How To Store Leftover Birthday Cake Fudge

What Do I Do If I Can’t Find Funfetti Cake Mix? 

If your store doesn’t have any variety of funfetti or confetti cake mix, you can essentially make your own. 

Take a white cake mix or (as a last resort) yellow cake mix. Empty the box of cake mix into a large bowl and mix in about 1/3 cup of long sprinkles. Then continue with the cake batter fudge recipe instructions from there. 

Is There Another Type Of Sprinkles I Can Use For This Birthday Cake Fudge?

Yes! I like to use rainbow sprinkles for this great recipe because they are representative of festivities and celebrations, but you can use any sprinkles you choose. The long jimmies tend to be softer than the harder balls, but the size, shape, and color are completely up to you.
