Your Kid Wants a Themed Birthday Cake

You don’t have hundreds of dollars to spend on a custom cake, and you don’t want one from the local grocery store. What do you do? You make it yourself of course! Here’s how I pulled together a Sonic the Hedgehog cake for my 8 year old. Two toned blue buttercream, gluten free golden oreos, and a pack of tabletop decor in the Sonic the Hedgehog theme. I found some decorative clouds I had been stashing in my cake decor stuff and added them in.

I did a crumbcoat and refrigerated the cake for about an hour then took it out and did the darker blut frosting on the bottom, the lighter blue frosting on the top, and used my offset spatula to swirl them together where they met. I added some very imperfect trim, and the golden hoops, and added the toppers.

A Sturdy Construction and Thick Layers

The picture of the inside of the cake shows off the thick layers, and you can see a peek of the smoothie straws I use to support the height and weight of the cake. To get the thick layers I use an entire cake mix in a deep, 8 inch cake pan. the pans are 3 inches deep, vs the normal 2 inch cake pans you get in the store. These layers I actually baked a couple of weeks in advance, let them cool, wrapped them in plastic wrap then aluminum foil and froze them. I thawed them out a couple of days before I needed to make the cake and they were perfect. We prefer a more cake to frosting ratio and the thicker layers are less flimsy than thinner layers, so it all works out for us. The smoothie straws I just push into the cake after I assemble it. That’s it, I push them into the cake and trim the top off and frost it. I usually use four straws to make sure the cake isn’t going to slide. Ask me how I know the cake will slide lol. I’ve only had to remake a cake once, there have been a few lopsided ones throughout the years though. Those straws will keep it together even if it does lean a little.

The cake topper really, “takes the cake” I couldn’t resist guys

The Topper

I stumbled upon the idea of using table top party decor as cake toppers a year ago or so. I haven’t looked back. I just take the pieces I want and put a thin skewer stick on the back and pop it into the cake. Boom. Done. I paid $15 for this set of tabletop decor and I used it as the cake toppers, the table decor and I used them on the presents to make them “themed” without having to buy specific wrapping paper.

That’s it. I used a white sheet folded and laid down the middle of the table. Ribbon from my gift wrap stash, and a pack of tabletop decor. We used our own plates and utensils and you have a very affordable sustainable birthday party!

Go party sustainably and affordably!
