Homemade Oatmeal Cream Pies

adapted from: Bean Town Baker


3/4 c. unsalted butter, softened

2 c. packed brown sugar

2 eggs

1/2 tsp. salt

2 c. all-purpose flour

1 tsp. baking powder

1/2 tsp. ground cinnamon

2 c. quick-cooking rolled oats

2 tsp. baking soda

3 Tbl. hot water



Preheat oven to 425 degrees.  Lightly grease a baking sheet and set aside.  Cream butter and sugar until light and fluffy.  Add eggs and mix to combine.  In a separate bowl, sift together the salt, flour, baking powder and cinnamon.  Add to the creamed mixture.  Add the oats and mix until combined.  In a small dish, add the baking soda to the boiling water and stir into the rest of the batter.  Drop by the Tablespoon onto baking sheets, about 2-inches apart and bake until the cookies are just starting to turn golden around the edges, 8-11 minutes.  Cool the cookies on a wire rack.  Once completely cooled, spread vanilla frosting over flat side of one cookie and top with the flat side of another cookie.  Repeat.  Yield: around 44 cookies or 22 sandwiches. 

Jenn's Notes: I made a half a batch of both the cookies and the frosting.  I typed the recipe above with the measurements that I used.  The cinnamon is needed to help these taste like the store-bought ones, so don't leave it out.  I baked my cookies for 8-9 minutes.  (Remember you want them to be soft).  Don't judge the sandwiches the first night you make them, they really need to sit overnight in order to taste like a store-bought oatmeal cream pie.  They are delicious and I can't stop eating them!     



Whipped Vanilla Frosting

*This frosting takes a bit of advance planning since the frosting needs time to cool so plan ahead! 
*Makes about 4 cups frosting (plenty for two 9-inch cake layers)
*Best if used while fresh, because once it is refrigerated, it won't re-whip properly.  It will taste amazing for several days.
  

1 1/2 cups granulated sugar

1/4 cup all-purpose flour

3 tablespoons cornstarch

1/4 teaspoon salt

1 1/2 cups milk (I used 1%)

2 teaspoons pure vanilla extract

24 tablespoons (3 sticks) butter, cut into 24 pieces and softened at room temperature


In a medium bowl, combine the sugar, flour, cornstarch and salt. Slowly whisk in the milk until the mixture is smooth. Place a fine-mesh strainer over a medium saucepan and pour the milk mixture through the strainer into the saucepan. Cook the mixture over medium heat, whisking constantly, until the mixture boils and is thick enough that it starts to become difficult to easily whisk. This could take anywhere between 5-10 minutes, depending on your stove, heat, etc. It should bubble quite a bit at the end (be careful of the splatters - it's hot) and thicken considerably.


Transfer the mixture to a clean bowl and cool to room temperature. I refrigerated my initial mixture overnight. If you do this, make sure to pull it out in time to let it warm back up to room temperature. If you try to proceed with the rest of the recipe and the mixture is too cold, the butter won't absorb into the frosting like it should.


Once the frosting is completely cooled to room temperature (it should have no hint of warmth at all), beat the mixture with the vanilla on low speed until it is well combined, about 30 seconds (a stand mixer will work best for this). Add the butter, one piece at a time, and beat the frosting until all the butter has been incorporated fully, about 2 minutes. Increase the speed to medium-high and let the mixer work it's magic. Beat the frosting for five minutes, until it is light and fluffy. Let the frosting sit at room temperature until it is a bit more stiff, about 1 hour.
