Whoopie Pie Cookies

My kids and I absolutely love whoopie pie cookies. Not only does it feel silly to say “whoopie pie”, but the yummy taste and the kid-friendly recipe make this one of our favorite treats to make together.

I’m a huge fan of any cookie sandwich, but whoopie pies have this sentimental place in my heart! Whoopie pie cookies are a sandwich of two cakey and fudgy chocolate cookies filled with a creamy marshmallow frosting.

Every time I eat one of them, I’m filled with happy memories of eating them as a kid!

And I love that now I can share that with my own kids. This recipe is so simple and fun and my kids love making it with me (and licking the spoon of course)!

You can expect little faces covered in chocolate crumbs, frosting smudges, and giant smiles when you eat this special treat!

  • To make your whoopie pie cookies, start by preheating the oven to 350 degrees.
  • Get a baking sheet ready by lining it with a silicone mat or parchment paper. 
  • Add the flour, baking cocoa, baking soda, baking powder, and salt to a medium-sized mixing bowl. 
  • Whisk together the dry ingredients until combined.
  • In a separate larger mixing bowl, add the sugar and oil and beat together until crumbly. 
  • Add in the eggs, milk, and vanilla. Beat again until the mixture is smooth.
  • Slowly add the dry ingredients and beat after each addition until combined. 
  • Use a cookie scoop or a tablespoon to scoop the dough and roll each scoop into a ball.
  • Place the dough balls on the prepared cookie sheet a few inches away. There should be about 24 balls. 
  • Gently use your hand to press down each ball of dough slightly.
  • Bake the whoopie pie cookies in the preheated oven for 7-10 minutes or until they are soft to the touch but firm around the edges.
  • Remove the cookies from the oven and cool for 5 minutes on the baking sheet.
  • Transfer the cookies to a wire cooling rack and let them cool completely. 
  • While your cookies, make your frosting by adding the butter and powdered sugar to a medium mixing bowl.
  • Beat the butter and sugar together until fluffy.
  • Add the vanilla and salt and beat again until fluffy and smooth.
  • Fold the marshmallow fluff into the butter mixture until well combined.
  • Place the bowl in the fridge to chill for about 20-30 minutes to let it firm up a bit. 
  • When the filling is ready, transfer it into a piping bag that is fitted with a large round tip.
  • Pipe the filling onto a cookie and top with a second cookie to create your whoopie pie cookies sandwich.

Tips Tricks and FAQs 

  • If you don’t have a piping bag or large round tip, you can also use a large disposable plastic bag. I use a gallon-sized bag and place my filling right inside. Then I snip a corner and pipe the frosting just as I would with a piping bag. They may not look as pretty as with a nice tip, but it’ll work fine, and more importantly, it’ll taste great. 
  • If you have a special event coming up, these cookies are perfect! A great way to make these cookies extra special is by adding sprinkles. To do this, place a pile of sprinkles on a plate. Then take your filled and finished cookie and roll it in the sprinkles so they stick to the filling. You’ll have the cutest little treat fit for any occasion!
  • Make sure that your filling is firm before you add it inside the cookies. If it is too soft, the cookies will be a mess when you try to eat them! If the filling has been in the fridge for a half hour and still feels too soft, try adding another ½ cup of powdered sugar and chilling again to firm it up. 

Storage

Store the cookies in an airtight container in your fridge for up to 3 days. If you prefer to eat them at room temperature, take them out about 15 minutes before you serve.
