I love my kids. And, since their birthdays are 10 days apart (well, 2 years 355 days apart, to be exact), we always have one party for them. Since it’s a joint party, I try to come up with a theme that will fit boy or girl. I saw these awesome sprinkle cakes on Pinterest. Everyone’s all, “oh, it wasn’t that hard to do. Just do this and this.” Hmm, seems unusually easy.

And, to match the colorful sprinkles on the outside of the cake, I decided to make a rainbow cake on the inside. That part actually wasn’t as hard as you’d think, and totally worth the “ohhhs” and “awwws” when I cut into the cake.

Ready to see how I did it?

PS, boxed cake mix is totally your friend. Totally. I used 2 white boxed mixes and followed the directions. I stirred up 1 box at a time. Then I sprayed 3 round cake pans. But, before I poured any cake into the pans I made sure to cut out a piece of waxed paper to fix the bottom of the pan. After the pan was sprayed, I laid that waxed paper in the pan and then put a light coat of spray over that. This allows your cake to fall right out of the pan. Well, pretty much. (:

I divided the cake mix into three bowls and added food coloring to make yellow, purple and pink to the first three bowls. And stir, stir, stir.


Pour into greased and waxed cake pan and bake as directed on box. Don’t over bake. While these three were baking I stirred up the second cake mix. I divided batter into three separate bowls and then made blue, green and orange. When the cakes are finished baking, place a wired rack over top of pan and turn over. Carefully remove waxed paper. Then place hand over bottom of cake and quickly flip to your hand and back to the wire rack. If you keep the cake upside down on the wire rack, you may get a cracked cake (my pink cracked because of domed cake). Continue with all cakes.


It’s okay if you have wire marks on the cakes, you’ll be frosting. Now, let these cakes cool completely!


While cakes are cooling, stir up your favorite buttercream frosting. I’ll add that soon (and by soon, I mean, whenever I get around to it, I have kids and a job and a husband and Facebook). This one’s a good one though. Mmm. Great bakers say, “used boxed cake and your best frosting.” My sister told me that and she’s a great baker. (:


Cut a round piece of cardboard a little bigger than your cake pan. Then cover with foil. Add a dollop of frosting then start with your first layer of cake. I knew I wanted to go in rainbow order. Roy G Biv. Red, Orange, Yellow, Green, Blue, Purple. These are the colors of the rainbow. The V is Violet. (:


In between each layer add a small amount of frosting. Or a lot, I guess, it’s your call. It’s your cake. I knew we’d have a lot of frosting on the outside so I didn’t do a huge amount on the insides. If my cakes were too domed, I used a serrated knife and sliced it flat, or flat-ish. I used a piece of plastic wrap to push each cake down. My cake was soft and the tops of the cakes were really tacky. This plastic wrap worked awesome. Then I was able to really push down the cakes.


It’s pretty amazing, isn’t it?


Now, you’ll be doing what called a crumb coat. This is a thin layer of frosting on the outside of the cake. It basically holds the crumbs in. It’s kinda hard to do, because the cake is soft. But, just do it. It’s a must. You can thin your icing if it’s too thick and the cake is really pulling off.

Then you’ll need to let this coat of frosting dry completely. I made my cake 2 days before the party, so I stuck this in the fridge like this, with the crumb coat. It stayed in there overnight. Pretty much a full day. Then I pulled it out the next day and whipped up another batch of butter cream frosting.


This doesn’t have to be perfect. But I’d put it on kinda thick.


Then it’s sprinkle time. You can see I did two different kinds. That’s because it was a boy/girl joint party. And I’m awesome. But really, all those people who say sprinkle cakes aren’t that hard. They are. Okay, they’re not hard like labor, but really, you’ll have sprinkles everywhere. I mean everywhere. I put a sheet of foil under the cake (this is why the cardboard is necessary) and then I just started dumping sprinkles on top. I had to be careful not to over dump since I was doing half girl and half boy sprinkles. Then when it came to the sides I poured sprinkles in my hands and started slapping them on. The sprinkles and swearwords were flying. Son of a. Now I have sprinkles in the air vent. Great.

Cover any vents with a towel. Heck I’d say, don’t use foil, put down a towel and then put your cake on a towel. The foil on a hard countertop is just adding insult to injury here. Did that even make sense? Either way, use a towel. It’ll cushion those bouncy little bitch balls. (;


Then I added those white bigger sprinkles. One. By. One. Yep. My dad was impressed. I was going to do three rows to really show the difference, but I was tired. And my kids were watching, so I had to put away the swearwords. I placed my cake on a pretty, glass platter and piped frosting around the edges.



Looks super cute one color too.


I’m a sucker for pinks though. I loved it so much more when it was done.


So worth it watching these two gingers blow out the candles.


Whoa. You made that? Yes. Yes, I did.


It’s colorful. It’s a party.


Now go out there and make a rainbow sprinkle cake for someone you love. You’ll thank me, I promise. Well, after you’re all done.
