Peanut Butter Oatmeal Cookie
- 1/2 cup butter room temperature
- 1/4 cup crunchy peanut butter
- 1/2 cup sugar
- 1/2 cup brown sugar
- 2 eggs
- 1 tsp vanilla
- 1 3/4 cup flour
- 3/4 tsp salt
- 1 cup rolled oats
Chocolate Buttercream
- 1/4 cup butter
- 2 1/2 tbsp cocoa powder
- 1 1/2 cups powdered sugar
- 2 tbsp chocolate pudding powder
- 1 1/2 tbsp milk
- 1 tsp vanilla
Peanut Butter Oatmeal Cookies
Preheat oven to 350°.
Cream together butter, peanut butter and sugars. Cream for 3 minutes, the mixture will be light and fluffy.
Scrape the sides of the bowl and add in the eggs and vanilla. Mix until combined.
Add the flour, salt and rolled oats to the bowl and mix thoroughly.
Scoop the cookie dough out onto a parchment paper lined cookie sheet.
Bake for 8-10 minutes, or until the edges barely start turning brown. The cookies probably won't change shape much while cooking, that is okay.
Right after the cookies are pulled out of the oven, take the back of a glass drinking cup and smash the cookies flat. Let them cool on the hot pan.
Chocolate Buttercream
Place all ingredients into the bowl of a stand mixer.
Using the paddle attachment, starting slowly, combine the ingredients.
Once the ingredients are mostly combined, turn the speed up as high as possible and let the buttercream whip for a few minutes until light and fluffy.
Assembly
Each sandwich will use two cookies.
Frost the backside of one cookie with a generous amount of frosting.
Top the frosting with another cookie. The backsides of the cookies should be touching the frosting, so the pretty side of the cookie is facing out.
