How to Make OREO Cookies-Shamrock Cupcakes
Ingredients:
- 1 box Betty Crocker Super Moist Yellow Cake Mix
- Water, vegetable oil, and eggs (as called for on cake mix box)
- Mint green gel food color
- 2 1/2 cups from 2 tubs (12 oz) Betty Crocker Whipped Fluffy White Frosting
- 1 teaspoon peppermint extract
- 6 thins mint flavor creme OREO Cookies, cut into quarters (about 1 cup)
Directions:
- Heat oven to 350 degrees F. Place paper baking cup in each of 24 regular-size muffin cups.
- Make cake batter as directed on the box, stirring food color into the batter to reach your preferred shade of green. Bake cupcakes as directed and cool in pans for 10 minutes. Remove cupcakes from pans to a cooling rack and let them cool completely, about 30 minutes.
- In a medium bowl, mix the frosting with peppermint extract. Spoon about 1 cup of frosting into a decorating bag fitted with a 1/8 to 1/4-inch tip. Insert the tip into the center of each cupcake, about halfway down. Gently squeeze the bag while pulling upward to make the cupcake swell slightly, and let the filling come to the top. Repeat this step with all cupcakes.
- Spoon any remaining frosting into the same bag; generously pipe frosting in a circular motion on top of each cupcake, leaving a 1/4-inch border around the edge. Top with the OREO pieces.

Variation
For a chocolate version, you can replace the yellow cake mix with a chocolate cake mix. The mint frosting and OREO topping will still work wonderfully!
