1 teaspoon vanilla extract
2/3 cup shortening
1 (18.25 ounce) package devil's food cake mix
2 cups peanut butter chips
Preheat oven to 375° F.
In a medium bowl, beat the eggs, vanilla, and shortening with 1/2 of the cake mix until light and fluffy. Mix in the remaining cake mix and the peanut butter chips. Drop dough by rounded teaspoonfuls 2 inches apart onto ungreased cookie sheets.
Bake for 10 to 12 minutes in preheated oven. Remove from cookie sheets to cool on wire racks.
