I'm thinking of trying a blue raspberry cake for my daughter's 3rd birthday but I can't find a recipe anywhere! I am thinking I could just add blue raspberry flavoring to a white cake, i.e. jello mix or koolaid drink mix--just not sure how it will turn out. Has anyone else tried this? BTW, I am going to make a lollipop themed cake and blue raspberry is her favorite flavor so I thought it would be fun to try something new.

if you add a few tbsp of jello to a cake mix you will get blue raspberry

Thanks I bought some of that and also a Koolaid drink mix packet, but ended up using the Koolaid. Thanks!
