Heat oven to 350 degrees. Grease 48 mini muffin cups with shortening or nonstick cooking spray.

Stir cookie mix before measuring.

In large bowl, beat cookie mix, peanut butter, butter and egg with electric mixer on medium speed, scraping bowl occasionally, until dough forms. Add milk if needed.

Shape dough into 1-inch balls and place in muffin cups.

Press 1 peanut butter cup into each ball.

Bake 12-15 minutes or until dough is set and golden brown around edges of candy.

Cool 5 minutes and remove from pan. Cool completely for 30 minutes.

Melt chocolate chips and shortening in microwave for 45 to 60 seconds or until melted. Continue to microwave in 15 second increments, stirring until smooth.

Drizzle glaze evenly over cooled cookies.
