Fault Line cakes have become a very cool and interesting trend in the cake world. It’s unfinished mid section of the cake, decorated to your preference has people all over trying new a different ideas.

I’ve even seen Fault Line cakes with macaroons in the mid section of the cake and that was just amazing. It’s like getting the best of both worlds, the deliciousness of the macaroons and cake at the same time! Who wouldn’t want that!

To celebrate the 4th of July, I chose to make a Fault Line Cake with red, white, and blue starts on the inside of the mid section of the cake. This would be a great cake to bring to your family cookout and I know for sure this will be a hit with everyone at there.

So how can we make one?

Tools needed:

* Cream Cheese Frosting
* Red, white and blue fondant
* Red and Blue velvet cake
* Cake spatula
* Sprinkles
* Mini Star Fondant Cutter

Step 1: Leveling and Stacking Cake

As with any cake that you make, it’s best to level the cake before stacking it. After each layer has been leveled, fill each layer with cream cheese frosting or any filling that you choose to use for your cake.

Step 2: Crumb coating cake

Crumb Coating a cake is very simple and easy to do. The crumb coat is basically a thin layer of frosting that locks in all of the moisture of the cake and will also stop the cake from crumbling.

After the cake is crumb coated, place it into the refrigerator to crust over for 30 minutes.

Step 3: Decorating Mid Section of the Cake

Now that the cake has been crumb coated, you can now begin decorating the mid section of the cake. For the mid section of the cake I used a small star cookie cutter to cut out red, white and blue stars for the 4th of July theme.

After all of the stars have been cut, place them onto the cake close together, without any gaps in between each star.

Step 4: Covering the Top and Bottom with Frosting

To complete the look of the fault line cake, begin piping around the bottom and top portion of the cake. Make sure to add a thick amount around the top and bottom so that it actually has that fault line look.

After piping the frosting around the cake, begin smoothing out the sides and the top part of the cake.

At this point you can paint the fault lines with edible gold paint or add sprinkles or any other type of decoration to the cake to complete your design.

You just made a Fault Line Cake!

As you can see from this simple tutorial, that Fault Line cakes are simply fun and easy to make. I love how they are very similar to the geode style cake.

The most exciting part about this cake is that you can switch up the design by adding anything you design to the middle of the cake.
