Step 1

Preheat oven to 375 degrees F (190 degrees C). Whisk together the flour, salt and baking soda. Set aside.

Step 2

Cream together the butter, sugar, peanut butter and brown sugar until fluffy. Beat in the egg, vanilla and milk. Add the flour mixture and mix well. Roll the dough into 40 balls and place each into an ungreased mini muffin pan. The balls should be about 3/4 inch in diameter.

Step 3

Bake at 375 degrees for about 8 minutes. Do not overbake! Remove from oven and immediately press a mini peanut butter cup into each ball.

Step 4

Place in the freezer for about 7 minutes and allow the cookies to chill. Pop each cookie out of the muffin tin.

Step 5

Enjoy!
