I think this is one of the most fun cakes I have ever made. I love it! It was for my “baby” on his 7th birthday. I love how he added his power rangers for the finishing touch (he wanted them on the cake but I said they looked so much better all around it! 🙂 )
First I got my cake the right shape- the sprinkles wont hide any funny shapes! This technique is what I used.
For this you need your cake room temp so the sprinkles will stick. I dumped some over the side- but found that filling my palm and then GENTLY tapping them in with the side of my hand as I moved up the cake works really well!
(To get the balloons in the cake I put the strings through a straw that was cut shorter than the cake, taped them, then stuck the straw into the center!)
