Peanut Butter Cookie S'Mores Cups

These cookie cups are so easy to make and super tasty.

This recipe was inspired by spending some time at a cottage.

All the time spent around the campfire got me thinking a lot about s’mores.

I raided my cupboards to see what I could come up with for a s’mores inspired treat.

Luckily I had lots of marshmallows because that’s the most important part and some semi-sweet chocolate chips.

I also found some mini Reese’s Pieces candies and decided to throw those in there too.

I decided to make peanut butter cookies as the base because I’m actually not a huge fan of graham crackers.

I started off by by combining some peanut butter, softened butter, brown sugar and granulated sugar in a mixing bowl using an electric mixer.

Then I added some eggs and vanilla extract and continued mixing.

Then I added in the flour, baking powder, baking soda and salt.

I continued mixing until all of the ingredients were fully combined.

Then I pressed the peanut butter cookie dough into some well greased muffin tins to form cups.

I greased my muffin pans with Pam Spray For Baking.

I use this cooking spray for pretty much everything because I find it way less greasy than other sprays and also very effective.

I’ve never had trouble removing anything from a pan when using this spray.

I baked the cookies until they were just slightly under cooked and then removed them from the oven.

I filled the cups with some chocolate chips, marshmallows and mini Reese’s Pieces and returned them to the oven until the marshmallows started to brown.

Once the marshmallows started to brown I removed the cookies from the oven.

I allowed them to cool slightly before taking them out of the pan so that the would hold together better.

I love to enjoy these Peanut Butter Cookie S’mores Cups while they are still warm from the oven with melted chocolate and gooey marshmallows.
