How to Make a Floral Birthday Cake

You have probably seen these floral cakes before, they are the perfect little gift for those who don’t want to eat cake for their birthday.  Perhaps you will be invited to a birthday party that asks you not to bring gifts, and you know there will be a cake there anyway.  One of these little flower cakes is the perfect little gift.A-Floral-Birthday-CakeIsn’t this a sweet way to celebrate?  No calories are guaranteed, and I made this whole thing for $14.00!

How-to-make-a-floral-cakeI began with two blocks of wet floral foam.  I buy my Oasis Floral Foam at Amazon, of course the more you purchase the less expensive it is.  You can buy an Oasis brand Floral Cake form, but it is more expensive, so I have just cut my own as shown above and below.  I soaked them and set them out on an oversized ceramic platter.  You might want to purchase an inexpensive disposable tray that you can give away with the cake with the platter without your recipient having to worry about returning it.  I made this on my own platter so I am not including that in the $14.00 cost.


The next step is to find a round bowl or vase to use to help you cut your foam into a round form as a base for your cake.


Use a knife to cut around the bowl and peel away the excess foam.  If you were to begin with the pre-formed cake form it would look similar, like this:

Now begin to put in your flowers.  I used pink and white carnations for the base, just like you would have trim around the base of your cake.  Carnation stems are fairly stiff so you shouldn’t have any trouble pushing those into the wet foam.  You want to have very short stems so they don’t need to go in a long way.


Next I added lavender daisy mums all the way around my cake.  The mums have a less stiff stem, so be careful not to bend them when pushing the stems into the the foam.  You will only want a stem about 1/2 to 1 inch long to push into the foam.


I used miniature pink carnations for the trim around the top edge of the cake and then filled in the top with more of the daisy mums.  I finished off my cake with birthday candles and my cake was complete!

  1. this is beautiful! Thank you for sharing at the Thursday Favorite Things blog hop. Watch for your featrure on Monday xo

    1. Thank you so much Katherine! I will be so excited to see my cake featured! Hugs! Chloe

  2. Are you using real flowers or artificial flowers on this floral-birthday-cake? It is beautiful.

    1. Hi Patricia! Thanks for stopping by! Those are all real flowers, mums and miniature carnations I picked up from my grocery store floral department.

  3. I have two questions, how long do the real flowers last? And do you hot glue the 2 foam blocks together, or do they stay in place once you stick the flowers in?

    1. Hi Sarah! Thanks for asking! The two blocks stay together without anything holding them. If you are concerned, you can always use a couple of thin wood skewers, but just stick them into the two halves in the middle, don’t let them extend toward the edges or you might have problems with your stems of flowers running into them. If you put your “cake” on a plate with a small lip on it, you can continue to add a little bit of water to the base each day. You can also mist the arrangement with water. With mums and carnations you should e ale to get between five and seven days out of your cake! Happy arranging!

    How many flowers did it take to make this flower cake?

    1. Hi Darlene, I got all of my flowers at my grocery store. I used 7 pink and 7 white full size carnations, one bunch of white miniature pink carnations and one bunch of lavender daisy mums.

    Just found this post. My friend has a birthday coming up and I think she would like this and it would be so fun for me to try. Is this cake form make a ~6 inch x 4 inch cake? Thank you! Have you ever used a plastic stand for floral cake?


    1. Yes, that seems to be the correct size. I have never used a plastic stand for a floral cake. As long as it is sturdy, you will be fine. I usually set mine on a glass plate that have a bit of alip on it, because the floral foam may ‘leak’ a bit of water and then put it upon a ceramic cake plate I have. I hope that helps, they are always a big hit and so easy to make!
