Giant Cookie for One

If you’re like me, there’s always that moment where you really crave a cookie. But then you realize that to make a dozen cookies means creating a big mess in the kitchen. A dozen baked cookies means being tempted to eat the entire batch of cookies.

That’s why this giant cookie for one is the answer to all of our problems. Technically, you could break this cookie up into fourths and share, but I say eat it all yourself! One cookie, less mess, and you’ve satisfied your cravings.

When you serve this single serving cookie warm out of the oven, the chocolate is melted and the Reese’s Pieces crack open to reveal a melted center. Perfection.

Plus, it has peanut butter in it, so it’s healthy right? Protein anyone?

With hardly any clean up involved, this cookie for one is the best for that quick cookie fix. It’s perfectly crunchy on the outside and soft and gooey on the inside. If you can’t help yourself and need to make more than one, try these Kitchen Tips for Freezing Cookie Dough.

How to Make a Cookie for One

Chocolate peanut butter cookies are a breeze to make! If you’ve made regular chocolate chip cookies before, you can certainly make this single serve cookie.

Here are the basic steps for making a cookie for one:

  1. Whisk together the butter and sugars, then whisk in the egg and vanilla.
  2. Stir in the peanut butter, then the dry ingredients.
  3. Scoop the dough onto a parchment paper-lined baking sheet.
  4. Bake for 16 to 18 minutes (this giant cookie needs more time to bake since it’s so large).

Can I Make This as a Small Batch of Cookies Instead?

Of course! You can probably squeeze four regular-sized cookies out of this recipe. Just note that you’ll need to reduce the bake time significantly (a regular batch of cookies will likely require around 10 minutes in the oven).

Can I Make This Giant Cookie Peanut-Free?

For peanut allergies, feel free to substitute almond butter for the peanut butter. Barney Butter brand almond butter is great because it is produced in an almond only facility and has a texture that resembles peanut butter.

You’ll also want to leave out the Reese’s Pieces. Double up on the chocolate chips or substitute plain M&M’s if you prefer.

Tips for Making a Giant Cookie for One

If desired, you could likely add other mix-ins to this single serve cookie. Instead of chocolate chips, you could use chopped nuts or additional Reese’s Pieces. You could also use M&M’s, butterscotch chips, or peanut butter chips. Just don’t add more mix-ins than the recipe calls for, otherwise your chocolate peanut butter cookie might not turn out correctly.

I used all-natural peanut butter in this single serve cookie recipe, but you may be able to use regular peanut butter from a brand like Jiffy or Skippy. But note that all-natural peanut butter does work well here!

Lastly, the cookie can be frozen after it’s baked. Let it cool completely, then seal inside a freezer bag for later. You can reheat the giant cookie in the microwave to make it gooey again.

What Readers Are Saying

“I made the chocolate peanut butter cookie(s), one for my husband and one for myself. I didn’t have any Reese’s pieces or m&m’s on hand so I used 1/4 C big chocolate chips and 1/4 C small chocolate chips in each cookie. We both thought they were DELICIOUS! They were easy to make. Thank you for this recipe.” — Lindsey
