Here's a fun snack that sweetly sums up what fans know about Phineas and Ferb -- they're two smart cookies.
Download Phineas and Ferb Cookies Template* If the store-bought brand of dough you use is too soft to hold the cookie shapes while baking, you can knead in a little extra flour to stiffen it before rolling it out.
Phineas Cookie Instructions:
Print the template and cut out the pieces. Roll out the dough on a floured surface to 1/4-inch thickness.
Use the template and a knife to cut out an equal number of Phineas heads and cookie backgrounds. Bake the cookie cutouts according to the recipe directions and let them cool.
Note: It's best to bake the heads and backgrounds on separate cookie sheets because the smaller pieces tend to take a little less time to cook.

Frost the heads with the tinted cookie icing and set them aside until the icing hardens.

Meanwhile, use the fondant cutter to cut a pair of eyes for each Phineas head from the white candy melts. Use a bit of icing to stick a brown candy-coated chocolate atop each white candy circle.

Now create the hair shapes. For each one, fold a piece of green flexible fruit candy in half (keeping the plastic on the outside) to create a double thickness. Then tape the hair template piece to the plastic and cut out the shape with kitchen scissors. Remove the template and the plastic.

When the icing is set, assemble each cookie by using dabs of frosting to stick a Ferb head on the cookie background. Stick a hair piece to the top of the head. Then stick a pair of eyes in place, overlapping them slightly as shown. Add a jelly bean half for an ear and a piece of a slivered almond for a grin. For a shirt top, use a red gummy candy half and trim the bottom to fit.
