The other day I was craving a cookie. But, instead of making a whole batch of peanut butter cookies, I made this. A single, giant cookie.

This cookie is super peanut buttery. Like a container of creamy peanut butter collided with a chocolate chip cookie. I’d recommend some milk to wash it all down.

The cookie is easy to prepare and then into the oven it goes. A dozen minutes later and you’ll have a freshly baked giant cookie all to yourself. Or if you’re feeling very generous, you can always share half the cookie with someone else.

  • 1/4 cup creamy peanut butter
  • 1/4 cup light brown sugar packed
  • 1/4 tsp baking soda
  • 1 tbsp of a lightly whisked egg
  • 2 tbsp semisweet chocolate chip or chocolate chunks


  • Preheat oven to 350°F. Line a baking sheet with a silpat mat or parchment paper.
  • In a small bowl, combine the first four ingredients. Mix with a small whisk until batter is smooth. Add in half of the chocolate chips/chunks and mix.
  • Using a small spatula, scrape cookie dough onto baking sheet. Using hands, gently shape to form a round cookie shape. Press remaining chocolate on top.
  • Bake for approximately 13-15 minutes until cookie is done. The edges should be browned and the surface should have cracks everywhere. Remove cookie from the oven. Cookie will still be slightly soft and not quite set. Let cookie cool on rack for about 15 minutes to settle and set before removing and eating.

  1. This recipe is bomb! It was perfect and I enjoyed every bite! Is it possible to use a small cookie scoop to make smaller cookies? My 5 year nephew loved them as well but absolutely hated that I broke the cookie into smaller pieces for him so he wouldn’t eat the whole thing. Will the cookie come out to the same great cookie if I were to do that?

  2. Heavenly …. delicious …  first time I’ve made something and it looks identical to the picture displayed! Thank you for the recipe! It enlarged quite a bit too.

  3. Do you think I’m doing it wrong if I have more than one of these?  YUMMY!

  4. Yum! Single serve cookies are my jam 🙂
