Dreamworks Trolls Inspired Birthday Party

For my three children’s annual birthday bash, the theme we decided on was a Dreamworks Trolls birthday party which meant a lot of rainbows and bright, bold colors.

I will admit that this year was quite tame in comparison to past parties we’ve done.  And by “we” I don’t mean my husband and I, although he always graciously goes along with whatever crazy overboard plans I get in my head and knows better than to tell me to “take it easy.”  No, I’m talking about my two sister-in-laws who share my passion and extravagance when it comes to party planning.  

But in an effort to keep things small this year, I took on the party planning by myself.

And while I didn’t have the luxury of their help this time, I can’t exactly say that I flew solo because my 4 year old had a lot of input and devoted her afternoons to helping me make decorations out of tissue paper.

My quest for the perfect theme party started as it always does – Pinterest.  There I found inspiration and tutorials for decorations, food, cakes and games and filled my board with anything that fit the theme.  [Click here to follow my Trolls Birthday Party Pinterest Board]

And what actually came together was this…


A Trolls birthday party meant rainbows and bright colors so while this rainbow tissue paper tassel garland was tedious and time consuming to make but it had a huge impact and added tons of color throughout the house! 


I made the tassels little by little over the span of a few days and was surprised at how many they added up to when they were all hung.  In total I did two dozen of each color and was able to create a garland that was roughly 16 feet long and wrapped around my entire dining room!

Of course what’s a rainbow without a few white puffy clouds to dot the ends?  I made white tissue paper poms in three different sizes and grouped them in the corners where I hung the garland.  Command hooks worked the best to hang both the poms and the garland on the wall and thumbtacks for the ones that were attached to the ceiling.

The other large scale rainbow decoration I worked on for the Trolls birthday party was this rainbow ceiling canopy made from plastic dollar store tablecloths.


I attached one end of the tablecloths to the ceiling light fixture using a rubber band and some string.  Then I spread out and ruffled the other end and stuck it to the wall using double sided tape.  There was quite a bit of overhang which I debated leaving in place but ultimately trimmed for a nice, even look.  I loved the way it looked so much that it hung in my living room for months after the party!


I stumbled upon these happy birthday letter balloons at the dollar store for $4 for the entire set (which was pricey for the dollar store but a steal regardless)!  It fit perfectly with the Trolls birthday party theme!  I was skeptical about the quality because, well, it’s the dollar store but they were as good as any other foil Mylar balloons I’ve used in the past.  Turns out they were the perfect size to fit in this little gap at the top of the wall between my living room and kitchen.  They were easy to inflate and deflate with a straw and I will definitely use them again!

I found something similar on Amazon

I wanted to make sure that the Trolls birthday party theme was evident, and not just a generic rainbow party so I searched for a way to make the Trolls come alive! There is a section of our living room (i.e. playroom) wall where I’ve hung two rows of twine and normally hang my children’s artwork up with clothespins.  I had initially wanted my children to draw pictures of the trolls and rainbows and other things theme-appropriate to hang up there but they were not thrilled about that idea.

So instead I bought this downloadable clipart package from CariStudio on Etsy.

I inserted different pictures of each Trolls character into a Word document and printed them on card stock at our local Copy & Print Center. They turned out amazing!

The one thing my children asked for this year was a pinata.

And the only one I could find was this small Poppy one.  It was a pull string pinata so it was safer to use indoors but we weren’t too familiar with the process.  At first we tried to let each child have a turn and pull one string but that didn’t pan out so great so eventually we just made everyone grab one string and pull at once.

That worked much better and the kids excitedly rushed all over collecting candy just as I imagined, but it was over much too soon and seemed like a lot of effort for a few minutes of fun.  Next year, we’ll have to try this again and I’ll attempt to DIY one!

Side note – do not put pixie sticks in your pinata!  Because if they burst open during the process you will have white dust come flying out everywhere and guests will wonder where you imported that pinata from…

I downloaded this free printable Trolls bingo game from Best Toys for Kids and it was a huge hit!

We used M&M’s as bingo markers and anyone who got a Bingo got to eat their line! I again trusted my friends at our local Copy & Print Center to print and laminate it and they did not disappoint!  I even forgot to specify that it needed to be cut into pieces but they took care of all of that for me and the end result was a very professional looking bingo game that I’m sure we will play over and over again.

Ultimately, the Trolls birthday party was a huge success and the kids and guests all had a great time!  We played the Dreamworks Trolls Soundtrack in the background and turned it up for a dance party afterwards!

After the party, we donated the decorations to my daughter’s preschool.

6 Layer Rainbow Cake Recipe

We recently celebrated my children’s birthdays in one combined sibling birthday party and decided on a Dreamworks Trolls inspired theme which included a bright, bold, rainbow color scheme and an even bolder rainbow cake!

One of the highlights at all of the parties in our family is the cake, and believe it or not, cake decorating is my husband’s hidden talent.  This time, due to his hectic work schedule, it was a joint effort and I baked the cakes while he did the decorating.

We searched Pinterest for ideas and inspiration for our rainbow cake and decided that we just HAD to attempt a six layer cake – one for each color of the rainbow!

I used Wilton concentrated gel food coloring to get the bright, vibrant colors in both the cake and the buttercream frosting.

After preparing the cake batter, I separated it into six bowls of roughly 1 1/2 cups of batter each and then added the food coloring gel and mixed by hand.  I baked two layers at a time and then wrapped them in waxed paper and plastic wrap and froze them until my husband was ready to decorate.

I would love to be able to share the buttercream recipe with you as well, but it’s my husband’s secret recipe.  And it’s really only a secret because he doesn’t use one – he just throws a bunch of stuff into the mixer and it turns out incredible every time!

Thankfully you can find awesome recipes with tutorials at www.mycakeschool.com!

Here is one for the vanilla buttercream which we colored with the same gel food coloring.

Here is one for the chocolate ganache that we drizzled around the top of the cake.


I was lucky enough to find the Poppy & Branch marshmallow pops at the dollar store to use as cake toppers but unfortunately haven’t been able to find them for sale online anywhere to share with you.

As for the decorating itself, I’m going to make it sound much more simple than it actually is because my husband made it look a lot easier than it was.

After stacking the individual cakes in the right order, he filled them and did a crumb coat with plain white buttercream.

Then he mixed the buttercream into the six different colors.

Next, he piped a stripe of each color around the cake in the same order that the cakes were stacked.

Using a dough scraper along the side, he rotated the cake on the turntable to blend the colors together.

The top was covered in a layer of rainbow sprinkles with chocolate ganache drizzled around the top edge.

The result was a bright, colorful, rainbow cake that was beautiful inside and out!
