1Heat oven to 350°F. Place paper baking cups in each of 24 regular-size muffin cups. Bake and cool cupcakes as directed on package for 24 cupcakes.
2Meanwhile, cut fruit snack into triangles. Roll up fruit snack to make a carrot shape. Repeat with remaining fruit snacks to make about 30 carrots. Cut green sour candies in half crosswise; cut each half into quarters lengthwise to make thin strips of green candy. Press thin green strips into large end of carrot to make greens on carrot. Repeat with remaining candy.
3Spread frosting over cupcakes. Sprinkle with cookie crumbs. Randomly place carrot shapes on tops of cupcakes or press them into cupcakes to make them look like they are planted.
