Fruity Pebbles Rainbow Pinata Cookies

My daughter is funny. She always thinks they know what mom is up to, but I had her totally surprised with this cookie. She walked in and out of the room while I made these cookies and every time she said, “Oh I see now, you are going to….” 

My reply was always, “Nope, wait and see.” 

Boy was she surprised when I handed her the finished cookie. 

Fruity Pebbles inspire fun in the kitchen and the colors are perfect for a birthday party or even just a lunchbox surprise for your kids. But I love the idea of these Rainbow Star Pinata Cookies for a rainbow birthday party — imagine everyone’s surprise when they took their first bite. Makes me giggle just thinking about it. 

Oh, and did I mention these cookies are delicious! You can’t go wrong with the fruity flavor of Fruity Pebbles with sugar cookies!

Rainbow Star Pinata Cookies


  • Fruity Pebbles
  • Two packages 16 oz refrigerated cookie dough 
  • Wilton gel color
  • 7 tablespoons cup flour
  • Vanilla icing

Fruity Pebbles Cookies Ingredients


Divide cookie dough into seven equal parts. Add food coloring to each part, I use Wilton gel color to get the bright vibrant colors. I used pink, red, orange, yellow, blue, purple and green — the same colors that are in the Fruity Pebbles. I kneading the color into the dough with my hands to be the easiest way. 

Colorful Cookie Dough

While adding the color, also add 1 tablespoon flour to each of the seven dough balls. This will give the cookies a little extra firmness when cutting shapes. (Note, if you use fewer colors the ratio will change. You should use roughly 1/4 cup per 16 oz package.) 

Place colored dough balls in freezer for one hour.

Remove dough from freezer and break into crumbles.

Cookie Dough Crumbles

Roll dough crumbles together directly on your cookie sheet. I recommend using a silicone Silpmat to keep cookies from sticking – I never bake without mine anymore! 

Bake at 350 degrees for 12 minutes.

Remove from oven, and while cookies are still warm use cookie cutters to cut out shapes. In one-third of the cookie shapes cut out a smaller shape from the middle (I used a smaller star, but a smaller circle would also work.) Allow cookies to cool in place.

Star Cookies Recipe

Once cool, remove cookies from the sheet and assemble.

Star Cookies

Place icing in a plastic bag and snip off the tip. Pipe icing onto each of the points of the star of one solid cookie, place a cookie with a hole in the middle on top. Fill hole with Fruity Pebbles. Ice the points of the star and layer a third (solid) cookie on top.

Note – I used store-bought icing this time, but if you want to make your own this buttercream icing is my go to.
