Rainbow Cake Recipe
I am looking for a Rainbow Cake recipe that not only has five to six colors but the cake is flavored accordingly, as well. Such as the yellow being lemon, the green being lime, etc. My guess is that I could use jello, but how much????
Google for this, I'm sure you'll find some instructions. Either jello or separate the batter, flavor and color it accordingly and marble it together gently or blob into the pan in sections.
White cake mix + food coloring (gel gives the brightest colors) + a few drops of extract in whatever flavor you want.
Frankly, the 5 or 6 flavors is kind of... flavor overload.
My MIL used to make "Rainbow Cake" back in the 60s and 70s, she only used one color though...I think. I should pull out the recipe. It was just a sheet cake make from boxed white mix, with holes punched in after baking, and jello (usually red) poured over. When set, it was topped with Dream Whip. She was a real from scratch cook but this one was great anyway. Maybe she put sprinkles on top for the "rainbow" effect?
