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:

you will need 9 colours of dye.
I used 6 and for the 1st and 9th I made cocoa powder (taste &) colour.
Use gel or pigment and touch up any colours with liquid dyes.
Touch up dyes
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.
1)Spray oil the pan and all sides of the form Very Very well.
2)Dab off any running oil
Fill ONE (1) pan at a time, Outside ring 1st.
You will need to wash and dry the form for each pan - total 3.
Then fill Centre ring next.
[Sorry the photos aren't in colour order :'( ]
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.
Moments later Cake 1
Cake 2 (and a left overs cake)
Cake 3 and Cake 1 again - cooling 8)
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 :)
