There is only 1 item that you’ll want to definitely have on hand and it makes or breaks the presentation I’ll share that in the equipment needed to make this fabulously easy Mexican-themed party recipe for a tasty cake!

How To Make A Fiesta Cake
I promise you I was not sipping on Margaritas while I made this cake, but it might seem like it, because of how it all came together!

So, I was planning on making this party cake, but I had messed up the baked cake and it just kept cracking so I seized the moment and cut the cakes into cubes rather than dealing with the cracking (because I overbaked them)
However, I have no shame in sharing that story because I am human and we all have issues when we bake and cook and I am hardly exempt, I just moved through the issue and created a fun, color-popping fiesta with my new cake!
Step 1: Baking The Cakes For the Fiesta
Prepare your box cakes according to the instructions on the box.
Step 2 is super easy all you have to do is transfer the batter to your choice of the baking pan either 2 round pans or 1, 9″ x 13 pans.
Step 3 is just to bake the cakes according to the box instructions and then remove and allow them to cool completely.
Step 4: Cubes and Your Mexican Party Cake

Once cooled you will cut your Mexican cake for the fiesta into cubed pieces and set it aside.

Step 5: Prepare The Icing for Your Mexican Themed Party Cake
In a deep mixing bowl, combine butter, vanilla, cinnamon, and milk (or use a different substitute as listed above for the dairy if you can’t have dairy)
Next, add the confectioner’s sugar and stir and if the consistency is not right you will add more confectionary sugar.
Do not add too much confectioner’s sugar at one time or it will not work, just watch the consistency as you add it in little by little, this is very important!
Once it is thick enough to pipe through a zippered bag or pastry bag, stop adding confectioner’s sugar, and don’t add more milk (or whatever liquid you have chosen to use)

NOTE: your ideal icing needs to be looser than it would be for spreading, yet able to stick together when squeezed through the bag, and trust me, you’ll know it when you see it, as this recipe is not hard!
Step 6: Time To Introduce the Churro Flavor Icing Into Color
Start by dividing the icing evenly into portions into 3 separate bowls so you are basically 1/3’ing it per bowl.
To each bowl, you will add the special food coloring and then mix!
Next, add food coloring to each, stir and if it is not vibrant enough add more color, but work with the icing by combining before you add more color, ensuring have stirred it enough.
Step 6: Load The Churro Icing Into Pastry Bags
Fill your pastry bag or zippered bag with each respective color times 3 colors.

To make this easy, place a glass or a tall vessel on the counter, place the bag inside the glass and hang the open edges of the bag over the glass to easily fill the churro flavored colorful icing into each bag, then seal the top.
Step 7: Prepare The Glass Pedestal Trifle Dish That Will Share the Windowpane Of Mexican Fiesta Colors
First, you will add a tossed handful of colorful fiesta sprinkles to the base of the glass pedestal trifle which begins the coloring!
Add your first set of cake cubes to fill the first layer, just toss them in, without true placement.
Then you will choose whatever color of icing you want to start with and randomly stripe the cubes.
Repeat this with the remaining colors until you have striped the first layer with all 3 fiesta colors.
Follow this with a quick dash of light colorful fiesta sprinkles.
Repeat the same steps as above for the second layer, including the icing and sprinkles.
Step 8: The 3rd Layer Color Pop That Makes The Mexican Cake A True Party!
For the top layer, you will repeat all of the same things you did for layer 1 and layer 2, but we are going to add a true color burst.
It’s a burst of color created by using the interior of the glass bowl, and piping icing down the sides so it streaks and creates what looks like a window with colorful glass panes and this is why it is so important that the icing is not runny!
Next, add in the fake sparkler picks either inside of straws or just as they are into the Mexican-themed cake cubes.
To add even more of a Mexican theme to the party cake, you can add a few colorful napkins to pull the colors of the festive cake outward, and some small Mexican party toys.
Serve immediately.

How To Store Fiesta Cake?
If you are fortunate enough to have any leftovers of this party cake, then you will need to store it, here is how!

The Best Way To Store Leftover Mexican Party Cubed Cake

Fiesta Cake FAQs
Should I Only Use Primary Colors For the Churro Icing?
No!
Have fun with the colors of this fiesta cake, personalize them to match the Mexican themed party you are hosting.
Look at the colors used for Día de Los Muertos, and any other holiday and use that as inspiration!
Can I Use A Sheet Cake Instead of Round Baking Pans?
Yes, you can use any mold you want to prepare this fiesta cake, just cut it into cubes, and do note that you may have thicker pieces, depending on the pan size used.
Do I Have To Use A Glass Trifle Bowl On A Pedestal?
No, you do not have to use a glass trifle bowl, but when it is in the glass trifle bowl and on a pedestal it does become the center focal point of your Fiesta table. You can use a large glass bowl instead or single-serve glass parfait cups as well.

Color Gives The Fiesta Cake A Brilliant POP!
While I love the primary colors on this fiesta cake, I will say that I have done the same party cake in hot pink and black and it just snaps!
Since you are not icing the cake, but rather drizzling the cubes, it kind of soaks up the icing a bit. But, there are no holes to poke, it’s just easy!
