I have wanted to do this for awhile. It turned out great! for the first time I have ever made this.
It's a homemade cake (not a box mix), I have found that helps with the food colorings cook time - being as homemade cake is dryer. I think the colors should be mixed up more, because it's hard to tell indigo from violet. I did Roygbiv, but for the 1st and 9th color I made Chocolate. The squares could be more square, but thats a batter amount per color thing...I think? It was my 1st attempt. lol
The cake itself I made vanilla, but should have flavored it more because after food coloring it had no real vanilla taste of its own. So I made butter rum butter cream frosting :) It smelled and tasted great! :)
Thanks for looking :)
Checkerboard cake recipe is a Wiltons' scratch cake. This is also where you can get a cake form (see link for cooking instructions):
2 sticks butter or margarine softened
2 2/3 cups granulated sugar
2 teaspoons vanilla extract
4 cups all-purpose flour
1 tablespoon baking powder
1 teaspoon salt
2 cups milk
4 ounces( 4 squares) semi-sweet chocolate melted" ~Wilton
If not I was thinking maybe the form can be made by cookie cutters (size 2 1/2 inch for centre and 5 3/4 inch for middle ring) , by this process:

Don't bother washing your measuring cups yet.
1)Leave ALL the batter un-coloured, Until you portion it out.
Centre ring = 3 TBPs
Middle ring = 3/4 cup
Outer rint = 1 1/3 cup
...of the batter
2)"Portion" - Then Dye to tint wanted, Always remember batter cooks to a darker shade.
Then fill the middle ring Last.
Then Remove the ring form (and wash it).
NOTE: To lift out form -- Turn the ring form like the steering wheel of a car -- left to right and back slightly while shaking like you have a cold and lifting straight upward...it sounds funny but the batter will stay in colour place better.
I ..ahhh ...forgot to picture it before putting it in the oven but you get the idea from this shot.
1) Make your favorite white frosting, flavor with any clear coloured extract.
2)Be-careful of crumbs, while spreading a thin layer of frosting between each cake layer. (layer 1,2,3 Cake)
3)Frost the whole cake and decorate if you like.
Thats it! :) hope my directions are good enough lol
Thank you for reading :)
