Making simple Lego decorations can be a fun and easy way add something special to your child’s Lego birthday party celebration. Here I share ideas for party decorations, a Lego cake, Lego marshmallow pops, and chocolate Lego minifigures. Let the Lego party begin!
Simple Lego decorations for your Lego birthday party can be low key or over the top (in a good way!).
If you want to see the cream of the crop when it comes to throwing a Lego party, head over to the Hostess with the Mostess. You will be amazed at the lengths that this rightfully called Hostess with the Mostess goes to, bringing Lego alive for her son’s party.
It’s truly impressive.
If you feel more comfortable on a smaller scale and are not ready for the effort it takes to achieve her complete Lego blowout of a party, try a few of these easy party ideas to keep the Lego theme going at your house.
Lego Buffet Table
Dress up the snack table with a Lego box that holds the snacks. I used the Duplo Lego bricks and built the sides up to a point that the bags of pretzels would stay put.
I think I would have continued this plan for the other snacks on the table because I liked the bright color it added to a simple thing like a snack of pretzels, but I ran out of bricks!
Backup plan B was to cover boxes with Lego paper to dress up the juice drinks.
I used Lego posters that we had gotten for free recently from the Lego store. The wall in my son’s room is decorated with one already so I didn’t feel badly cutting in to a few others.
Lego gives these away with certain purchases from time to time. I think they also offer a monthly calendar that would work well; Lego wrapping paper would also be festive here.
The Lego Cake
Here is a basic attempt at a Lego cake.
These cakes are all over the internet, I think even Better Crocker highlights this method on their site too. I don’t suggest it here as a novel idea, but I did learn a tidbit about icing cakes and thought it was worth sharing.
I should preface this tip as usual by mentioning that these ideas will help the amateur, home baker; if you already excel at this sort of cake decorating please send more tips my way! I sincerely could use them.
How do I decorate a lego cake?
Have you ever had the trouble when icing a cake, that the icing seems to take off the top layer of crumbs of your cake, leaving the icing with bits of cake spread throughout?
All of that hard work in baking the cake and wishing it comes out of the pan in (nearly) one piece is then ruined by the icing process. I have that trouble all of the time and have finally made progress towards eradicating it.
After the cake is completely cooled, wrap it in parchment then cover in foil and put it in the freezer.
There is no set time for freezing the cake. I have found that freezing it overnight works wonders, although I bet a few hours would suffice too.
When the cake is sufficiently frozen, then give the icing a try. Most of the crumbs stay put on the cake and icing is much smoother. Applying this first layer of icing is called a crumb layer in the baking world.
Essentially you are sealing in the cake and preventing the crumbs from showing through in the final layer.
The crumbs you see here in between the Lego studs are my first attempt. I used mini muffins for the Lego studs but the proportions were off. Switching gears and using brownies to make small cylinders was a good move.
Take this idea one step further: begin by icing the whole cake with the thinnest layer of icing that you can manage. After this initial layer is in place, put the iced cake back into the freezer for another period of time so that the icing sets.
Now when you add your final, decorative layer of icing, you are placing one layer of icing on top of the next and the crumbs have already been safely sealed underneath the first layer. Sounds simple but these steps make a big difference.
You’ll notice my cake is not one for a cake competition, there are many flaws.
I am still working on how to get the icing to be a smooth layer on the cake without showing my strokes with the offset spatula.
I tried one tip that I read somewhere recently: a hairdryer! Yes, I really did lug the hairdryer to the kitchen and tried to melt the outer layer of icing so that it was easier to shape. The efforts worked to an extent; the icing was smoothed slightly but overall I could use some more work on this trick.
Lego Marshmallow Pops
I saw the image of these Lego pops on Bakerella’s site, made by a woman named Amy who blogs at Living Locurto. Hers were adorable and looked like they came directly from a bakery or specialty store. I just had to give it a try for my son’s Lego-themed birthday party.
As with many things I make, the end result isn’t flawless, but the idea comes across well enough that 7 year olds recognized these as Lego minifigure heads so I’d consider it a success! I got a kick out these smiling yellow heads so that counts for something too.
I happened to use vanilla candy coating that I tinted yellow because those were the ingredients I had on hand. I think, next time, I would suggest using yellow chocolate candies designed for melting. I’ve had better luck with the consistency of the melted chocolate rather than the candy coating.
Here’s what I did:
First put the marshmallows on the sticks. I did two versions: the first time through I melted a small bit of white chocolate and dipped the end of the stick into the chocolate before poking it into the marshmallow. The second time I skipped that step and my marshmallow heads were no less sturdy because of it.
I liked Amy’s idea of using small marshmellows for the tops of the heads, but I chose to use smarties because the concave top of the smarties reminded me of the Lego piece. Dab a small bit of chocolate or candy coating on the top of the marshmallow and let the smarties dry for a few minutes.
Next you’ll need to melt the chocolate or candy coating. I used the microwave method, microwaving in 30 second increments on half power. This next step caused me a bit of trouble: coloring my vanilla candy coating to the right shade of yellow.
As soon as I added the food coloring, the mixture seized up (it must be close in composition to regular chocolate). I was able to remedy the issue with a small bit of shortening but not before having a small moment of panic!
I created a makeshift drying area by making holes in a cardboard box and allowing the pops to dry while standing up. It needs a few improvements that would help the pops stand vertically, but for the time being it worked.
Even more fun would be to let the kids draw faces on the pops themselves. For you skilled decorators, what about adding hair or hats made of fondant? The kids could customize their pops and even make images of themselves. Well I’ll save that experiment for another time. For today’s party this did the trick and was a cute addition to the party favors.
Chocolate Lego Minifigures
Oh what fun– a Lego-themed party!!
Here come the Lego men. We’re gearing up for my son’s 7th birthday and Lego is the word of the day around here. Lego men, Lego cake, Lego minifigure pops, Lego everywhere!
These ice cube molds sold by Lego make a perfect topping to a cupcake or a sweet bundle of chocolates for a treat bag, keeping within the Lego frame of mind.
I bought the minifigure molds at the Lego store and have seen Lego bricks ice cube trays on sale on eBay and a few other sites too.
I used them to make chocolates; you could also melt crayons and pour the wax into the molds which would make kid-friendly party favors.
How to use the minifigure mold
- Start with a clean and dry mold.
2. Melt chocolate (I used Wilton’s Candy Melts) in the microwave on half power in thirty second intervals until the chocolate is smooth when stirred.
3. Pour into the molds, using about a tablespoon for each minifigure. Don’t spray the molds with baking spray. I did that my first try and it was a mistake. You can see the spots that show the difference.
Now you’ll want to give the tray a good shake, trying to let the air bubbles out. I places the tray on a cutting board and then tapped and (gently) dropped the board on to the counter a few times. You’ll see the little bubbles popping to the surface. Not a big deal if you don’t get them all out but the finished product looks nicer without air bubbles.
Place into the refrigerator for about 30 minutes and then pop the chocolates out of the molds.
Note: you’ll see that first I used Pam spray to make sure my chocolates didn’t stick to the molds. This wasn’t necessary. In fact, the spray left the surface of the chocolates waxy and discolored. No problem, I re-melted the chocolates and tried again without covering the surface with spray. The chocolates turned out really well with no sign of the earlier mishap.
