Mini Funfetti Sandwich Cookies

Are you enjoying all the fun ideas for Rainbow Week? I hope so…because I’m having a blast creating them for you! From the Mantel…to cupcakes…to a wreath…and now…Mini Funfetti Sandwich Cookies…the Rainbow fun continues!

These cookies are similar to Whoopie Pies, but since I didn’t use a traditional whoopie pie filling, I didn’t think I should call them that. Whatever they are called…I think they are so cute…and yummy, of course!

The cookies are made with 3 simple ingredients…a Funfetti Cake Mix, butter and 1 egg and they are filled with brightly colored Buttercream Frosting, in colors of the Rainbow. And we can’t forget the sprinkles…lots of sprinkles!
