Welcome back to Cake Week! For five jam-packed days, I’m teaching you how to make professional looking cakes at home, so you can avoid those high bakery prices. You can find links to all posts in the series HERE.

This girl makes decorating a cake look so easy! I'm going to try this instead of buying a sheet cake for my daughter's next birthday party. My biggest takeaway—level your cake BEFORE you decorate!

When it comes to cake decorating, the ultimate culmination of skills come together for one, and only one project—the actual cake!

Today, we’re going to create a simple, yet festive celebration cake that tastes better than the ones you pick up at the grocery store, and costs a lot less than your local bakery.

Now, let’s be reasonable. If you’re looking for a crazy Cake Boss cake, then this tutorial probably isn’t for you. However, one of my favorite things about this cake is it’s not only pretty {and easy!}, it’s also customizable for just about every occasion—retirements, communions, graduations, showers—anything!

This five-minute video shows you how to assemble, frost, and decorate this simple cake. Plus, since it only uses THREE decorating tips, you don’t have to go out and buy a huge set to start decorating!


List of Tools Used:

If you’re not sure how to fill a decorating bag, this video gives you a quick overview.

And in case you’re wondering about my super secret cake recipe, it’s a box mix! I swear by Pillsbury Moist Supreme cakes and all my customers would rave about how good they are. It is also the only instance where the word moist is allowed in my house. 😉


Troubleshooting Tips:

  • If your spatula picks up crumbs while icing your cake, thin down your icing with a little water until it’s easier to spread. Always wipe off the crumbs before dipping back into the icing bowl.
  • Be sure to keep consistent pressure on the bag and go slow while you’re writing the message on top. We want the icing to fall on it’s own to create soft loops and letters. Don’t force it!


When you make cakes for special events, there’s always the question of how much cake to make. For instance, How do you know an 8″ round will be enough for a party with twenty guests? How much icing should you make to cover {and decorate} said cake?

You don’t, unless you can magically estimate like a pro.

That’s why I use a baking and serving cheat sheet to tell me the exact amounts I need. This sheet has served me well during my years of professional cake baking, and I still use it to this day!

    1. I’d tell you that you should have someone else do the baking so that you don’t have to make your own birthday cake – but I made my own cake for my college graduation party a few years ago, so I guess I can’t. πŸ™‚

          1. I’m a sucker for homemade cakes but its an excuse to bake which is all I need lol

          2. Celebrate Thursday – I think you should make a cake for that! Problem solved! πŸ˜‰
