub for some white chocolate!

I almost always freeze either unbaked cookie dough or the baked cookies when I’m making a batch. To freeze the cookie dough, form the dough into balls and freeze in a ziplock bag or something airtight. When ready to bake, thaw the cookie dough just a bit and then roll the cookies in sugar just before baking as directed. If freezing the baked cookies, let them cool completely before placing in a ziplock or airtight container. Baked cookies will freeze for up to 3-4 weeks.

Chewy interior and a crispy exterior, these peanut butter chocolate chunk cookies are one of my favorites!


  • 1 cup butter, room temperature
  • 1 cup creamy peanut butter
  • 1 cup granulated sugar
  • 1 cup packed light brown sugar
  • 1 1/2 teaspoons vanilla extract
  • 3 large eggs
  • 4 cups all-purpose flour
  • 1 1/2 teaspoons baking soda
  • 1/2 teaspoon salt

  • 1/3 cup coarse sugar for rolling cookies


  1. Preheat oven to 375 F degrees.
  2. In a medium bowl, mix the flour, baking soda and salt; set aside.
  3. In a large mixing bowl, cream the butter, peanut butter and sugars until light and fluffy, about 3 minutes. Add vanilla and mix. Add the eggs, one at a time, beating well after each addition.
  4. Add flour mixture and mix just until combined. Stir in chocolate chunks.
  5. Use a heaping tablespoon and scoop the cookie dough into a small bowl. Gently roll between your hands to form a ball.
  6. Put the coarse sugar in a shallow bowl or plate. Roll the cookie balls in the sugar and place on a lined baking sheet. Gently press the cookies down with the bottom of a cup.
  7. Bake cookies at 375 F degrees for 9-10 minutes just until cookies are set. Remove from oven and let the cookies cool on the rack for 5 minutes and then transfer cookies to a cooling rack to finish cooling fully.
