Clam Shell Cookie Ingredients

48 NILLA Wafers
1 tub vanilla marshmallow frosting
24 white Sixlets candy
Food Coloring in choice of colors (we used purple, teal, pink, & yellow)

How to Make Clam Shell Cookies

Spoon frosting equally into 4 bowls. Add 1-2 drops of food coloring to each bowl and stir to mix well.

Spread a spoonful of frosting onto each NILLA Wafer. Or, if you want to give your clam shell cookies a fancier look, pipe the frosting onto each cookie using a decorative tip.

Then, place a white Sixlet candy onto the frosting of each cookie. You will want to place the candy a little off-center (see image for placement).

Place another NILLA Wafer on top to finish off your clam cookies.

Serve and enjoy!

I hope you and the little ones enjoy this sweet summer treat!
