These cookies are out of this world good. Peanut butter cookies stuffed with a peanut butter cup - how could it get much better? They're perfect for holiday gifting (but make sure to save a few for yourself!).
Preheat the oven to 375°F and grease a mini muffin pan. Unwrap your peanut butter cups and place in the freezer (this make them easier to push into the cookies without melting).
In a medium mixing bowl, whisk the flour, salt, and baking soda.
In a large mixing bowl or the bowl of a stand mixer, add the butter, peanut butter, sugars, milk and vanilla. Add in the flour mixture and mix until just combined.
Place 1 tbsp balls of dough into each muffin pan divot (you will have around 2 dozen). Bake in the preheated oven for 7-9 minutes.
Immediately upon removing the cookies from the oven, remove the peanut butter cups from the freezer and press into the centers of the cookies.
Allow to cool completely before removing from the pan.
Notes
*Use the spoon-and-level method to measure your flour to ensure your cookies aren't dry.**Your butter should be slightly softened so that it mixes well with the other ingredients. We recommend bringing it out of the fridge 30 minutes to an hour before using.
