Reese’s Cookies

I don’t always love cake mix cookies. I’m more of a “from scratch” girl, but I make a few exceptions, like gooey butter cookies and these peanut butter reese’s pieces cookies.

They’re super soft, thick and chewy cookies, that are so easy to make.

If you like classic peanut butter cookies, you’ll love this shortcut that is full of peanut butter goodness.

If you want similar flavors made from scratch, try my Reese’s Pieces Peanut Butter Blondies.

Why you’ll love this Reese’s Cookie recipe

Peanut butter lover’s dream – There is peanut butter in the dough, reese’s pieces candies throughout…and maybe some additional candies on top of the cookies for good measure.

Easy cookie recipe – Starting with cake mix (& only 5 other simple ingredients) makes it a great beginner recipe for new bakers or younger helpers.

No chill – You don’t even need to chill the dough before baking, so this is a great recipe to make when you have just a little bit of time.

New favorite cookie – Much like my peanut butter cup cookies (that only have 5 ingredients), you’ll get a ton of peanut butter flavor in these delicious cookies. Perfect with a tall glass of milk.

Equipment you’ll need

  • Mixing Bowl – One large bowl is all you’ll need.
  • Hand Mixer – I opt for a hand mixer more often than my stand mixer, but either works. You could even just stir these if you don’t want to get out an electric mixer.
  • Cookie Scoop – I have a variety of sizes of cookie scoops.They make the easiest, most uniform cookie dough balls. In this batch, I used a size 50, which holds just over 1 tablespoon of dough.
  • Baking Sheets – I like to use a lipped baking sheet so no dough balls roll off and hit the floor. For the best results, line the pans with parchment paper or silicone mats.

Cookie Scoop Pro Tip 🍪

The size of the cookie scoop will be printed on the inside metal piece (the piece that pushes the dough out). I used a size 50 for these cookies, which is pretty standard. It holds just over 1 tablespoon of dough.

Below is a list of the ingredients you’ll need to gather to make this recipe. Scroll all the way down for the full recipe card.

  • Yellow Cake Mix – One 15.25 ounce yellow cake mix. Specifically, I used Duncan Hines Butter Golden here.
  • Peanut Butter – Creamy peanut butter, but crunchy would be good, for added texture.
  • Butter – Unsalted or salted butter, softened to room temperature. I like to use salted to balance the sweet.
  • Water
  • Eggs – Two large eggs.
  • Reese’s Pieces – Mini reese’s pieces or full sized can be used.

How to make delicious Reese’s Pieces Cookies

  1. STEP ONE: First, in a large mixing bowl, add the cake mix, peanut butter, softened butter, water, and eggs. Use a hand mixer to blend until fully incorporated.
  2. STEP TWO: Next, stir in the Reese’s Pieces until they’re evenly distributed.
  3. STEP THREE: Then, use a cookie scoop to portion out the dough to a parchment lined baking sheet (you can press additional candies to the top of each cookie, if you want) and bake for 10 minutes at 350° F or until just golden.
  4. STEP FOUR: Let the cookies cool on the pan for a few minutes before removing and enjoying!

When to serve them

These cookies make a fun weekend or after school treat but the brown, orange, and yellow colors of Reese’s Pieces, make me think fall events.

They’d be great served at a Halloween party, Thanksgiving, tailgating, or any other fall occasion.

Tips & Suggestions

  • Want chocolate reese’s pieces cookies? Swap out the yellow cake mix for chocolate. Otherwise, follow the recipe as written.
  • Try some additional mix-ins – semisweet chocolate chips, peanut butter chips, white chocolate chips, butterscotch chips…whatever you’re in the mood for.
  • For added texture, try using chunky peanut butter instead of creamy.

How to store leftovers

Leftovers should be stored in a ziplock bag or airtight container at room temperature. They’ll keep for up to a week.

Can I freeze them?

Yes! I like to freeze the dough before baking them.

Scoop the balls of dough onto a prepared baking sheet, cover with plastic wrap and freeze until solid. Once frozen, drop the dough balls into a freezer bag and store for up to 3 months.

Bake them straight from frozen adding a couple minutes to the bake time.

Do Reese’s Pieces have chocolate?

Nope, unlike Reese’s peanut butter cups, there is no chocolate in Reese’s Pieces. They are candy coated peanut butter candies.

How many does it make?

Using a 1.5″ cookie scoop, it made 27 cookies.
