These Peanut Butter Cup Cookies are the perfect little treat. I take mini peanut butter cups and place them right into just-baked tart-shaped cookies for a delicious bite-sized dessert that features the ultimate combination of peanut butter and chocolate.

The Best of Both Worlds Cookies

Every year I make these Peanut Butter Cup Cookies, and every year they are a big hit, because who doesn’t love the combination of chocolate and peanut butter? These chocolate peanut butter cookies are like mini tartlets, as I bake them in a mini muffin tin. I never know what to call them, as they can be tartlets or cookies, but I guess it doesn’t really matter because they fit both categories and are delicious regardless of what I call them.

I like serving these at Christmas, using them for cookie exchanges, or just baking them for parties or get-togethers. I lay the dough in the mini muffin tin, and once baked, I add the Reese’s peanut butter cup. What I get is a soft, chewy peanut butter cookie with a burst of chocolate with every bite. Believe me, once you taste these cookies, you’ll be hooked too. When I’ve got a laundry list of stuff that needs space in the oven, these no bake chocolate peanut butter cookies are my go-to option.

Tips for Beginners

• Change up the candies. Use Twix, Snickers, or even M&M’s instead of the peanut butter cups for a change in flavor.
• Use room temperature ingredients. Room temperature ingredients will blend more easily, making it easier to mix the batter.
• Don’t overmix the dough. Overmixing can lead to tough cookie dough as it overdevelops the gluten and adds more air to the batter, which in turn can change the texture of the baked cookie.
• Use a cookie scoop. A cookie scoop or measuring spoon will ensure the dough balls are all the same size and bake at the same pace.
• Unwrap the Reese’s peanut butter cups. Make sure the peanut butter cups are ready to go when you take the cookies out of the oven, as you want them to melt into the cookies while they are warm.

  ½ cup unsalted butter, ½ cup creamy peanut butter

  ½ cup dark brown sugar, ½ cup granulated sugar
• Add egg and mix until well combined.

• Let cool and set for 2 minutes, then remove carefully (I use a thin table knife) and place on a cooling rack. If the cookies fall apart when trying to remove from the pan, wait another minute and they should come out okay.)

Equipment

• Kitchen Scale (optional)
• Mini Muffin Tin
• Hand Mixer

Becky’s Tips

• Press other types of mini candies into these cookies, such as Twix, Snickers, or even M&M’s.
• Use room temperature ingredients so they blend well. 
• Mix the dough just until it’s combined so it doesn’t turn out tough.
• For consistently sized dough, use a cookie scoop or measuring spoon.
• Have the peanut butter cups unwrapped and ready to go when the cookies come out of the oven.
• Store in an airtight container at room temperature for up to 3 days, in the refrigerator for up to 5 days, or in the freezer for up to 1 month.

How to Store

Store uneaten cookies in an airtight container on the kitchen counter for up to 3 days or in the fridge for up to 5 days.

Freeze

Freeze unbaked dough in the muffin tin, and once frozen, remove and transfer to a Ziploc bag. Bake from frozen, adding a few extra minutes to the bake time, or thaw in the fridge and bake.

Freeze leftover peanut butter cup cookies for up to 1 month; thaw at room temperature before enjoying again.

Serving Suggestions

I like serving these bite-sized snacks with a glass of oat milk for the kids and either a bulletproof coffee or a cold brew for myself. These cookies are great for entertaining, as they make a big batch, though I do like to make them just for us and stash them in the freezer so I can pull out a few for an afternoon treat.
