Peanut Butter and Chocolate Marbled Cookies

Heat oven to 375°F. Line small muffin cups* (1-3/4 inches in diameter) with paper or foil baking cups, if desired

Stir cookie mix, 2 tablespoons oil, water and egg in medium bowl until soft dough forms.

Set aside 1 cup dough. Add cocoa and remaining 1 tablespoon oil to remaining dough, blending well. Roll together a pinch of peanut butter dough and a pinch of chocolate dough to make 1-inch balls. Place one ball in each paper-lined or ungreased muffin cup. Do not flatten

Bake 8 to 10 minutes or until cookie surface is set. Remove from oven to wire rack. Cool 2 to 3 minutes; press mini peanut butter cup at an angle into each cookie. Cool completely. Makes about 36 cookies.

*Cookies can also be baked on cookie sheets. Place balls on ungreased cookie sheet; bake as directed. Cool 1 minute; push mini peanut butter cup at an angle into each cookie.  Cookies will crack.  Remove from cookie sheet to wire rack; cool completely.
