Peanut Butter Oatmeal Sandwich Cookies

It's no secret that I love cookies.  So much that I've put myself on a hiatus from making them - things have gotten a little out of hand lately!  When I saw this recipe pop up on Annie's Eats, I bookmarked it, knowing the combo of peanut butter and oats would be delicious.  Then I saw it the next week on Pink Parsley, and knew I had to try it...now.  I actually made these a few months ago, and they were so good that I made them twice in one week!   The first time was for Mother's Day, when they were enjoyed by my family and John's (John's mom said that they were my new "speciality" and his grandma went back for seconds...or thirds), and the second time was for new mama Kelly when I got to bring her and her new family dinner and of course dessert.


I think everyone loved how soft and chewy they were, and the frosting in the middle was to die for!  Plus, a sandwich cookie is a fun change and somehow makes eating four cookies plus frosting seem like you're only eating two!  If you haven't tried these yet, bookmark this recipe and make them soon - they will not disappoint! 


Peanut Butter Oatmeal Sandwich Cookies
Recipe Source: Annie's Eats, Pink Parsley Catering
Makes about 18 sandwich cookies


Ingredients


3/4 cup all-purpose flour
1/2 teaspoon baking soda
1/4 teaspoon baking powder
1/2 teaspoon salt
8 tablespoons butter (room temp)
1/2 cup creamy peanut butter
1/2 cup granulated sugar
1/2 cup brown sugar, packed
1 large egg
1 teaspoon vanilla extract
1 cup quick-cooking oats

For the Filling

3 Tablespoons unsalted butter, at room temperature

1/2 cup creamy peanut butter

1 cup confectioners' sugar

3 Tablespoons heavy cream 

Directions

Preheat the oven to 350 degrees.  Cream the butter, peanut butter, and sugars over medium-high speed until light and creamy.  Add in the egg and vanilla and mix until well blended.

In a separate bowl, mix together the flour, baking soda, baking powder, and salt.  Mix in with the wet ingredients until just incorporated.  Add in oats and mix with a large wooden spoon.  

Arrange dough on cookie sheets lined with parchment paper, paying special attention to make them all the same size so the sandwiches form easily.  Bake for about 10 minutes - you want them to be especially chewy so they don't crumble when you bite into the sandwiches.

For the frosting

Cream the butter and peanut butter.  Slowly add in the sugar, and mix until well blended.  Add in the heavy cream and mix on medium high for a few minutes until smooth.

Once the cookies have cooled completely, pair them up by size.  Spread one cookie with the frosting and press the two cookies together.
