Funfetti Cake issues

[CuppaTeaAndAJammieDodger]

I tried making one of these for my daughter's last birthday, but the hundreds and thousands that I used just bled into the cake mix so I ended up with a brown cake with white crunchy bits in it. Has anybody got any suggestions as to the brand of hundreds and thousands to use? What should I be using something different?

I used Betty Crocker ones and hey seemed to hold up quite well.

Thanks Fartnisseverbeans - your name made me laugh

You need the big thicker American style sprinkles. Amazon have them. Or eBay. They are brighter and bigger too and work well.

Ck jimmies are a brand that work and can be bought from amazon, or in individual Colorado from sugar shack.co.uk. Or 100s and 1000s from australia which are what I like best.

*colours not Colorado

You need sprinkles made with artificial colours. The ones that are widely available in supermarkets are made with natural colouring.
