Sift together dry ingredients (flour, salt, baking soda) and set aside.
Cream together softened butter, sugars and peanut butter until fluffy.
Beat in eggs, vanilla and milk.
Slowly add in dry ingredients until mixed well.
Shape into small balls, and put each ball into ungreased mini muffin tin.
Bake at 375 for approximately 8 minutes. Do NOT overbake.
Remove from oven and immediately press a Reese’s Peanut Butter Cup into each ball.
Cool.
While cooling, prepare the drizzle - slowly melt peanut butter chips with shortening. This can be done over the stove in a small saucepan or in the microwave on a low setting.
Drizzle over cookies.
Carefully remove from the muffin tin and serve. These cookies go perfectly with a nice glass of milk!
Notes
For a small batch, just ½ the recipe. You can also omit the drizzle.
