Chocolate cookie dough makes the ears for these puppy cookies. Little candies make his face. He's served on a stick for added fun.
Preheat oven to 350°F. Line 2 cookie sheets with parchment paper. Knead flour into cookie dough until smooth. Divide dough in half. Knead cocoa powder into one half until smooth.
Roll out vanilla and chocolate cookie doughs until they're barely 1/4-inch thick. Cut out 8 hearts from each using a 3-inch cookie cutter. Place the vanilla hearts about 3 inches apart on cookie sheet. Insert a lollipop stick into each heart shape. Slice the chocolate hearts in half lengthwise. Place on either side of vanilla hearts as the ears. Press 6 mini chocolate chips, pointed side down, on each of the vanilla hearts as shown. Bake until just golden, 10 to 12 minutes. Transfer the cookies to a wire rack and let cool completely.
Pipe 3 dots of frosting on the cookie, as shown, and attach M&Ms for nose and eyes. Tie a ribbon on the lollipop stick, if desired
